Quantum transport in Cooper pair splitters using hierarchical equations of motion
Riya Baruah, Neill Lambert, Franco Nori +1
We investigate charge transport in Cooper pair splitters beyond the weak-coupling and Markovian limits. To this end, we employ hierarchical equations of motion (HEOM), which can ca…
Heat, work, and fluctuations in a driven quantum resonator
Riya Baruah, Pedro Portugal, Jun-Zhe Chen +2
A central building block of a heat engine is the working fluid, which mediates the conversion of heat into work. In nanoscale heat engines, the working fluid can be a quantum syste…
Generation of heat pulses in mesoscopic conductors using light fields
Pedro Portugal, Riku Tuovinen, Christian Flindt
We propose to generate heat pulses in mesoscopic conductors using light fields. In contrast to single-electron excitations such as levitons, which are created by accurate voltage d…
Current cross-correlation spectroscopy of Majorana bound states
Michael Ridley, Eliahu Cohen, Christian Flindt +1
The clock speed of topological quantum computers based on Majorana zero mode (MZM)-supporting nanoscale devices is limited by the time taken for electrons to traverse the device. W…
Full counting statistics and first-passage times in quantum Markovian processes: Ensemble relations, metastability, and fluctuation theorems
Paul Menczel, Christian Flindt, Fredrik Brange +2
We develop a comprehensive framework for characterizing fluctuations in quantum transport and nonequilibrium thermodynamics using two complementary approaches: full counting statis…
Floquet-Nambu theory of electron quantum optics with superconductors
Pablo Burset, Benjamin Roussel, Michael Moskalets +1
We present a comprehensive Floquet-Nambu theory to describe the time-dependent quantum transport in mesoscopic circuits involving superconductors. The central object of our framewo…
