The Leggett-Garg inequality in electron interferometers
Clive Emary, Neill Lambert, Franco Nori
We consider the violation of the Leggett-Garg inequality in electronic Mach-Zehnder inteferometers. This set-up has two distinct advantages over earlier quantum-transport proposals…
Reverse quantum state engineering using electronic feedback loops
Gerold Kiesslich, Clive Emary, Gernot Schaller +1
We propose an all-electronic technique to manipulate and control interacting quantum systems by unitary single-jump feedback conditioned on the outcome of a capacitively coupled el…
Spin entangled two-particle dark state in quantum transport through coupled quantum dots
Christina Pöltl, Clive Emary, Tobias Brandes
We present a transport setup of coupled quantum dots that enables the creation of spatially separated spin-entangled two-electron dark states. We prove the existence of an entangle…
Transport through single-level systems: Spin dynamics in the nonadiabatic regime
A. Metelmann, T. Brandes
We investigate the Fano-Anderson model coupled to a large ensemble of spins under the influence of an external magnetic field. The interaction between the two spin systems is treat…
Transport and semiclassical dynamics of coupled quantum dots interacting with a local magnetic moment
Klemens Mosshammer, Gerold Kiesslich, Tobias Brandes
We present a theory of magnetotransport through a system of two coupled electronic orbitals, where the electron spin interacts with a (large) local magnetic moment via an exchange…
A diagrammatic description of the equations of motion, current, and noise within the second-order von Neumann approach
O. Karlström, C. Emary, P. Zedler +5
We investigate the second-order von Neumann approach from a diagrammatic point-of-view and demonstrate its equivalence with the resonant tunneling approximation. Investigation of h…
