Unconventional interaction between vortices in a polarized Fermi gas
Vladimir M. Stojanovic, W. Vincent Liu, Yong Baek Kim
Recently, a homogeneous superfluid state with a single gapless Fermi surface was predicted to be the ground state of an ultracold Fermi gas with spin population imbalance in the re…

Superfluid-Insulator transitions of bosons on Kagome lattice at non-integer fillings
K. Sengupta, S. V. Isakov, Yong Baek Kim
We study the superfluid-insulator transitions of bosons on the Kagome lattice at incommensurate filling factors f=1/2 and 2/3 using a duality analysis. We find that at f=1/2 the bo…

One-dimensional itinerant ferromagnets with Heisenberg symmetry and the ferromagnetic quantum critical point
K. Sengupta, Yong Baek Kim
We study one-dimensional itinerant ferromagnets with Heisenberg symmetry near a ferromagnetic quantum critical point. It is shown that the Berry phase term arises in the effective…
