Dephasing in a quantum pump
J. N. H. J. Cremers, P. W. Brouwer
We study how dephasing affects the distribution of the dc current pumped through a chaotic quantum dot. We introduce dephasing by the addition of a voltage probe to the quantum dot…
Spin, spin-orbit, and electron-electron interactions in mesoscopic systems
Yuval Oreg, P. W. Brouwer, X. Waintal +1
We review recent theoretical developments about the role of spins, electron-electron interactions, and spin-orbit coupling in metal nanoparticles and semiconductor quantum dots. Fo…
Density of proper delay times in chaotic and integrable quantum billiards
M. G. A. Crawford, P. W. Brouwer
We calculate the density P(τ) of the eigenvalues of the Wigner-Smith time delay matrix for two-dimensional rectangular and circular billiards with one opening. For long times, the…
Spin torque in a magnetic trilayer coupled to a superconductor
Xavier Waintal, Piet W. Brouwer
A ferromagnet-normal-metal-ferromagnet trilayer does not conserve spin current and as a result, the conduction electrons can create a torque on the magnetic moments. When the trila…
Magnetic exchange interaction induced by a Josephson current
Xavier Waintal, Piet W. Brouwer
We show that a Josephson current flowing through a ferromagnet-normal-metal-ferromagnet trilayer connected to two superconducting electrodes induces an equilibrium exchange interac…
Interaction Induced Restoration of Phase Coherence
A. A. Clerk, P. W. Brouwer, V. Ambegaokar
We study the conductance of a quantum T-junction coupled to two electron reservoirs and a quantum dot. In the absence of electron-electron interactions, the conductance is sens…
