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…
Four-terminal resistance of an interacting quantum wire with weakly invasive contacts
Hugo Aita, Liliana Arrachea, Carlos Naón
We analyze the behavior of the four-terminal resistance, relative to the two-terminal resistance of an interacting quantum wire with an impurity, taking into account the invasivene…
Critical behavior of the spin correlation function in Ashkin-Teller and Baxter models with a line defect
Carlos Naón
We consider the critical spin-spin correlation function of the Ashkin-Teller and Baxter models. By using path-integral techniques in the continuum description of these models in te…
Conformal properties of 1D quantum systems with long-range interactions
Carlos M. Naón, Mariano J. Salvay, Marta L. Trobo
We investigate conformal properties of a one-dimensional quantum system with a long-range, Coulomb-like potential of the form , with . We compute the conforma…
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…
