Quantum dynamics and transport in a double well system
Itamar Sela, Doron Cohen
The simplest one-dimensional model for the studying of non-trivial geometrical effects is a ring shaped device which is formed by joining two arms. We explore the possibility to mo…
Quantum Stirring in low dimensional devices
Itamar Sela, Doron Cohen
A circulating current can be induced in the Fermi sea by displacing a scatterer, or more generally by integrating a quantum pump into a closed circuit. The induced current may have…
Renormalization of the dephasing by zero point fluctuations
Swarnali Bandopadhyay, Doron Cohen
We study the role of zero-point-fluctuations (ZPF) in dephasing at low temperature. Unlike the Caldeira-Leggett model where the interaction is with an homogeneous fluctuating field…
Dephasing of a particle in a dissipative environment
Doron Cohen, Baruch Horovitz
The motion of a particle in a ring of length L is influenced by a dirty metal environment whose fluctuations are characterized by a short correlation distance . We analy…
Control of atomic currents using a quantum stirring device
Moritz Hiller, Tsampikos Kottos, Doron Cohen
We propose a BEC stirring device which can be regarded as the incorporation of a quantum pump into a closed circuit: it produces a DC circulating current in response to a cyclic ad…
Restricted quantum-classical correspondence and counting statistics for a coherent transition
Maya Chuchem, Doron Cohen
The conventional probabilistic point of view implies that if a particle has a probability to make a transition from one site to another site, then the average transport should…
