Critical behavior of the Ashkin-Teller model with a line defect: a Montecarlo study
G. Duchowney, C. Naón, A. Iucci
We study magnetic critical behavior in the Ashkin-Teller model with an asymmetric defect line. This system is represented by two Ising lattices of spins and interacting thr…
Heat transport through quantum Hall edge states: Tunneling versus capacitive coupling to reservoirs
H. Aita, L. Arrachea, C. Naón +1
We study the heat transport along an edge state of a two-dimensional electron gas in the quantum Hall regime, in contact to two reservoirs at different temperatures. We consider tw…
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…
Spin correlation function in 2D statistical mechanics models with inhomogeneous line defects
Carlos Naón, Marta Trobo
We consider the critical spin-spin correlation function of the 2D Ising model with a line defect which strength is an arbitrary function of position. By using path-integral techniq…
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…
Voltage profile and four terminal resistance of an interacting quantum wire
Liliana Arrachea, Carlos Naón, Mariano Salvay
We investigate the behavior of the four-terminal resistance in a quantum wire described by a Luttinger liquid in two relevant situations: (i) in the presence of a single…
