A New Spectral Cancellation in Quantum Gravity
Giampiero Esposito, Guglielmo Fucci, Alexander Yu. Kamenshchik +1
A general method exists for studying Abelian and non-Abelian gauge theories, as well as Euclidean quantum gravity, at one-loop level on manifolds with boundary. In the latter case,…
Euclidean Quantum Gravity in Light of Spectral Geometry
Giampiero Esposito
A proper understanding of boundary-value problems is essential in the attempt of developing a quantum theory of gravity and of the birth of the universe. The present paper reviews…
On the behaviour of a rigid Casimir cavity in a gravitational field
Giuseppe Bimonte, Enrico Calloni, Luciano Di Fiore +3
A detailed investigation is presented of the energy-momentum tensor approach to the evaluation of the force acting on a rigid Casimir cavity in a weak gravitational field. Such a f…
Peierls Brackets in Theoretical Physics
Giampiero Esposito, Giuseppe Marmo, Cosimo Stornaiolo
Peierls brackets are part of the space-time approach to quantum field theory, and provide a Poisson bracket which, being defined for pairs of observables which are group invariant,…
On the Riemann Function and Irregular Singular Points for Axisymmetric Black Hole Collisions at the Speed of Light
Giampiero Esposito, Cosimo Stornaiolo
The news function providing some relevant information about angular distribution of gravitational radiation in axisymmetric black hole collisions at the speed of light had been eva…
A new application of non-canonical maps in quantum mechanics
Giampiero Esposito
A proof is given that an invertible and a unitary operator can be used to reproduce the effect of a q-deformed commutator of annihilation and creation operators. In other words, th…
