The microscopic origin of line tension, used in the equilibrium description of liquid drops on flat surfaces, is not well understood. Simulations of water nanodroplets show that structural transitions ...

July 3, 2026 Researchers have created quantum control techniques that can make a system appear to run backward in time. By precisely managing quantum measurements, they can reshape the system's arrow ...

Condensed-matter physics is the study of substances in their solid state. This includes the investigation of both crystalline solids in which the atoms are positioned on a repeating three-dimensional ...
