Collective oscillations of a Fermi gas near a Feshbach resonance
Theja N. De Silva, Erich J. Mueller
A sum rule approach is used to calculate the zero temperature oscillation frequencies of a two component trapped atomic Fermi gas in the BCS-Bose Einstein condensation crossover re…

Dynamically generated dimension reduction and crossover in a spin orbital model
Theja. N. De Silva, Michael Ma, Fu Chun Zhang
We study a spin orbital model in which the spin-spin interaction couples linearly to the orbital isospin. Fluctuations drive the transition from paramagnetic state to C type ordere…
