The weakly disordered 2D electron gas in a magnetic field
N. Bralic, R. M. Cavalcanti, C. A. A. de Carvalho +1
We study a relativistic two-dimensional free electron gas in the presence of a uniform external magnetic field and a random static scalar potential. We compute the expectation valu…
On the Quantization of the Abelian Chern-Simons Coefficient at Finite Temperature
N. Bralic, C. D. Fosco, F. A. Schaposnik
We show that when the Abelian \CS\ theory coupled to matter fields is quantized in a vacuum with non vanishing magnetic flux (or electric charge), the requirement of gauge invarian…
Bosonization of Three Dimensional Non-Abelian Fermion Field Theories
Ninoslav Brali{ć}, Eduardo Fradkin, Virginia Manias +2
We discuss bosonization in three dimensions of an massive Thirring model in the low-energy regime. We find that the bosonized theory is related (but not equal) to Y…
Thermodynamics of Relativistic Fermions with Chern-Simons Coupling
N. Bralic, D. Cabra, F. A. Schaposnik
We study the thermodynamics of the relativistic Quantum Field Theory of massive fermions in three space-time dimensions coupled to an Abelian Maxwell-Chern-Simons gauge field. We e…
A Generalized ``Surfaceless'' Stokes' Theorem
N. Bralic
We derive a generalized Stokes' theorem, valid in any dimension and for arbitrary loops, even if self intersecting or knotted. The generalized theorem does not involve an auxiliary…
