Machine-learning models of matter beyond interatomic potentials

Combining electronic structure calculations and machine learning (ML) techniques has become a common approach in the atomistic modeling of matter. Using the two techniques together has allowed researchers, for instance, to ...

Research sparks new insights on laser welding

On its surface, the work is deceptively simple: Shoot a high-power laser beam onto a piece of metal for a fraction of a second and see what happens. But researchers say the physics of laser welding is surprisingly complex. ...

Physicists shed X-ray light on melting polymers

Physicists from the Moscow Institute of Physics and Technology (MIPT) and Lomonosov Moscow State University have combined thermal analysis and X-ray scattering—two techniques for studying crystal structure—in one experimental ...

Measuring the heat capacity of condensed light

Liquid water is a very good heat storage medium – anyone with a Thermos bottle knows that. However, as soon as water boils or freezes, its storage capacity drops precipitously. Physicists at the University of Bonn have ...

Hidden order uncovered in spin liquid Gd3Ga5O12

When a material undergoes a phase transition from a disordered to an ordered state, its properties change and these changes are observed via macroscopic observables such as specific heat capacity measurements.
