Implementing supersymmetric dynamics in ultracold atom systems

Autor: Lahrz, M., Weitenberg, C., Mathey, L.

Publikováno v: Phys. Rev. A 96, 043624 (2017)

Supersymmetric systems derive their properties from conserved supercharges which form a supersymmetric algebra. These systems naturally factorize into two subsystems, which, when considered as individual systems, have essentially the same eigenenergi

Exotic roton excitations in quadrupolar Bose-Einstein condensates

Autor: Lahrz, M., Lemeshko, Mikhail, Mathey, L.

Publikováno v: New J. Phys. 17 (2015)

We investigate the occurrence of rotons in a quadrupolar Bose-Einstein condensate confined to two dimensions. Depending on the particle density, the ratio of the contact and quadrupole-quadrupole interactions, and the alignment of the quadrupole mome

Detecting quadrupole interactions in ultracold Fermi gases

Autor: Lahrz, M., Lemeshko, Mikhail, Sengstock, Klaus, Becker, Christoph, Mathey, L.

Publikováno v: Phys. Rev. A 89, 043616 (2014)

We propose to detect quadrupole interactions of neutral ultra-cold atoms via their induced mean-field shift. We consider a Mott insulator state of spin-polarized atoms in a two-dimensional optical square lattice. The quadrupole moments of the atoms a

Quantum phases of quadrupolar Fermi gases in coupled one-dimensional systems

Autor: Huang, Wen-Min, Lahrz, M., Mathey, L.

Publikováno v: Phys. Rev. A 89, 013604 (2014)

Following the recent proposal to create quadrupolar gases [S.G. Bhongale et al., Phys. Rev. Lett. 110, 155301 (2013)], we investigate what quantum phases can be created in these systems in one dimension. We consider a geometry of two coupled one-dime
