Path-integral Bosonization of PT symmetric models
C. M. Naón, F. A. Schaposnik
We discuss bosonization of non-Hermitian PT invariant fermion models in space-time dimensions within the path-integral approach in which the generating functionals associated…
Bosonic description of a Tomonaga-Luttinger model with impurities
Victoria Fernandez, Kang Li, Carlos Naon
We extend a recently proposed non-local version of Coleman's equivalence between the Thirring and sine-Gordon models to the case in which the original fermion fields interact with…
Path-integral formulation of backward and umklapp scattering for 1d spinless fermions
V. I. Fernández, C. M. Naón
We present a (1+1)-dimensional fermionic QFT with non-local couplings between currents. This model describes an ensemble of spinless fermions interacting through forward, backward…
Non-local Thirring model at finite-temperature
M. V. Manias, C. M. Naon, M. L. Trobo
We extend a recently proposed non-local and non-covariant version of the Thirring model to the finite-temperature case. We obtain a completely bosonized expression for the partitio…
Field theory approach to one-dimensional electronic systems
Carlos M. Naon
In this talk I describe a recently introduced field-theoretical approach that can be used as an alternative framework to study one-dimensional systems of highly correlated particle…
Equivalent bosonic theory for the massive Thirring model with non-local interaction
Kang Li, Carlos Naon
We study, through path-integral methods, an extension of the massive Thirring model in which the interaction between currents is non-local. By examining the mass-expansion of the p…
