Entropy is surely one of the most intriguing and misunderstood concepts in all of physics. The entropy of the universe must always increase – so says the second law of thermodynamics. It’s a ...

We establish an upper bound for the entropy, based on the eigenvalue interlacing property, and we incorporate this bound in a branch-and-bound algorithm for the exact solution of the problem. We ...

There is a ruthless and unstoppable law that governs the entire universe, one that no one can escape. This law, known as entropy, is the fundamental force that dictates the slow decay of ...

This innovative approach uses quantum relative entropy, a concept from quantum information theory, to describe the interplay between spacetime geometry and matter.

Time governs every aspect of our universe, yet what would happen if it suddenly ceased to exist? In this video we explore the ...

With fast heating, sheets of gold can shoot past the theoretical maximum temperature a solid can have before it melts – raising questions about what the true limits are ...
