Temperature dependence of Coulomb drag between finite-length quantum wires
J. Peguiron, C. Bruder, B. Trauzettel
We evaluate the Coulomb drag current in two finite-length Tomonaga-Luttinger-liquid wires coupled by an electrostatic backscattering interaction. The drag current in one wire shows…
Dynamics of Quantum Dissipative Systems: The Example of Quantum Brownian Motors
J. Peguiron
Brownian motors, i.e. devices able to produce useful work out of thermal forces with the help of other unbiased forces, provide an ideal benchmark for the investigation of quantum…
Spin-transfer torque in magnetic multilayer nanopillars
J. Peguiron, M. -S. Choi, C. Bruder
We consider a quasi one-dimensional configuration consisting of two small pieces of ferromagnetic material separated by a metallic one and contacted by two metallic leads. A spin-p…
Quantum Brownian motion in ratchet potentials: duality relation and its consequences
J. Peguiron, M. Grifoni
Quantum Brownian motion in ratchet potentials is investigated by means of an approach based on a duality relation. This relation links the long-time dynamics in a tilted ratchet po…
Duality Relation for Quantum Ratchets
J. Peguiron, M. Grifoni
A duality relation between the long-time dynamics of a quantum Brownian particle in a tilted ratchet potential and a driven dissipative tight-binding model is reported. It relates…
Quantum ratchet effect for vortices
J. B. Majer, J. Peguiron, M. Grifoni +2
We have measured a quantum ratchet effect for vortices moving in a quasi-one-dimensional Josephson junction array. In this solid-state device the shape of the vortex potential ener…
