Classical versus quantum structures: the case of pyramidal molecules
Carlo Presilla, Giovanni Jona-Lasinio, Cristina Toninelli
In a previous paper we proposed a model to describe a gas of pyramidal molecules interacting via dipole-dipole interactions. The interaction modifies the tunneling properties betwe…
Environment induced localization and superselection rules in a gas of pyramidal molecules
Giovanni Jona-Lasinio, Carlo Presilla, Cristina Toninelli
We propose a model to describe a gas of pyramidal molecules interacting via dipole-dipole interactions. A cooperative effect induced by the interaction modifies the tunneling prope…
An exact representation of the fermion dynamics in terms of Poisson processes
Matteo Beccaria, Carlo Presilla, Gian Fabrizio De Angelis +1
We present a simple derivation of a Feynman-Kac type formula to study fermionic systems. In this approach the real time or the imaginary time dynamics is expressed in terms of the…
