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…
Braiding properties of worldline configurations in hardcore lattice bosons
Fabio Lingua, Wei Wang, Liana Shpani +1
In this manuscript, we study braiding properties of worldline configurations for a variety of ground-states of hardcore Bose-Hubbard models in two dimensions. Configurations are co…
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…
Delocalization effects, entanglement entropy and spectral collapse of boson mixtures in a double well
F. Lingua, G. Mazzarella, V. Penna
We investigate the ground-state properties of a two-species condensate of interacting bosons in a double-well potential. Each atomic species is described by a two-space-mode Bose-H…
An Analytic Method for -Expansion involving Resonance and Reduction
M. C. Ipinza, F. Lingua, D. M. Peñafiel +1
In this paper we describe an analytic method able to give the multiplication table(s) of the set(s) involved in an -expansion process (with either resonance or -resonant-re…
Demixing Effects in Mixtures of Two Bosonic Species
F. Lingua, B. Capogrosso-Sansone, M. Guglielmino +1
Motivated by recent experiments on two-component systems, we investigate the ground-state phase diagram of a mixture of two bosonic species by means of path-integral quantum Monte…
