Permutation cycles of hardcore Bose-Hubbard models on square and Kagome lattices
Liana Shpani, Fabio Lingua, Wei Wang +1
In this paper, we study the statistics of permutation cycles of ground-state hardcore lattice bosons described by various two-dimensional Bose-Hubbard-type models on both square an…
Multiworm algorithm quantum Monte Carlo
F. Lingua, B. Capogrosso-Sansone, A. Safavi-Naini +2
We review the path-integral quantum Monte Carlo method and discuss its implementation by multiworm algorithms. We analyze in details the features of the algorithms, and focus our a…
Residual entropy and critical behavior of two interacting boson species in a double well
Fabio Lingua, Andrea Richaud, Vittorio Penna
Motivated by the importance of entanglement and correlation indicators in the analysis of quantum systems, we study the equilibrium and the bipartite residual entropy in a two-spec…
A continuous-variable approach to the spectral properties and quantum states of the two-component Bose-Hubbard dimer
F. Lingua, V. Penna
A bosonic gas formed by two interacting species trapped in a double-well potential features macroscopic localization effects when the interspecies interaction becomes sufficiently…
