Researchers design holographic lenses based on plasma

Holograms are three-dimensional (3D) images produced by interfering beams of light that reflect physical objects or photographs. In recent years, they were introduced in a variety of settings, for instance to enhance employee ...

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 ...

Understanding phase change materials for thermal energy storage

As the world searches for practical ways to decarbonize our activities and mitigate associated climate change, approaches to alternative energy are hampered by the intermittent nature of energy sources, such as solar and ...
