Decoupling Transformations in Path Integral Bosonization
C. D. Fosco, J. C. Le Guillou
We construct transformations that decouple fermionic fields in interaction with a gauge field, in the path integral representation of the generating functional. Those transformatio…
Duality between Topologically Massive and Self-Dual models
J. C. Le Guillou, E. F. Moreno, C. Nunez +1
We show that, with the help of a general BRST symmetry, different theories in 3 dimensions can be connected through a fundamental topological field theory related to the classical…
Critical Exponents of the pure and random-field Ising models
Th. Jolicoeur, J. C. Le Guillou
We show that current estimates of the critical exponents of the three-dimensional random-field Ising model are in agreement with the exponents of the pure Ising system in dimension…
On three dimensional bosonization
J. C. Le Guillou, E. Moreno, C. Nuñez +1
We discuss Abelian and non-Abelian three dimensional bosonization within the path-integral framework. We present a systematic approach leading to the construction of the bosonic ac…
Non Abelian Bosonization in Two and Three Dimensions
J. C. Le Guillou, E. Moreno, C. Nunez +1
We discuss non-Abelian bosonization of two and three dimensional fermions using a path-integral framework in which the bosonic action follows from the evaluation of the fermion det…
On the Electric Charge of Monopoles at Finite Temperature
J. C. Le Guillou, F. A. Schaposnik
We calculate the electric charge at finite temperature for non-Abelian monopoles in spontaneously broken gauge theories with a CP violating -term. A careful treatment of dyo…
