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 ...

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: ...

For more than a century, gravity has been the stubborn outlier in physics, perfectly described on cosmic scales yet refusing to mesh with the quantum rules that govern everything else. A growing camp ...

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 ...

We have been taught to think of entropy as a bad thing. "Things fall apart; the centre cannot hold;/Mere anarchy is loosed upon the world," wrote William Butler Yeats in the aftermath of World War I, ...

In recent years, progress has been made on many of the long-standing questions in high-energy physics and quantum gravity utilizing concepts from information theory. One key object of study has been ...

"Hearst Magazines and Yahoo may earn commission or revenue on some items through the links below." A new paper suggests that time can actually flow forward and backward. Microscopic systems can ...

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 ...
