2D material controls light twice stronger

Scientists have taken a step closer to the goal of controlling light by identifying nonlinear optical phenomena occurring in heterobilayers composed of two-dimensional materials.

Ultra-thin designer materials unlock quantum phenomena

A team of theoretical and experimental physicists have designed a new ultra-thin material that they have used to create elusive quantum states. Called one-dimensional Majorana zero energy modes, these quantum states could have a huge impact for quantum computing.

Ultracold atoms reveal a new type of quantum magnetic behavior

A new study illuminates surprising choreography among spinning atoms: Researchers reveal how magnetic forces at the quantum, atomic scale affect how atoms orient their spins.

Catalyst research: Molecular probes require highly precise calculations

Scientists have demonstrated the use of calculation methods with so-called hybrid functionals for the reliable interpretation of experimental data.

Polariton interactions: Light matters

Why do two-dimensional exciton-polaritons interact? The answer is found to lie in the 'light-like' characteristics of these quasiparticles. This is important for future applications using polaritons in atomically-thin semiconductors, such as ultra-low energy electronics.

Organic molecules on a metal surface... a machinist's best friend

How can you improve the cutting of 'gummy' metals? Engineers have come up with an answer - and their findings may help in manufacturing products and reducing component failures.
