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 ...

Superelasticity of a photoactuating chiral crystal

Superelasticity is an elastic response to an applied external force that occurs via phase transformation. The resulting actuation of the materials is an elastic response to external stimuli, including light and heat. While ...

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 ...

Triple phase transition in a photonic quasicrystal observed

Together with their colleague Professor Stefano Longhi (Polytechnic Institute of Milan), physicists from the group of Professor Alexander Szameit (University of Rostock) have discovered a triple phase transition. At the critical ...
