Transport in molecular states language: Generalized quantum master equation approach
Massimiliano Esposito, Michael Galperin
A simple scheme capable of treating transport in molecular junctions in the language of many-body states is presented. An ansatz in Liouville space similar to generalized Kadanoff-…
Nonequilibrium fluctuations, fluctuation theorems, and counting statistics in quantum systems
Massimiliano Esposito, Upendra Harbola, Shaul Mukamel
Fluctuation theorems (FTs), which describe some universal properties of nonequilibrium fluctuations, are examined from a quantum perspective and derived by introducing a two-point…
Thermoelectric efficiency at maximum power in a quantum dot
Massimiliano Esposito, Katja Lindenberg, Christian Van den Broeck
We identify the operational conditions for maximum power of a nanothermoelectric engine consisting of a single quantum level embedded between two leads at different temperatures an…
Single-electron counting spectroscopy: simulation study of porphyrin in a molecular junction
Sven Welack, Jeremy B. Maddox, Massimiliano Esposito +2
Electron counting of a single porphyrin molecule between two electrodes shows a crossover from sub- to super-Poissonian statistics as the bias voltage is scanned. This is attribute…
Continuous time random walk for open systems: Fluctuation theorems and counting statistics
Massimiliano Esposito, Katja Lindenberg
We consider continuous time random walks (CTRW) for open systems that exchange energy and matter with multiple reservoirs. Each waiting time distribution (WTD) for times between st…
