(PhysOrg.com) -- We like to think that we’ve got hydrogen, one of the most basic of elements, figured out. However, hydrogen can still surprise, especially once scientists start probing its properties on the most fundamental ...
So far, physicists have primarily studied topological phases in conservatively coupled systems. These are systems with dynamics that do not dissipate and a phase space that does not shrink over time. They are in stark contrast ...
Just as an electrical switch regulates the flow of electric current, thermal switches can control the flow of heat. These switches serve as thermal control devices and are useful for thermal management applications. For example, ...

(Phys.org) —Piezoelectric materials, which produce electricity in response to mechanical stress, account for a $12 billion global industry that is projected to grow at a rate of 13.2% per year, according to a recent report ...
Rice University engineers who mimic atom-scale processes to make them big enough to see have modeled how shear influences grain boundaries in polycrystalline materials.
