Can quantum systems become more disordered, as thermodynamics would predict? Yes, they can - if a proper definition of "entropy" is used. It is one of the most important laws of nature that we know: ...

Inside high-energy proton collisions, quarks and gluons briefly form a dense, boiling state before cooling into ordinary ...

For decades, physicists have struggled to reconcile the laws governing the very small with those that describe the vast cosmos. Quantum mechanics rules subatomic particles, while general relativity ...

Forgetting feels like a failure of attention, but physics treats it as a fundamental process with a measurable price. At the ...

When the constant-depth circuit is removed, the value of topological entanglement entropy (γ) computed from the state returns to the ideal value (γ₀). Credit: Dr. Bowen Shi. In a new study, scientists ...

By Partha Sinha Entropy fascinates because it announces itself. It spreads, decays and disperses. It makes noise. Like Kali, ...
