The Interplay of Spin and Charge Channels in Zero Dimensional Systems
M. N. Kiselev, Yuval Gefen
We present a full fledged quantum mechanical treatment of the interplay between the charge and the spin zero-mode interactions in quantum dots. Quantum fluctuations of the spin-mod…
Can Quasi-Particles Tunnel Through A Barrier?
Elad Shopen, Yuval Gefen, Yigal Meir
This is a qualitative description of a systematic analysis carried out by us. We address the question of whether fractionally charged particles, in the context of the fractional qu…
Geometric nature of the environment-induced Berry phase and geometric dephasing
Robert S. Whitney, Yuriy Makhlin, Alexander Shnirman +1
We investigate the geometric phase or Berry phase (BP) acquired by a spin-half which is both subject to a slowly varying magnetic field and weakly-coupled to a dissipative environm…
High cumulants of current fluctuations out of equilibrium
D. B. Gutman, Yuval Gefen, A. D. Mirlin
We consider high order current cumulants in disordered systems out of equilibrium. They are interesting and reveal information which is not easily exposed by the traditional shot n…
Quantum Interferometry with Electrons: Outstanding Challenges
Yuval Gefen
Recent experiments involving semiconducting quantum dots embedded in Aharonov-Bohm interferometry setups suggest that information concerning the phase of electron wavefunctions can…
The Signs of Quantum Dot-Lead Matrix Elements: The Effect on Transport vs. Spectral Properties
Alessandro Silva, Yuval Oreg, Yuval Gefen
A small quantum dot coupled to two external leads is considered. Different signs of the dot-leads coupling matrix elements give rise to qualitatively different behavior of physical…
