A quantum thermal machine surpassing the classical thermodynamic limit on precision
Simon Sundelin, Ludvig Nordqvist, Khalak Mahadeviya +4
Precision in nonequilibrium processes comes at a thermodynamic cost: suppressing fluctuations generally requires increased dissipation. Thermodynamic uncertainty relations (TURs) m…
Characterizing quantum precision enhancement for multiple currents in open quantum systems
Khalak Mahadeviya, Sheikh Parvez Mandal, Mahasweta Pandit +3
The kinetic uncertainty relation (KUR) constrains fluctuations of individual currents in classical nonequilibrium systems in terms of the dynamical activity, which quantifies the a…
Thermal robustness of sensing quantum phases of matter via qubit probes
Sambunath Das, Hari Kumar Yadalam, Mark T. Mitchison +1
We study the effect of temperature on the ability of a qubit probe to distinguish between different phases in strongly correlated systems. Now to this end, we investigate a spin-1/…
Current fluctuations in a non-additive open quantum system: breakdown of the quantum-jump approach
Ilia Khomchenko, Saulo V. Moreira, Emanuel Schwarzhans +2
Open quantum system dynamics is efficiently described by the quantum master equation formalism. Therein, quantum master equations in Lindblad form constitute an important subclass…
Autonomous oscillations in quantum electromechanics: tensor network treatment
Mahasweta Pandit, Sheikh Parvez Mandal, Mark T. Mitchison +1
Transport-induced self-sustained oscillations in electromechanical systems convert a static electrochemical bias into robust, autonomous oscillatory motion in the absence of any ex…
Optimal current-based sensing of phonon temperature using a finite reservoir
Sindre Brattegard, Stephanie Matern, Mark T. Mitchison +1
In realistic nanoscale transport set-ups, electron-phonon coupling leads to the exchange of heat between phonon baths and electronic reservoirs with finite heat capacities. Such ex…
Process-tensor approach to full counting statistics of charge transport in quantum many-body circuits
Hari Kumar Yadalam, Mark T. Mitchison
We introduce a numerical tensor-network method to compute the statistics of the charge transferred across an interface partitioning an interacting one-dimensional many-body lattice…
