Effects of Bending modes on the quantum statistics of self-assembled chains of polar molecules — •Jörg Duhme, Michael Klawunn, and Luis Santos — Institut für Theoretische Physik, Leibniz Universität Hannover, Appelstr. 2, D-30167, Hannover, Germany

Under certain circumstances quantum gases caught in harmonical traps can form layers. Dipolar gases are needed for a long-range interaction between different layers. In dilute gases this anisotropic interaction causes the formation of chains (filaments) of dipolar molecules [1]. We studied the effect of the bending modes of these filaments on the quantum statistics of the whole system made of several layers. Furthermore we investigated the effect of the bending modes on the critical temperature of the system to form a BEC of chains. The bending modes have important consequences for the critical temperature as well as for the quantum statistics of the whole system.
