The stability of the fractional quantum Hall effect in topological insulators
, 2011 With the recent observation of graphene-like Landau levels at the surface of topological insulators, the possibility of fractional quantum Hall effect, which is a fundamental signature of strong correlations, has become of interest. Some experiments have

Effective field theories for topological insulators by functional bosonization
, 2013 Effective field theories that describes the dynamics of a conserved U(1) current in terms of "hydrodynamic" degrees of freedom of topological phases in condensed matter are discussed in general dimension $D=d+1$ using the functional bosonization ...

Dog Wool Microparticles/Polyurethane Composite for Thermal Insulation [PDF]
Polymers, 2020 A polyurethane (PU)-based eco-composite foam was prepared using dog wool fibers as a filler. Fibers were acquired from pet shops and alkaline treated prior to use. The influence of their incorporation on the PU foams’ morphological, thermal, and mechanical properties was investigated.

Effective hydrodynamic field theory and condensation picture of topological insulators
, 2015 While many features of topological band insulators are commonly discussed at the level of single-particle electron wave functions, such as the gapless Dirac spectrum at their boundary, it remains elusive to develop a {\it hydrodynamic} or {\it collective}

Quantum oscillations in insulators with neutral Fermi surfaces
, 2017 We develop a theory of quantum oscillations in insulators with an emergent fermi sea of neutral fermions minimally coupled to an emergent $U(1)$ gauge field. As pointed out by Motrunich (Phys. Rev.
