Quantum Hall Superfluids in Topological Insulator Thin Films
Dagim Tilahun, Byounghak Lee, E. M. Hankiewicz +1
Three-dimensional topological insulators have protected Dirac-cone surface states. In this paper we propose magnetic field induced topological insulator thin film ordered states in…

A Quantum Theory of Cold Bosonic Atoms in Optical Lattices
Dagim Tilahun, R. A. Duine, A. H. MacDonald
Ultracold atoms in optical lattices undergo a quantum phase transition from a superfluid to a Mott insulator as the lattice potential depth is increased. We describe an approximate…
