Ground state of many-body lattice systems via a central limit theorem
Carlo Presilla, Massimo Ostilli
We review a novel approach to evaluate the ground-state properties of many-body lattice systems based on an exact probabilistic representation of the dynamics and its long time app…
Ground state of many-body lattice systems: an analytical probabilistic approach
Massimo Ostilli, Carlo Presilla
On the grounds of a Feynman-Kac--type formula for Hamiltonian lattice systems we derive analytical expressions for the matrix elements of the evolution operator. These expressions…
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…
Stationary states of Bose-Einstein condensates in single- and multi-well trapping potentials
Roberto D'Agosta, Boris A. Malomed, Carlo Presilla
The stationary solutions of the Gross-Pitaevskii equation can be divided in two classes: those which reduce, in the limit of vanishing nonlinearity, to the eigenfunctions of the as…
Comment on the paper ``Decoherence and the theory of continuous quantum measurements'', by M. B. Mensky, Phys. Usp. 41, 923 (1998), arXiv:quant-ph/9812017v2
Roberto Onofrio, Carlo Presilla
In quant-ph/9812017v2 M.B. Mensky reviewed our application of the restricted path integral approach to quantum measurements of energy. In this comment we point out that Mensky's as…
