Kondo effect in flux phases
Carlos R. Cassanello, Eduardo Fradkin
We consider a band of fermions in two space dimensions with a flux phase (relativistic) dispersion relation coupled to a local magnetic impurity via an interaction. This mod…
Exact effective action for fermions in one dimension with backscattering at a boundary
Manuel Fuentes, Ana Lopez, Eduardo Fradkin
We report exact results for the partition function for free Dirac fermions on a half line with physically sensible boundary conditions. An exact effective action for general backsc…
Bosonization rules in dimensions
Manuel Fuentes, Ana Lopez, Eduardo Fradkin +1
We derive the bosonization rules for free fermions on a half-line with physically sensible boundary conditions for Luttinger fermions. We use path-integral methods to calculate the…
Bilayers of Chiral Spin States
Carlos Cassanello, Eduardo Fradkin
We study the behavior of two planes of Quantum Heisenberg Antiferromagnet in the regime in which a Chiral Spin Liquid is stabilized in each plane. The planes are coupled by an exch…
