Though a cornerstone of thermodynamics, entropy remains one of the most vexing concepts to teach budding physicists in the classroom. Physics teachers designed a hand-held model to demonstrate the ...

Entropy production lies at the heart of non-equilibrium thermodynamics, a field that examines systems away from equilibrium where continuous energy flows and irreversible processes dominate. In such ...

Quantum thermodynamics has emerged as an innovative field that integrates the principles of quantum mechanics with classical thermodynamic concepts to describe systems beyond equilibrium. Central to ...

The clock the team used to demonstrate this principle consists of a pair of quantum dots coupled by a thin tunnelling barrier ...

Scientists learned that reading a quantum clock requires orders of magnitude more energy than running it. This surprising imbalance reveals that observation itself shapes the flow and thermodynamics ...

Entropy, introduced by Rudolf Clausius in 1865, is a way to quantify the amount of energy dispersion within a system. It reflects how energy, whether thermal or chemical, becomes more scattered ...

A deep understanding of the irreversibility of the arrow of time cannot ignore the quantum nature of the world that surrounds us. A deep understanding of the irreversibility of the arrow of time ...

A study led by the University of Oxford has identified a surprising source of entropy in quantum timekeeping—the act of ...

WASHINGTON, Sept. 6, 2023 – Though a cornerstone of thermodynamics, entropy remains one of the most vexing concepts to teach budding physicists in the classroom. As a result, many people oversimplify ...
