Truncated-Determinant Diagrammatic Monte Carlo for Fermions with Contact Interaction
Evgueni Bourovski, Nikolay Prokof'ev, Boris Svistunov
For some models of interacting fermions the known solution to the notorious sign-problem in Monte Carlo (MC) simulations is to work with macroscopic fermionic determinants; the pri…
Comment on "Phase Diagram of a Disordered Boson Hubbard Model in Two Dimensions"
Nikolay Prokof'ev, Boris Svistunov
We prove that previous claims of observing a direct superfluid-Mott insulator transition in the disordered J-current model are in error because numerical simulations were done for…
Detecting Super-Counter-Fluidity by Ramsey Spectroscopy
Anatoly Kuklov, Nikolay Prokof'ev, Boris Svistunov
Spatially selective Ramsey spectroscopy is suggested as a method for detecting the super-counter-fluidity of two-component atomic mixture in optical lattice.
Commensurate Two-Component Bosons in Optical Lattice: Groundstate Phase Diagram
Anatoly Kuklov, Nikolay Prokof'ev, Boris Svistunov
Two sorts of bosons in an optical lattice at commensurate filling factors can form five stable superfluid and insulating groundstates with rich and non-trivial phase diagram. The s…
Superfluid-Superfluid Phase Transitions in Two-Component Bose System
A. Kuklov, N. Prokof'ev, B. Svistunov
Depending on the Hamiltonian parameters, two-component bosons in an optical lattice can form at least three different superfluid phases in which both components participate in the…
Superfluid--Insulator Transition in Commensurate Disordered Bosonic Systems:Large-Scale Worm-Algorithm Simulations
Nikolay Prokof'ev, Boris Svistunov
We report results of large-scale Monte Carlo simulations of superfluid--insulator transitions in commensurate 2D bosonic systems. In the case of off-diagonal disorder (quantum perc…
