(Wikipedia) The ground state of a quantum mechanical system is its lowest-energy state; the energy of the ground state is known as the zero-point energy of the system. An excited state is any state with energy greater than the ground state. The ground state of a quantum field theory is usually called the vacuum state or the vacuum.

state axiom of quantum mechanics: "physical states are described by vectors of a Hilbert space, i.e. physical states are mapped injective onto the radiances of a Hilbert space."quantum gravity is a field of theoretical physics that seeks to describe the force of gravity according to the principles of quantum mechanics.

The Higgs boson combines the existence of mass together with the action of the weak force. But why it provides especially to the quarks that much mass, is still a mystery.

"Indeed there is no observation concerned with the geometrical shape of a particle or even with an atom." (E. Schrödinger)

               Mass is essentially the manifestation of the vacuum energy

The Standard Model of Elementary Particles (SMEP), including the Higgs mechanism, is concerned with gauge theory and variational principles (energy and operator norm minimization problems), whereby each of the 4 (observed) Nature forces are related to a specific gauge group. The model does not provide any explanation where the related elementary "particles" are coming from (or have been generated out of "first mover" resp. out of mass-less photons) during the inflation phase of current big bang assumption and why their mass have their specific values. We propose an alternative mathematical framework, which replaces gauge theory and variational principles (with its underlying concept of exterior derivatives and tensor algebra) by (distributional) Hilbert scales (enabling an inner product) and variational principles. As a consequence, the vacuum energy becomes an intrinsic part of the variational principles, i.e. is identical for all considered Lagrange resp. Hamiltonian mechanisms, while the corresponding "force" becomes an observable of the considered minimization problem;

The conceptual idea

The Berry-Keating conjecture is about an unknown quantization H of the classical Hamiltonian H=xp, that the Riemann zeros coincide with the spectrum of the operator 1/2+iH. This is in contrast to canonical quantization, which leads to the Heisenberg uncertainty principle and the natural numbers as spectrum of the harmonic quantum oscillator. The Hamiltonian needs to be self-adjoint so that the quantization can be a realization of the Hilbert-Polya conjecture.

The central concept is about a proposed alternative harmonic quantum energy model which enables a finite "quantum fluctuation = total energy". The model is based on a fractional (distributional) Hilbert space framework, enabling a self-adjoin Hamiltonian operator. It provides a truly infinitesimal geometry.overcoming current handicaps of the manifolds framework of Einstein`s field equations (differentiable (?) manifolds resp. exterior (differential) algebra), while, at the same time, the Hilbert space provides a closed subspace.of the L(2) test space, which enables continuous spectra.

1. Current gravity model & its handicaps
The main characteristics of current gravity model and its related handicaps regarding the physical model requirements are

a. metric space, affine connexions  
 handicap: no scalar fields (vector fields, only), no (infinitesimal) geometry

b. differentiable manifolds
handicaps: physical justification is only about continuous manifolds, additional regularity requirements are purely mathematical model driven

c. exterior differential forms, exterior product, exterior algebra
handicaps: no geometry, gavitational collaps and space-time singularities not covered adequately; if physical singularities in space-time are not to be permitted (R. Penrose) inside such a collapsing object at least one of the following holds

- negative local energy occurs
- Einstein's equations are violated
- the space-time manifold is incomplete
- the concept of space-time loses its meaning at very high curvatures, because of quantum phenomena

2. Current quantum model & its handicaps
The main characteristics of current quantum model and its related handicaps regarding the physical model requirements are

a. separable Hilbert space
handicaps: location and momentum operator have different domains (separable Hilbert spaces) leading to non-vanishing related commutator and the Heisenberg uncertainty principle

b. the Dirac function
handicap: Dirac (delta) function regularity depends from the space dimension (due to the Sobolev embedding theorem)

3. An alternative mathematical framework
a. A separable distributional (quantum state) Hilbert space H(-1/2) with slightly better regularity than Delta function Hilbert space (independently from space dimension n and valid for all cases n), where L(2)=H(0) test space is a closed sub-space of it. In other words, Dirac's Location Operator is replaced by the orthogonal projection from H(-1/2) Hilbert space onto test space H(0)

b. The standard derivative definition (momentum operator) is replaced by a Calderon-Zygmund (convolution, singular integral) PDO of order 1. In other words, Schrödinger's momentum Operator is replaced the orthogonal projection of the Hilbert space H(1/2) onto the test space H(0)

c. The Dirac function concept (H(0)-inner product of a "function" and its related Fourier transform) is replaced by the inner product of an element of separable distributional Hilbert space and its dual element of the corresponding domain of the momentum operator.

Rational

The proposed mathematical framework above is supposed to provide a truly infinitesimal geometry (H. Weyl). A physical interpretation could be about "rotating differentials" ("quantum fluctuations"), which corresponds mathematically to Leibniz's concept of monads. Its mathematical counterpart are the ideal points (or hyper-real numbers). This leads to non-standard analysis, whereby the number field has same cardinality than the real numbers. It is "just" the Archimedian principle which is no longer valid. This looks like a cheap prize to be paid, especially as hyper-real numbers might provide at least a proper mathematical language for the "Big Bang" initial value "function" and its related Einstein-Hilbert action functional.Looking on hyper-real numbers from the "real" number perspective one must admit to classify the term "real" as a contraction in itself, if it is understood as real. Already the existence of each irrational number (not only the transcendental numbers; and the cardinality of the irrational numbers is different from the rational numbers) is ensured by an axiom, "only", i.e. the "empty space" between two rational numbers is filled with infinite irrational numbers with same cardinaility as the field of real numbers itself, i.e. with multiple "universes". The difference of real numbers to hyper-real numbers is "just" the fact that there are additionally infinite small and large numbers "existent", ensured "just" by a second axiom.

