Engines are systems and devices that convert one form of energy into another, typically into
a more useful form that can perform work. In the classical setup, physical, chemical, and …

There are several mathematical formulations of quantum mechanics. The Schrödinger
picture expresses quantum states in terms of wavefunctions over, eg position or momentum …

In this tutorial, we present the definition, interpretation, and properties of some of the main
quasiprobabilities that can describe the statistics of measurement outcomes evaluated at …

Operator noncommutation, a hallmark of quantum theory, limits measurement precision,
according to uncertainty principles. Wielded correctly, though, noncommutation can boost …

Although classical thermal machines power industries and modern living, quantum thermal
engines have yet to prove their utility. Here, we demonstrate a useful quantum absorption …

Abstract The Kirkwood-Dirac quasiprobability distribution, intimately connected with the
quantum correlation function of two observables measured at distinct times, is becoming …

Recent work has revealed the central role played by the Kirkwood-Dirac quasiprobability
(KDQ) as a tool to properly account for non-classical features in the context of condensed …

Kirkwood-Dirac representations of quantum states are increasingly finding use in many
areas within quantum theory. Usually, representations of this sort are only applied to provide …

I identify a fundamental difference between classical and quantum dynamics in the linear
response regime by showing that the latter is, in general, contextual. This allows me to …

In quadratic fermionic models, we determine a quantum correction to the work statistics after
both a sudden quench and a time-dependent driving. Such a correction lies in the …
