Anomalous” heat flow, which at first appears to violate the second law of thermodynamics, gives physicists a way to detect quantum entanglement without destroying it.

Machine learning models are designed to take in data, to find patterns or relationships within those data, and to use what ...

The intermediate states in photo-excited phase transitions are expected to be inhomogeneous. In this work, a spatially resolved ultrafast X-ray imaging technique shows that the early part of the metal ...
