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: ...

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 ...

Electron–proton collisions Study reveals importance of entanglement entropy. (Courtesy: Kevin Coughlin/Brookhaven National Laboratory) An international team of physicists has used the principle of ...

Why is there something rather than nothing? Using a Socratic approach, we survey the best scientific ideas in physics ...

The rationality of scientific concept formation in theory transitions, challenged by the thesis of semantic incommensurability, can be restored by the "Chains of Meaning" approach to concept formation ...
