Quantum work and the thermodynamic cost of quantum measurements
(American Physical Society, 2016-07)
Quantum work is usually determined from two projective measurements of the energy at the beginning and at the end of a thermodynamic process. However, this paradigm cannot be considered thermodynamically consistent as it ...
Thermal baths as quantum resources: More friends than foes?
(IOP Publishing, 2015-11-06)
In this article we argue that thermal reservoirs (baths) are potentially useful resources in processes involving atoms interacting with quantized electromagnetic fields and their applications to quantum technologies. One ...
Dynamics and Thermodynamics of Linear Quantum Open Systems
(Amer Physical Soc, 2013-04-29)
We analyze the evolution of the quantum state of networks of quantum oscillators coupled with arbitrary external environments. We show that the reduced density matrix of the network always obeys a local master equation ...
Fundamental limits for cooling of linear quantum refrigerators
(American Physical Society, 2017-01)
We study the asymptotic dynamics of arbitrary linear quantum open systems that are periodically driven while coupled with generic bosonic reservoirs. We obtain exact results for the heat flowing from each reservoir, and ...
Using a quantum work meter to test non-equilibrium fluctuation theorems
(Nature, 2017-12)
Work is an essential concept in classical thermodynamics, and in the quantum regime, where the notion of a trajectory is not available, its definition is not trivial. For driven (but otherwise isolated) quantum systems, ...
Periodic Energy Transport and Entropy Production in Quantum Electronics
(Molecular Diversity Preservation International, 2016-11)
The problem of time-dependent particle transport in quantum conductors is nowadays a well established topic. In contrast, the way in which energy and heat flow in mesoscopic systems subjected to dynamical drivings is a ...
Measuring work and heat in ultracold quantum gases
(IOP Publishing, 2015-03)
We propose a feasible experimental scheme to direct measure heat and work in cold atomic setups. The method is based on a recent proposal which shows that work is a positive operator valued measure (POVM). In the present ...
Magnetic Otto engine for an electron in a quantum dot: Classical and quantum approach
(MDPI AG, 2019)
We studied the performance of classical and quantum magnetic Otto cycle with a working substance composed of a single quantum dot using the Fock-Darwin model with the inclusion of the Zeeman interaction. Modulating an ...
Magnetic engine for the single particle landau problem
(MDPI AG, 2017)
We study the effect of the degeneracy factor in the energy levels of the well-known Landau
problem for a magnetic engine. The scheme of the cycle is composed of two adiabatic processes and
two isomagnetic processes, ...
Magnetic engine for the single-particle Landau problem
(MDPI AG, 2017)
We study the effect of the degeneracy factor in the energy levels of the well-known Landau problem for a magnetic engine. The scheme of the cycle is composed of two adiabatic processes and two isomagnetic processes, driven ...
