complexes have revealed quantum coherences with timescales comparable to those of …

One-shot operational quantum resource theory

ZW Liu, K Bu, R Takagi - Physical review letters, 2019 - APS
A fundamental approach for the characterization and quantification of all kinds of resources
is to study the conversion between different resource objects under certain constraints. Here …

Quasiprobability distribution for heat fluctuations in the quantum regime

A Levy, M Lostaglio - PRX Quantum, 2020 - APS
The standard approach to deriving fluctuation theorems fails to capture the effect of quantum
correlation and coherence in the initial state of the system. Here, we overcome this difficulty …

Correlations in quantum thermodynamics: Heat, work, and entropy production

S Alipour, F Benatti, F Bakhshinezhad, M Afsary… - Scientific reports, 2016 - nature.com
We provide a characterization of energy in the form of exchanged heat and work between
two interacting constituents of a closed, bipartite, correlated quantum system. By defining a …

Redox conditions correlated with vibronic coupling modulate quantum beats in photosynthetic pigment–protein complexes

JS Higgins, MA Allodi, LT Lloyd… - Proceedings of the …, 2021 - National Acad Sciences
Quantum coherences, observed as time-dependent beats in ultrafast spectroscopic
experiments, arise when light–matter interactions prepare systems in superpositions of …

Correlation-enabled energy exchange in quantum systems without external driving

T Pyhäranta, S Alipour, AT Rezakhani, T Ala-Nissila - Physical Review A, 2022 - APS
We study the role of correlation in mechanisms of energy exchange between an interacting
bipartite quantum system and its environment by decomposing the energy of the system to …

Redox conditions affect ultrafast exciton transport in photosynthetic pigment–protein complexes

MA Allodi, JP Otto, SH Sohail, RG Saer… - The Journal of …, 2018 - ACS Publications
Pigment–protein complexes in photosynthetic antennae can suffer oxidative damage from
reactive oxygen species generated during solar light harvesting. How the redox environment …

Unreliability of mutual information as a measure for variations in total correlations

S Alipour, S Tuohino, AT Rezakhani, T Ala-Nissila - Physical Review A, 2020 - APS

and quantum systems, such as information and energy exchanges. The quantum mutual …

Wormholes and the thermodynamic arrow of time

ZY Xian, L Zhao - Physical Review Research, 2020 - APS
In classical thermodynamics, heat cannot spontaneously pass from a colder system to a
hotter system, which is called the thermodynamic arrow of time. However, if the initial states …

Decoupling of information propagation from energy propagation

RH Jonsson - 2016 - uwspace.uwaterloo.ca
Information and energy are concepts central to our understanding of nature. Their relevance,
in physics, ranges from fundamental physics, eg, in black hole physics, all the way to future …
