Effective Chern-Simons Theories of Pfaffian and Parafermionic Quantum Hall States, and Orbifold Conformal Field Theories
Eduardo Fradkin, Marina Huerta, Guillermo Zemba
We present a pure Chern-Simons formulation of families of interesting Conformal Field Theories describing edge states of non-Abelian Quantum Hall states. These theories contain two…
Nodal quasi-particles and coexisting orders in striped superconductors
M. Granath, V. Oganesyan, S. A. Kivelson +2
We study the properties of a quasi-one dimensional superconductor which consists of an alternating array of two inequivalent chains. This model is a simple charicature of a locally…
Fractional quantum Hall junctions and two-channel Kondo models
N. Sandler, E. Fradkin
A mapping between fractional quantum Hall (FQH) junctions and the two-channel Kondo model is presented. We discuss in detail this relation for the particular case of a junction of…
Antiferromagnetic spin ladders effectively coupled by one-dimensional electron liquids
W. Vincent Liu, Eduardo Fradkin
We study a model of the stripe state in strongly correlated systems consisting of an array of antiferromagnetic spin ladders, each with legs, coupled to each other throug…
Effective field theory for the bulk and edge states of quantum Hall states in unpolarized single layer and bilayer systems
Ana Lopez, Eduardo Fradkin
We present an effective theory for the bulk Fractional Quantum Hall states in spin-polarized bilayer and spin-1/2 single layer two-dimensional electron gases (2DEG) in high magneti…
Quantum Theory of the Smectic Metal State in Stripe Phases
Victor J. Emery, Eduardo Fradkin, Steven A. Kivelson +1
We present a theory of the electron smectic fixed point of the stripe phases of doped layered Mott insulators. We show that in the presence of a spin gap three phases generally ari…
