Finite-temperature phase transition in a homogeneous one-dimensional gas of attractive bosons: Supporting data Open Access

Supporting data for arxiv:1610.09070 https://arxiv.org/abs/1610.09070. Abstract from paper: In typical one-dimensional models the Mermin-Wagner theorem forbids long range order, thus preventing finite-temperature phase transitions. We find a finite-temperature phase transition for a homogeneous system of attractive bosons in one dimension. The low-temperature phase is characterized by a quantum bright soliton without long range order; the high-temperature phase is a free gas. Numerical calculations for finite particle numbers show a specific heat scaling as N2, consistent with a vanishing transition region in the thermodynamic limit.
