Photon-assisted stochastic resonance in nanojunctions
Michael Ridley, Leo Bellassai, Michael Moskalets +2
We study stochastic resonance in molecular junctions driven by a periodically-varying external field. This is done using the time-dependent Landauer-B{ü}ttiker formalism, which fol…
A many-body approach to transport in quantum systems: From the transient regime to the stationary state
M. Ridley, N. W. Talarico, D. Karlsson +2
We review one of the most versatile theoretical approaches to the study of time-dependent correlated quantum transport in nano-systems: the non-equilibrium Green's function (NEGF)…
Quantum interference and the time-dependent radiation of nanojunctions
Michael Ridley, Lev Kantorovich, Robert van Leeuwen +1
Using the recently developed time-dependent Landauer-Büttiker formalism and Jefimenko's retarded solutions to the Maxwell equations, we show how to compute the time-dependent elect…
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…
Electron traversal times in disordered graphene nanoribbons
Michael Ridley, Michael A. Sentef, Riku Tuovinen
Using the partition-free time-dependent Landauer-B{ü}ttiker formalism for transient current correlations, we study the traversal times taken for electrons to cross graphene nanorib…
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…
Formal equivalence between partitioned and partition-free quenches in quantum transport
Michael Ridley, Riku Tuovinen
In this paper we review the partitioned and partition-free approaches to the calculation of the time-dependent response of a molecular junction to the switch-on of an arbitrary tim…
Time-dependent Landauer-Büttiker approach to charge pumping in AC-driven graphene nanoribbons
Michael Ridley, Riku Tuovinen
We apply the recently-developed partition-free time-dependent Landauer-Büttiker (TD-LB) formalism to the study of periodically-driven transport in graphene nanoribbons (GNR). When…
Partition-free theory of time-dependent current correlations in nanojunctions in response to an arbitrary time-dependent bias
Michael Ridley, Angus MacKinnon, Lev Kantorovich
Working within the Nonequilibrium Green's Function (NEGF) formalism, a formula for the two-time current correlation function is derived for the case of transport through a nanojunc…
Calculation of the current response in a nanojunction for an arbitrary time-dependent bias: application to the molecular wire
Michael Ridley, Angus MacKinnon, Lev Kantorovich
Recently [Phys. Rev. B 91, 125433 (2015)] we derived a general formula for the time-dependent quantum electron current through a molecular junction subject to an arbitrary time-dep…
Current through a multi-lead junction caused by applied bias with arbitrary time-dependence
Michael Ridley, Angus MacKinnon, Lev Kantorovich
We apply the Nonequilibrium Green's Function (NEGF) formalism to the problem of a multi-terminal nanojunction subject to an arbitrary time-dependent bias. In particular, we show th…
