Gauge field theory approach to spin transport in a 2D electron gas
B. Berche, N. Bolivar, A. Lopez +1
We discuss the Pauli Hamiltonian including the spin-orbit interaction within an U(1) x SU(2) gauge theory interpretation, where the gauge symmetry appears to be broken. This interp…
Two electron entanglement enhancement by an inelastic scattering process
A. Lopez, V. M. Villalba, E. Medina
In order to assess inelastic effects on two fermion entanglement production, we address an exactly solvable two-particle scattering problem where the target is an excitable scatter…
Fermion propagator for QED_3 in the IR domain
C. D. Fosco, A. Lopez
We evaluate the fermion propagator in parity-conserving QED_3 with N flavours, in the context of an IR domain approximation. This provides results which are non-perturbative in the…
Currents and correlations in Luttinger liquids and carbon nanotubes at finite temperature and size: a bosonization study
J. -S. Caux, A. Lopez, D. Suppa
We consider problems of one dimensional interacting fermions confined to a finite size, multichannel geometry. Concentrating on Luttinger liquids and carbon nanotubes, we use nontr…
Noncommutative effective theory of vortices in a complex scalar field
C. D. Fosco, A. Lopez
We derive a noncommutative theory description for vortex configurations in a complex field in 2+1 dimensions. We interpret the Magnus force in terms of the noncommutativity, and ob…
Induced commutative Chern-Simons term from noncommutativity in planar systems
M. L. Ciccolini, C. D. Fosco, A. Lopez
We test the consistency of the use of a noncommutative theory description for charged particles in a strong magnetic field, by deriving the induced Chern-Simons (CS) term for an ex…
