Resolving the nonequilibrium Kondo singlet in energy- and position-space using quantum measurements
André Erpenbeck, Guy Cohen
The Kondo effect, a hallmark of strong correlation physics, is characterized by the formation of an extended cloud of singlet states around magnetic impurities at low temperatures.…
Revealing strong correlations in higher order transport statistics: a noncrossing approximation approach
André Erpenbeck, Emanuel Gull, Guy Cohen
We present a method for calculating the full counting statistics of a nonequilibrium quantum system based on the propagator noncrossing approximation (NCA). This numerically inexpe…
Green's function methods for single molecule junctions
Guy Cohen, Michael Galperin
We present a brief pedagogical review of theoretical Green's function methods applicable to open quantum systems out of equilibrium in general, and single molecule junctions in par…
Numerically exact counting statistics of energy current in the Kondo regime
Michael Ridley, Michael Galperin, Emanuel Gull +1
We use the inchworm Quantum Monte Carlo method to investigate the full counting statistics of particle and energy currents in a strongly correlated quantum dot. Our method is used…
Auxiliary master equation for nonequilibrium dual-fermion approach
Feng Chen, Guy Cohen, Michael Galperin
We introduce auxiliary quantum master equation - dual fermion approach (QME-DF) and argue that it presents a convenient way to describe steady-states of correlated impurity systems…
Numerically exact full counting statistics of the nonequilibrium Anderson impurity model
Michael Ridley, Viveka Nand Singh, Emanuel Gull +1
The time dependent full counting statistics of charge transport through an interacting quantum junction is evaluated from its generating function, controllably computed with the in…
Complete All-Optical Quantum Control of Electron Spins in InAs/GaAs Quantum Dot Molecule
Guy Z. Cohen
The spin states of electrons and holes confined in InAs quantum dot molecules have recently come to fore as a promising system for the storage or manipulation of quantum informatio…
Decoherence and lead induced inter-dot coupling in nonequilibrium electron transport through interacting quantum dots: A hierarchical quantum master equation approach
R. Härtle, G. Cohen, D. R. Reichman +1
The interplay between interference effects and electron-electron interactions in electron transport through an interacting double quantum dot system is investigated using a hierarc…
Generalized projected dynamics for non-system observables of non-equilibrium quantum impurity models
Guy Cohen, Eli Y. Wilner, Eran Rabani
The reduced dynamics formalism has recently emerged as a powerful tool to study the dynamics of non-equilibrium quantum impurity models in strongly correlated regimes. Examples inc…
Reading, writing and squeezing the entangled states of two nanomechanical resonators coupled to a SQUID
Guy Z. Cohen, Massimiliano Di Ventra
We study a system of two nanomechanical resonators embedded in a dc SQUID. We show that the inductively-coupled resonators can be treated as two entangled quantum memory elements w…
Second and higher harmonics generation with memristive systems
Guy Z. Cohen, Yuriy V. Pershin, Massimiliano Di Ventra
We show that memristive systems can be used very efficiently to generate passively both double and higher frequency harmonics. A technique for maximizing the power conversion effic…
Lagrange formalism of memory circuit elements: classical and quantum formulations
G. Z. Cohen, Y. V. Pershin, M. Di Ventra
The general Lagrange-Euler formalism for the three memory circuit elements, namely, memristive, memcapacitive, and meminductive systems, is introduced. In addition, {\it mutual mem…
Cotunneling mechanism of single-electron shuttling
Guy Z. Cohen, V. Fleurov, K. Kikoin
The problem of electron transport by means of a dumbbell shaped shuttle in strong Coulomb blockade regime is solved. The electrons may be shuttled only in the cotunneling regime du…
Application of a semiclassical model for the second-quantized many-electron Hamiltonian to nonequilibrium quantum transport: The resonant level model
David W. H. Swenson, Tal Levy, Guy Cohen +2
A semiclassical (SC) approach is developed for nonequilibrium quantum transport in molecular junctions. Following the early work of Miller and White [J. Chem. Phys. 84, 5059 (1986)…
Filtering and analyzing mobile qubit information via Rashba-Dresselhaus-Aharonov-Bohm interferometers
Amnon Aharony, Yasuhiro Tokura, Guy Z. Cohen +2
Spin-1/2 electrons are scattered through one or two diamond-like loops, made of quantum dots connected by one-dimensional wires, and subject to both an Aharonov-Bohm flux and (Rash…
Time-dependent single electron tunneling through a shuttling nano-island

Guy Cohen, Eran Rabani
An examination of the properties of many-electron conduction through spin-degenerate systems can lead to situations where increasing the bias voltage applied to the system is predi…
