Pair superfluid phases in quasi one dimensional dipolar gases — •Rebecca Kraus1, Krzysztof Biedroń2, Jakub Zakrzewski2,3, and Giovanna Morigi1 — 1Theoretische Physik, Universität des Saarlandes, D-66123 Saarbrücken, Germany — 2Instytut Fizyki imienia Mariana Smoluchowskiego, Uniwersytet Jagielloński, Łojasiewicza 11, 30-048 Kraków, Poland — 3Mark Kac Complex Systems Research Center, Jagiellonian University, Łojasiewicza 11, 30-348 Kraków, Poland
We consider ultracold dipolar bosons in an optical lattice in a quasi-one dimensional geometry. We focus on the stability of pair superfluidity [1,2] as a function of the dipole interaction strength. We discuss the phases also for different power laws, such as van der waals interaction between Rydberg dressed atoms.
