Evidence from on-site atom number fluctuations for a quantum Berezinskii-Kosterlitz-Thouless transition in the one-dimensional Bose-Hubbard model
Mateusz Łącki, Bogdan Damski
We study the one-dimensional Bose-Hubbard model describing the superfluid-Mott insulator quantum phase transition of cold atoms in optical lattices. We show that derivatives of the…

Critical points of the three-dimensional Bose-Hubbard model from on-site atom number fluctuations
Oskar A. Prośniak, Mateusz Łącki, Bogdan Damski
We discuss how positions of critical points of the three-dimensional Bose-Hubbard model can be accurately obtained from variance of the on-site atom number operator, which can be e…
