Universality in rotating strongly interacting gases    [PDF]

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.
