In everyday life, all matter exists as either a gas, liquid, or solid. In quantum mechanics, however, it is possible for two distinct states to exist simultaneously. An ultracold quantum system, for ...

In recent months, I’ve mentioned super-solids a couple of times, which is a bit unusual for something we haven’t been sure actually exists. However, a recent paper seems to offer some quite strong ...

Boron-based solid propellants have attracted considerable attention due to boron’s exceptional volumetric and gravimetric calorific values, which are critical for high-energy propulsion systems.
