Entanglement in composite free-fermion systems [PDF]
, 2015 We consider fermionic chains where the two halves are either metals with different bandwidths or a metal and an insulator. Both are coupled together by a special bond.

Bosonic Analogue of Dirac Composite Fermi Liquid [PDF]
, 2016 We introduce a particle-hole-symmetric metallic state of bosons in a magnetic field at odd-integer filling. This state hosts composite fermions whose energy dispersion features a quadratic band touching and corresponding $2\pi$ Berry flux protected by ...

Composite fermi liquids in the lowest Landau level [PDF]
, 2016 We study composite fermi liquid (CFL) states in the lowest Landau level (LLL) limit at a generic filling $\nu = \frac{1}{n}$. We begin with the old observation that, in compressible states, the composite fermion in the lowest Landau level should be ...

Microscopic Realization of 2-Dimensional Bosonic Topological Insulators [PDF]
, 2014 It is well known that a Bosonic Mott insulator can be realized by condensing vortices of a bo- son condensate. Usually, a vortex becomes an anti-vortex (and vice-versa) under time reversal symmetry, and the condensation of vortices results in a trivial ...
