Non-positive energy quasidistributions in coherent collision models
Marco Pezzutto, Gabriele De Chiara, Stefano Gherardini
We determine the Kirkwood-Dirac quasiprobability (KDQ) distribution associated to the stochastic instances of internal energy variations for the quantum system and environment part…
Continuous Variable Structured Collision Models
Anton Corr, Stefano Cusumano, Gabriele De Chiara
Quantum collision models allow for the dynamics of open quantum systems to be described by breaking the environment into small segments, typically consisting of non-interacting har…
Quantum machines powered by correlated baths
Gabriele De Chiara, Mauro Antezza
We consider thermal machines powered by locally equilibrium reservoirs that share classical or quantum correlations. The reservoirs are modelled by the so-called collisional model…
Three-qubit refrigerator with two-body interactions
Adam Hewgill, J. Onam González, José J. Palao +3
We propose a three-qubit setup for the implementation of a variety of quantum thermal machines where all heat fluxes and work production can be controlled. An important configurati…
Energetic cost of quantum control protocols
Obinna Abah, Ricardo Puebla, Anthony Kiely +3
We quantitatively assess the energetic cost of several well-known control protocols that achieve a finite time adiabatic dynamics, namely counterdiabatic and local counterdiabatic…
The Rhombi-Chain Bose-Hubbard Model: geometric frustration and interactions
Christine Cartwright, Gabriele De Chiara, Matteo Rizzi
We explore the effects of geometric frustration within a one-dimensional Bose-Hubbard model using a chain of rhombi subject to a magnetic flux. The competition of tunnelling, self-…
