Non local Thirring model with backward and umklapp interactions
V. I. Fernández, C. A. Iucci, C. M. Naón
We extend a non local and non covariant version of the Thirring model in order to describe a many-body system with backward and umklapp scattering processes. We express the vacuum…
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…
Functional integral approach to multipoint correlators in 2d critical systems
V. I. Fernandez, C. M. Naon
We extend a previously developed technique for computing spin-spin critical correlators in the 2d Ising model, to the case of multiple correlations. This enables us to derive Kadan…
