On-site number statistics of ultracold lattice bosons
Barbara Capogrosso-Sansone, Evgeny Kozik, Nikolay Prokof'ev +1
We study on-site occupation number fluctuations in a system of interacting bosons in an optical lattice. The ground-state distribution is obtained analytically in the limiting case…
The Fermi-Hubbard model at unitarity
Evgeni Burovski, Nikolay Prokof'ev, Boris Svistunov +1
We simulate the dilute attractive Fermi-Hubbard model in the unitarity regime using a diagrammatic determinant Monte Carlo algorithm with worm-type updates. We obtain the dependenc…
Worm Algorithm and Diagrammatic Monte Carlo: A New Approach to Continuous-Space Path Integral Monte Carlo Simulations
M. Boninsegni, N. V. Prokof'ev, B. V. Svistunov
A detailed description is provided of a new Worm Algorithm, enabling the accurate computation of thermodynamic properties of quantum many-body systems in continuous space, at finit…
The fate of vacancy-induced supersolidity in 4He
Massimo Boninsegni, Anatoly Kuklov, Lode Pollet +3
The supersolid state of matter, exhibiting non-dissipative flow in solids, has been elusive for thirty five years. The recent discovery of a non-classical moment of inertia in soli…
Non-Positive Rule for Continuous Phase Transition Lines
Nikolay Prokof'ev, Boris Svistunov
This paper has been withdrawn by the authors, due to a possible flaw in its logic. Namely, it has been taken for granted that the the structure of regular part of Helmholtz free en…
Deconfined criticality, runaway flow in the two-component scalar electrodynamics and weak first-order superfluid-solid transitions
Anatoly Kuklov, Nikolay Prokof'ev, Boris Svistunov +1
We perform a comparative Monte Carlo study of the easy-plane deconfined critical point (DCP) action and its short-range counterpart to reveal close similarities between the two mod…
