The light interacts with the cavity and makes an arbitrary number of bounces before leaking out. This emergent light is traditionally treated as heat in quantum simulations. However, it can still be ...

SIAM Journal on Applied Mathematics, Vol. 67, No. 1 (2006), pp. 46-68 (23 pages) New quantum hydrodynamic equations are derived from a Wigner-Boltzmann model, using the quantum entropy minimization ...

A new study from Oxford shows quantum clocks may not be as energy efficient as once thought, but only when we look at them.

Entropy also increases in initially ordered quantum systems until it reaches a final state of disorder. Entropy and the direction of time Equating 'entropy' with 'disorder' is not entirely correct.

Today’s most advanced clocks keep time with an incredibly precise rhythm. But a new experiment suggests that clocks’ precision comes at a price: entropy. Entropy, or disorder, is created each time a ...

The most accepted version of the third law of thermodynamics, the unattainability principle, states that any process cannot reach absolute zero temperature in a finite number of steps and within a ...

Journal for General Philosophy of Science / Zeitschrift für allgemeine Wissenschaftstheorie, Vol. 37, No. 2 (Oct., 2006), pp. 287-306 (20 pages) Well known quantum and time paradoxes, and the ...

The second law of thermodynamics is one of those puzzling laws of nature that simply emerges from the fundamental rules. It says that entropy, a measure of disorder in the Universe, must always ...

Recently, when we were talking about why time only moves forward, we got into talking about the Second Law of Thermodynamics. It says that disorder, otherwise known as entropy, must always increase.
