Tensor-network method to simulate strongly interacting quantum thermal machines
Marlon Brenes, Juan José Mendoza-Arenas, Archak Purkayastha +3
We present a methodology to simulate the quantum thermodynamics of thermal machines which are built from an interacting working medium in contact with fermionic reservoirs at fixed…
Speed-ups to isothermality: Enhanced quantum thermal machines through control of the system-bath coupling
Nicola Pancotti, Matteo Scandi, Mark T. Mitchison +1
Isothermal transformations are minimally dissipative but slow processes, as the system needs to remain close to thermal equilibrium along the protocol. Here, we show that smoothly…
Quasiperiodic quantum heat engines with a mobility edge
Cecilia Chiaracane, Mark T. Mitchison, Archak Purkayastha +2
Steady-state thermoelectric machines convert heat into work by driving a thermally-generated charge current against a voltage gradient. In this work, we propose a new class of stea…
Tunable phonon induced steady state coherence in a double quantum dot
Archak Purkayastha, Giacomo Guarnieri, Mark T. Mitchison +2
Charge qubits can be created and manipulated in solid-state double-quantum-dot (DQD) platforms. Typically, these systems are strongly affected by quantum noise stemming from coupli…
Quantum thermal absorption machines: refrigerators, engines and clocks
Mark T. Mitchison
The inexorable miniaturisation of technologies, the relentless drive to improve efficiency and the enticing prospect of boosting performance through quantum effects are all compell…
