ItemUniversality in rotating strongly interacting gasesMulkerin, BC ; Bradly, CJ ; Quiney, HM ; Martin, AM (AMER PHYSICAL SOC, 2012-05-24)We analytically determine the properties of two interacting particles in a harmonic trap subject to a rotation or a uniform synthetic magnetic field, where the spherical symmetry of the relative Hamiltonian is preserved. Thermodynamic quantities such as the entropy and energy are calculated via the second order quantum cluster expansion. We find that in the strongly interacting regime the energy is universal, however the entropy changes as a function of the rotation or synthetic magnetic field strength.

ItemUniversality and itinerant ferromagnetism in rotating strongly interacting Fermi gasesMulkerin, BC ; Bradly, CJ ; Quiney, HM ; Martin, AM (AMER PHYSICAL SOC, 2012-11-30)We analytically determine the properties of three interacting fermions in a harmonic trap subject to an external rotation. Thermodynamic quantities such as the entropy and energy are calculated from the third order quantum virial expansion. By parameterizing the solutions in the rotating frame we find that the energy and entropy are universal for all rotations in the strongly interacting regime. Additionally, we find that rotation suppresses the onset of itinerant ferromagnetism in strongly interacting repulsive three-body systems.
