Classical modelling of a lossy Gaussian bosonic sampler
M. V. Umanskii, A. N. Rubtsov
Gaussian boson sampling (GBS) is considered a candidate problem for demonstrating quantum advantage. We propose an algorithm for approximate classical simulation of a lossy GBS ins…

Landau Free Energy of small clusters beyond mean field approach
S. Semenov, A. N. Rubtsov
The Landau Free Energy determines the landscape of order parameter fluctuations that occur in a physical system at thermal equilibrium and, in particular, characterizes the critica…
