Hyperaccurate thermoelectric currents
André, M. Timpanaro, Giacomo Guarnieri +1
Thermodynamic currents can fluctuate significantly at the nanoscale. But some currents fluctuate less than others. Hyperaccurate currents are those which fluctuate the least, in th…
Periodically refreshed baths to simulate open quantum many-body dynamics
Archak Purkayastha, Giacomo Guarnieri, Steve Campbell +2
Obtaining dynamics of an interacting quantum many-body system connected to multiple baths initially at different, finite, temperatures and chemical potentials is a challenging prob…
Action quantum speed limits
Eoin O'Connor, Giacomo Guarnieri, Steve Campbell
We introduce action quantum speed limits (QSLs) as a family of bounds on the minimal time to connect two states that, unlike the usual geometric approach, crucially depend on how t…
Thermodynamics of precision in quantum nano-machines
Antoine Rignon-Bret, Giacomo Guarnieri, John Goold +1
Fluctuations strongly affect the dynamics and functionality of nanoscale thermal machines. Recent developments in stochastic thermodynamics have shown that fluctuations in many far…
Quantum fluctuations hinder finite-time information erasure near the Landauer limit
Harry J. D. Miller, Giacomo Guarnieri, Mark T. Mitchison +1
Information is physical but information is also processed in finite time. Where computing protocols are concerned, finite-time processing in the quantum regime can dynamically gene…
Quantum Coherence and Ergotropy
Gianluca Francica, Felix C. Binder, Giacomo Guarnieri +3
Constraints on work extraction are fundamental to our operational understanding of the thermodynamics of both classical and quantum systems. In the quantum setting, finite-time con…
