Theory of decay of superfluid turbulence in the low-temperature limit
E. V. Kozik, B. V. Svistunov
We review the theory of relaxational kinetics of superfluid turbulence--a tangle of quantized vortex lines--in the limit of very low temperatures when the motion of vortices is con…
Diagrammatic Monte Carlo
Kris Van Houcke, Evgeny Kozik, Nikolay Prokof'ev +1
Diagrammatic Monte Carlo (DiagMC) is a numeric technique that allows one to calculate quantities specified in terms of diagrammatic expansions, the latter being a standard tool of…
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…
Vortex-Phonon Interaction in the Kosterlitz-Thouless Theory
Evgeny Kozik, Nikolay Prokof'ev, Boris Svistunov
The "canonical" variables of the Kosterlitz-Thouless theory--fields and , generally believed to stand for vortices and phonons (or their XY equivalents,…
