Superfluid-supersolid phase transition of elongated dipolar Bose-Einstein condensates at finite temperatures
Juan Sánchez-Baena, Thomas Pohl, Fabian Maucher
We analyze the finite-temperature phase diagram of a dipolar Bose-Einstein condensate confined in a tubular geometry. The effect of thermal fluctuations is accounted for by means of Bogoliubov theory employing the local density approximation. In the considered geometry, the superfluid-supersolid phase transition can be of first and second order. We discuss how the corresponding transition point is affected by the finite temperature of the system. Published by the American Physical Society 2024
