Minimal Self-Contained Quantum Refrigeration Machine Based on Four Quantum Dots
Davide Venturelli, Rosario Fazio, Vittorio Giovannetti
We present a theoretical study of an electronic quantum refrigerator based on four quantum dots arranged in a square configuration, in contact with as many thermal reservoirs. We s…
Imaging backscattering through impurity-induced antidots in quantum Hall constrictions
Nicola Paradiso, Stefan Heun, Stefano Roddaro +6
We exploit the biased tip of a scanning gate microscope (SGM) to induce a controlled backscattering between counter-propagating edge channels in a wide constriction in the quantum…
Elastic precession of electronic spin states in interacting integer quantum Hall edge channels
Davide Venturelli, Denis Feinberg
We consider the effect of Coulomb interactions in the propagation of electrons, prepared in arbitrary spin states, on chiral edge channels in the integer quantum Hall regime. Elect…