Some more details

We propose a fractional (energy) Hilbert space H(1/2), which already  plays an elegant role in universal Teichmüller theory. It is also related to the bounded variation functions. Ist dual space with respect to the L(2) Lebesgue Hilbert space is the H(-1/2) Hilbert space. The latter one is the proposed quantum state Hilbert space. While the Hermite polynomials (or it Hilbert transforms) build an orthogonal system of the Hilbert space L(2)=H(0) (and related discrete energy spectrum) the basis of the Hilbert space H(-1/2) requires an additional eigenfunction with continuous spectrum. This "eigen-pair" is proposed to be a model for the dark energy model, given by the common (additional) root operator of the ladder "symmetric" operators ("Erzeugungs- und Vernichtungs-operatoren"; "Bosonische und Fermionische Kletteroperatoren"). By this the "symmetry" theory is also anticipated, as the current particles zoo ("materialized" in H(0) Hilbert space) has all the time the same symmetry partner (field), i.e.  the "eigen-function" with continuous spectrum, which spans the closed sub-space H(-1/2)-H(0).

The integral of all frequencies of the proposed harmonic quantum oscillator model is finite (which is not true for the current model (!)), while the Heisenberg uncertainty relation is still valid in the distributional Hilbert space, while allowing discrete momentum-location measurements in sub-space H(0). The "measurement" Hilbert space (which is identical to the statistics modelling Hilbert space) can be interpreted as projections from the H(-1/2) (state) space to its sub-space H(0).

At the end, this mathematical model is claimed to enable a new quantum gravity model replacing complex (not sufficient) mathematical models (e.g. differentiable manifolds with dimensions greater than 10, M-Theory, (Super) String theory, loop quantum gravity, all of them w/o any physical interpretations, by a (at the end, 4 dimensional Minkowski-like) Hilbert space providing not only a metric (exterior differentials), but also a geometry (with inner product). It's still beyong human imagination and open for corresponding physical interpretations, but providing a consistent mathematical model (and therefore an appropriate language) combining the "very large" with the "very small" (R. Penrose).

Along with the alternative Hilbert space  H(-1/2), as a model for the quantum states two additional conceptual changes are proposed to apply the same Hilbert space  alternatively to the current gravity theory framework (differentiable manifolds & affine connexions).

1. Already for the space dimension n=1 the Dirac Delta „function“ is not an element of the (newly proposed quantum state) Hilbert space H(-1/2). This is due to the Sobolev embedding theorem. Therefore, the H(-1/2) Hilbert space concept does not require the Dirac Delta „function“ concept anymore and the Hilbert space extention from H(0) to H(-1/2) enables an alternative wave package concept (with regularity requirements independently from the space dimension). At the same time the model also enables an alternative interpretation of the Neutrinos and their relationship/interaction with Fermions and Baryons. At the same time the concept enables an alternative to current symmetry breaking concept to explain the generation of matter in the early phase of the universe, where energy is required to generate matter w/o violating energy conservation laws out of (massless) photons. Mathematically speaking this is enabled by the compact embedding of the quantum state space H(-1/2) into H(0), which is compactly embedded into the energy space H(1/2).

2. Einstein’s field equations are based on the concept of differentiable manifolds and physical terms are described (indirectly) by vector fields. In case scalar fields would exist this enables direct interpretation/verification of observations and measurements with the mathematical model. The standard scalar field are the real numbers, whereby the term „real“ includes also the irrational numbers and its subset, the transcendental numbers. Ordered fields that have infinitesimal elements are called non-Archimedian. As the distance of two real numbers cannot be infinitely small, G. W. Leibniz argued that the theory of infinitesimals implies the introduction of ideal numbers (monads). This lead to the Non-standard analysis resp. to the concept of hyperreal fields. The differentials (1-forms) can also be brought into relationship to the Hilbert space H(-1/2).

Nota bene

The classical Yang-Mills theory is a generalization of the Maxwell theory of electromagnetism where the chromo-electromagnetic field itself carries charges.

As a classical field theory it has solutions which travel at the speed of light so that its quantum version should describe massless particles (gluons). However, the postulated phenomenon of color confinement permits only bound states of gluons, forming massive particles. This is the mass gap. Another aspect of confinement is asymptotic freedom which makes it conceivable that quantum Yang-Mills theory exists without restriction to low energy scales. The problem is to establish rigorously the existence of the quantum Yang-Mills theory and a mass gap.

Identifiying "fluids" or "sub-atomic particles" not with real numbers (scalar field, I. Newton), but with hyper-real numbers (G. W. Leibniz) enables a truly infinitesimal (geometric) distributional Hilbert space framework (H. Weyl) which corresponds to the Teichmüller theory, the Bounded Mean Oscillation (BMO) and the Harmonic Analysis theory. The distributional Hilbert scale framework enables the full power of spectral theory, while still keeping the standard L(2)=H(0)-Hilbert space as test space to "measure" particles' locations. At the same time, the Ritz-Galerkin (energy or operator norm minimization) method and its counterpart, the methods of Trefftz/Noble to solve PDE by complementary variational principles (A. M. Arthurs, K. Friedrichs, L. B. Rall, P. D. Robinson, W. Velte) w/o anticipating boundary values) enables an alternative "quantization" method of PDE models (P. Ehrenfest), e.g. being applied to the Wheeler-de-Witt operator.
