Theoretical physicists in the US have discovered a "speed limit" on the time taken for quantum information to spread through ...

Entropy, the amount of molecular disorder, is produced in several systems but cannot be measured directly. A new equation sheds new light on how entropy is produced on a very short time scale in laser ...

Nature is not homogenous. Most of the universe is complex and composed of various subsystems—self-contained systems within a larger whole. Microscopic cells and their surroundings, for example, can be ...

It is one of the most important laws of nature that we know: The famous second law of thermodynamics says that the world gets more and more disordered when random chance is at play. Or, to put it more ...

Three recent studies offer deeper understanding of thermodynamic behaviors with potential to impact materials engineering and energy systems. One shows how increasing elemental diversity in layered ...

What is the concept of entropy? Embedded-system applications that exploit entropy. How to implement entropy. What sources of entropy are available? Computers are designed to be predictable. Under the ...
