Defining the effective temperature of a quantum driven system from current-current correlation functions
Alvaro Caso, Liliana Arrachea, Gustavo S. Lozano
We calculate current-current correlation functions and find an expression for the zero-frequency noise of multiterminal systems driven by harmonically time-dependent voltages withi…
Chiral heat transport in driven quantum Hall and quantum spin Hall edge states
Liliana Arrachea, Eduardo Fradkin
We consider a model for an edge state of electronic systems in the quantum Hall regime with filling and in the quantum spin Hall regime. In both cases the system is in contac…
Current-induced switching in transport through anisotropic magnetic molecules
Niels Bode, Liliana Arrachea, Gustavo S. Lozano +2
Anisotropic single-molecule magnets may be thought of as molecular switches, with possible applications to molecular spintronics. In this paper, we consider current-induced switchi…
Local Temperatures and Heat Flow in Quantum Driven Systems
Alvaro Caso, Liliana Arrachea, Gustavo S. Lozano
We discuss the concept of local temperature for quantum systems driven out of equilibrium by ac pumps showing explicitly that it is the correct indicator for heat flow. We also sho…
Relation Between Local Temperature Gradients and the Direction of Heat Flow in Quantum Driven Systems
Alvaro Caso, Liliana Arrachea, Gustavo S. Lozano
We introduce thermometers to define the local temperature of an electronic system driven out-of-equilibrium by local ac fields. We discuss the behavior of the local temperature alo…
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…
