Classical brackets for dissipative systems
Giuseppe Bimonte, Giampiero Esposito, Giuseppe Marmo +1
We show how to write a set of brackets for the Langevin equation, describing the dissipative motion of a classical particle, subject to external random forces. The method does not…
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…
Peierls Brackets: from Field Theory to Dissipative Systems
Giuseppe Bimonte, Giampiero Esposito, Giuseppe Marmo +1
A review is given of the Peierls bracket formalism in field theory, and of a new, recent application of this concept to the analysis of dissipative systems.
Spacetime Noncommutativity and Antisymmetric Tensor Dynamics in the Early Universe
Elisabetta Di Grezia, Giampiero Esposito, Agostino Funel +2
This paper investigates the possible cosmological implications of the presence of an antisymmetric tensor field related to a lack of commutatitivity of spacetime coordinates at the…
A Class of Renormalization Group Invariant Scalar Field Cosmologies
A. Bonanno, G. Esposito, C. Rubano
We present a class of scalar field cosmologies with a dynamically evolving Newton parameter and cosmological term . In particular, we discuss a class of solutions which are…
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…
