Energy dynamics, heat production and heat–work conversion with qubits: toward the development of quantum machines

L Arrachea - Reports on Progress in Physics, 2023 - iopscience.iop.org
We present an overview of recent advances in the study of energy dynamics and
mechanisms for energy conversion in qubit systems with special focus on realizations in …

Thermodynamic unification of optimal transport: Thermodynamic uncertainty relation, minimum dissipation, and thermodynamic speed limits

T Van Vu, K Saito - Physical Review X, 2023 - APS
Thermodynamics serves as a universal means for studying physical systems from an energy
perspective. In recent years, with the establishment of the field of stochastic and quantum …

Collective advantages in finite-time thermodynamics

A Rolandi, P Abiuso, M Perarnau-Llobet - Physical Review Letters, 2023 - APS
A central task in finite-time thermodynamics is to minimize the excess or dissipated work W
diss when manipulating the state of a system immersed in a thermal bath. We consider this …

Geometrical bounds of the irreversibility in Markovian systems

T Van Vu, Y Hasegawa - Physical Review Letters, 2021 - APS
We derive geometrical bounds on the irreversibility in both quantum and classical Markovian
open systems that satisfy the detailed balance condition. Using information geometry, we …

Non-abelian eigenstate thermalization hypothesis

C Murthy, A Babakhani, F Iniguez, M Srednicki… - Physical Review Letters, 2023 - APS
The eigenstate thermalization hypothesis (ETH) explains why nonintegrable quantum many-
body systems thermalize internally if the Hamiltonian lacks symmetries. If the Hamiltonian …

Thermodynamic geometry of microscopic heat engines

K Brandner, K Saito - Physical review letters, 2020 - APS
We develop a general framework to describe the thermodynamics of microscopic heat
engines driven by arbitrary periodic temperature variations and modulations of a mechanical …

Optimal cycles for low-dissipation heat engines

P Abiuso, M Perarnau-Llobet - Physical review letters, 2020 - APS
We consider the optimization of a finite-time Carnot engine characterized by small
dissipations. We bound the power with a simple inequality and show that the optimal …

Non-Abelian symmetry can increase entanglement entropy

S Majidy, A Lasek, DA Huse, N Yunger Halpern - Physical Review B, 2023 - APS
The pillars of quantum theory include entanglement and operators' failure to commute. The
Page curve quantifies the bipartite entanglement of a many-body system in a random pure …

Violating the thermodynamic uncertainty relation in the three-level maser

AAS Kalaee, A Wacker, PP Potts - Physical Review E, 2021 - APS
Nanoscale heat engines are subject to large fluctuations which affect their precision. The
thermodynamic uncertainty relation (TUR) provides a trade-off between output power …

Universal bound on energy cost of bit reset in finite time

YZ Zhen, D Egloff, K Modi, O Dahlsten - Physical Review Letters, 2021 - APS
We consider how the energy cost of bit reset scales with the time duration of the protocol. Bit
reset necessarily takes place in finite time, where there is an extra penalty on top of the …
