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…
Joint statistics of work and entropy production along quantum trajectories
Harry J. D. Miller, M. Hamed Mohammady, Martí Perarnau-Llobet +1
In thermodynamics, entropy production and work quantify irreversibility and the consumption of useful energy, respectively, when a system is driven out of equilibrium. For quantum…
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…
Work extraction from coherently activated maps via quantum switch
Kyrylo Simonov, Gianluca Francica, Giacomo Guarnieri +1
We characterize the impact that the application of two maps in a quantum-controlled order has on the process of work extraction via unitary cycles and its optimization. The control…
Quantum many-body attractors
Berislav Buca, Archak Purkayastha, Giacomo Guarnieri +3
Complex dynamics when occurring autonomously, i.e. without external driving, is usually associated with everyday length scales and classical physics, e.g. living organisms. This dy…
Enhanced steady-state coherence via repeated system-bath interactions
Ricardo Román-Ancheyta, Michal Kolář, Giacomo Guarnieri +1
The appearance of steady-state coherence (SSC) from system-bath interaction proves that quantum effects can appear without an external drive. Such SSC could become a resource to de…
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 work statistics with initial coherence
María García Díaz, Giacomo Guarnieri, Mauro Paternostro
The Two Point Measurement scheme for computing the thermodynamic work performed on a system requires it to be initially in equilibrium. The Margenau-Hill scheme, among others, exte…
Thermodynamic uncertainty relation in slowly driven quantum heat engines
Harry J. D. Miller, M. Hamed Mohammady, Martí Perarnau-Llobet +1
Thermodynamic Uncertainty Relations express a trade-off between precision, defined as the noise-to-signal ratio of a generic current, and the amount of associated entropy productio…
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…
In situ thermometry of a cold Fermi gas via dephasing impurities
Mark T. Mitchison, Thomàs Fogarty, Giacomo Guarnieri +3
The precise measurement of low temperatures is a challenging, important and fundamental task for quantum science. In particular, in-situ thermometry is highly desirable for cold at…
Non-equilibrium steady-states of memoryless quantum collision models
Giacomo Guarnieri, Daniele Morrone, Barış Çakmak +2
We investigate the steady state properties arising from the open system dynamics described by a memoryless (Markovian) quantum collision model, corresponding to a master equation i…
