Violation of the Wiedemann-Franz Law in a Large-N Solution of the t-J Model
A. Houghton, S. Lee, J. B. Marston
We show that the Wiedemann-Franz law, which holds for Landau Fermi liquids, breaks down in a large-n treatment of the t-J model. The calculated ratio of the in-plane thermal and el…
Thermal conductivity in the vortex state of d-wave superconductors
I. Vekhter, A. Houghton
We present the results of a microscopic calculation of the longitudinal thermal conductivity of quasiparticles, , in a 2D d-wave superconductor in the vortex state. Our app…
Multidimensional Bosonization
A. Houghton, H. -J. Kwon, J. B. Marston
Bosonization of degenerate fermions yields insight both into Landau Fermi liquids, and into non-Fermi liquids. We begin our review with a pedagogical introduction to bosonization,…
Quasiclassical Approach to Transport in the Vortex State and the Hall Effect
A. Houghton, I. Vekhter
We derive generalized quasiclassical transport equations which include the terms responsible for the Hall Effect in the vortex state of a clean type-II superconductor, and calculat…
Hall Effect in the mixed state of moderately clean superconductors
I. Vekhter, A. Houghton
The Hall conductivity in the mixed state of a clean () type-II s-wave superconductor is determined from a microscopic calculation within a quasiclassical approximation.…
Theory of Fermion Liquids
H. -J. Kwon, A. Houghton, J. B. Marston
We develop a general theory of fermion liquids in spatial dimensions greater than one. The principal method, bosonization, is applied to the cases of short and long range longitudi…
