Transient and finite size effects in transport properties of a quantum wire
Mariano Salvay, Aníbal Iucci, Carlos Naón
We study the time-dependent backscattered current produced in a quantum wire when a local barrier is suddenly switched on. Previous investigations are improved by taking into accou…
Transient effects in the backscattered current of a Luttinger liquid
Mariano J. Salvay, Hugo A. Aita, Carlos M. Naón
We study the backscattered current in a Luttinger liquid in the presence of a point like weak impurity switched on at finite time, taking into account finite-temperature effects. W…
Effect of nonadiabatic switching of dynamic perturbations in 1d Fermi systems
Carlos M. Naón, Mariano J. Salvay, Marta L. Trobo
We study a two-dimensional fermionic QFT used to model 1D strongly correlated electrons in the presence of a time-dependent impurity that drives the system out of equilibrium. In c…
Friedel oscillations in a Luttinger liquid with long-range interactions
Victoria I. Fernández, Carlos M. Naón
We introduce a path-integral approach that allows to compute charge density oscillations in a Luttinger liquid with impurities. We obtain an explicit expression for the envelope of…
Exact electronic Green functions in a Luttinger liquid with long-range interactions
Aníbal Iucci, Carlos Naón
We compute the 2-point (equal-time) electronic Green function in a Tomonaga-Luttinger system with long-range electron-electron interactions. We obtain an analytical expression for…
Field-theory computation of charge-density oscillations in a Tomonaga-Luttinger model with impurities
Victoria I. Fernández, Carlos M. Naón
We compute the charge-density oscillations in a Tomonaga-Luttinger model with impurities for a short-range electron-electron potential.
