Operator Gauge Symmetry in QED
Symmetry, Integrability and Geometry: Methods and Applications, 2006 In this paper, operator gauge transformation, first introduced by Kobe, is applied to Maxwell's equations and continuity equation in QED. The gauge invariance is satisfied after quantization of electromagnetic fields.

Nonsymmetric Ornstein-Uhlenbeck semigroup as second quantized operator
Kyoto Journal of Mathematics, 1996 This work deals with properties of the semigroup related to the Ornstein-Uhlenbeck operator \[ L\phi(x)=\textstyle{{1\over 2}}\text{ Tr }QD^2\phi(x)+ \langle Ax,D\phi(x)\rangle \] in a real separable Hilbert space \(H\). We assume that \(A\) is the generator of a \(C_0\)-semigroup \(S(t)\), \(t\geq 0\), of bounded operators on \(H\), \(Q\) is bounded ...

Quantum Einsteinian cubic cosmology
European Physical Journal C: Particles and FieldsWe study Cosmological Einsteinian Cubic Gravity (CECG) in the context of minisuperspace quantum cosmology. CECG is a modification of Einstein’s gravity by cubic curvature terms that contribute non-trivially to the dynamics of FRW backgrounds, while the ...

Operational quantization of dynamical systems subject to second class constraints
Nuclear Physics B, 1987 Abstract An operational version is proposed for the generalized canonical quantization method of dynamical systems subject to second class constraints. New generating equations are formulated for the generalized algebra of constraints and for the unitarizing hamiltonian.

The Noncommutative Doplicher-Fredenhagen-Roberts-Amorim Space
Symmetry, Integrability and Geometry: Methods and Applications, 2010 This work is an effort in order to compose a pedestrian review of the recently elaborated Doplicher, Fredenhagen, Roberts and Amorim (DFRA) noncommutative (NC) space which is a minimal extension of the DFR space.

Lévy–Ornstein–Uhlenbeck transition semigroup as second quantized operator
Journal of Functional Analysis, 2011 Let \(\mu\) be an invariant measure for the transition semigroup \((P_t)\) of the Markov family defined by the Ornstein-Uhlenbeck type equation \(dX=AX\,dt+dL\) on a Hilbert space \(E\) driven by a Lévy process \(L\). The author shows that, for any \(t\geq 0\), \(P_t\) considered on \(L^2(\mu )\) is a second quantized operator on the Poisson Fock space
