Bethe free-energy approximations for disordered quantum systems
I. Biazzo, A. Ramezanpour
Given a locally consistent set of reduced density matrices, we construct approximate density matrices which are globally consistent with the local density matrices we started from…

On the performance of a cavity method based algorithm for the Prize-Collecting Steiner Tree Problem on graphs
Indaco Biazzo, Alfredo Braunstein, Riccardo Zecchina
We study the behavior of an algorithm derived from the cavity method for the Prize-Collecting Steiner Tree (PCST) problem on graphs. The algorithm is based on the zero temperature…

Low-temperature excitations within the Bethe approximation
I. Biazzo, A. Ramezanpour
We propose the variational quantum cavity method to construct a minimal energy subspace of wave vectors that are used to obtain some upper bounds for the energy cost of the low-tem…
