A bstract We consider the conformal field theory of N complex massless scalars in 2+ 1
dimensions, coupled to a U (N) Chern-Simons theory at level k. This theory has a't Hooft …

An effective quantum field theory description of graphene in the ultrarelativistic regime is
given by reduced quantum electrodynamics (QED) also known as pseudo QED also known …

The strong time-reversal symmetric topological insulator in three space dimensions features
gapless surface states in the form of massless Dirac fermions. We study these surface states …

Using the bosonization approach, we study fermionic systems with a nonlinear dispersion
relation in dimension d>~ 2. We explicitly show how the band curvature gives rise to …

Using bosonization techniques for (2+ 1) D systems, we show that the transverse
conductance for a system with general current interactions, when measured between perfect …

We explore here the issue of duality versus spectrum equivalence in dual theories
generated through the master action approach. Specifically we examine a generalized self …

We show that the conductance of a one-dimensional, finite charge-density-wave system of
the incommensurate type is not renormalized at low temperatures and depends solely on …

In this paper we study in detail the equivalence of the recently introduced Born–Infeld self-
dual model to the Abelian Born–Infeld–Chern–Simons model in 2+ 1 dimensions. We first …

We study the consequences of including parity preserving matter for the effective dual theory
corresponding to compact QED3; in particular, we focus on the effect of that contribution on …

The coefficient of the Chern–Simons term in the effective action for massive Dirac fermions
in three dimensions is computed by using the point-splitting regularization method. We show …
