First passage times for continuous quantum measurement currents

MJ Kewming, A Kiely, S Campbell, GT Landi - Physical Review A, 2024 - APS
The first passage time (FPT) is the time taken for a stochastic process to reach a desired
threshold. In this Letter we address the FPT of the stochastic measurement current in the …

Numerically exact full counting statistics of the energy current in the Kondo regime

M Ridley, M Galperin, E Gull, G Cohen - Physical Review B, 2019 - APS
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 to …

First-passage times in renewal and nonrenewal systems

K Ptaszyński - Physical Review E, 2018 - APS
Fluctuations in stochastic systems are usually characterized by full counting statistics, which
analyzes the distribution of the number of events taking place in the fixed time interval. In an …

Counting quantum jumps: A summary and comparison of fixed-time and fluctuating-time statistics in electron transport

SL Rudge, DS Kosov - The Journal of Chemical Physics, 2019 - pubs.aip.org
In quantum transport through nanoscale devices, fluctuations arise from various sources: the
discreteness of charge carriers, the statistical nonequilibrium that is required for device …

Electronic statistics on demand: Bunching, antibunching, positive, and negative correlations in a molecular spin valve

NS Davis, SL Rudge, DS Kosov - Physical Review B, 2021 - APS
One of the long-standing goals of quantum transport is to use the noise, rather than the
average current, for information processing. However, achieving this requires on-demand …

Revealing strong correlations in higher-order transport statistics: A noncrossing approximation approach

A Erpenbeck, E Gull, G Cohen - Physical Review B, 2021 - APS
We present a method for calculating the full counting statistics of a nonequilibrium quantum
system based on the propagator noncrossing approximation (NCA). This numerically …

Waiting time distribution and current correlations via a Majorana single-charge transistor

W Fu, SS Ke, Y Guo, HW Zhang, HF Lü - Physical Review B, 2022 - APS
We investigate the electron transport and the waiting time distribution (WTD) in a topological
superconducting Coulomb island system weakly coupled to two metallic leads. A pair of …

Current cross-correlations and waiting time distributions in Andreev transport through Cooper pair splitters based on a triple quantum dot system

K Wrześniewski, I Weymann - Physical Review B, 2020 - APS
We study the spin-resolved subgap transport in a triple quantum-dot system coupled to one
superconducting and two ferromagnetic leads. We examine the Andreev processes in the …

Waiting time statistics in boundary-driven free fermion chains

GT Landi - Physical Review B, 2021 - APS
We study the waiting time distributions of quantum chains coupled to two Lindblad baths at
each end. Our focus is on free fermion chains, where we derive closed-form expressions in …

Synchronized coherent charge oscillations in coupled double quantum dots

E Kleinherbers, P Stegmann, J König - Physical Review B, 2021 - APS
We study coherent charge oscillations in double quantum dots tunnel coupled to metallic
leads. If two such systems are coupled by Coulomb interaction, there are, in total, six …
