New algorithm to measure entanglement entropy

A research team from the Department of Physics, the University of Hong Kong (HKU) has developed a new algorithm to measure entanglement entropy, advancing the exploration of more comprehensive laws in quantum mechanics, a ...

Towards quantum simulation of false vacuum decay

Phase transitions are everywhere, ranging from water boiling to snowflakes melting, and from magnetic transitions in solids to cosmological phase transitions in the early universe. Particularly intriguing are quantum phase ...

New quantum material discovered

In everyday life, phase transitions usually have to do with temperature changes—for example, when an ice cube gets warmer and melts. But there are also different kinds of phase transitions, depending on other parameters ...
