Controlling the thermodynamics of light

Scientists offer a more generalized theoretical description of chemical potential (usually denoted by the Greek letter mu) for light and show how mu can be controlled and applied in a number of physics research areas.

Optoelectronic microprocessors built using existing chip manufacturing

High-performance prototype means chipmakers could now start building optoelectronic chips.

Scientists make advances toward affordable photoelectrochemical (PEC) production of hydrogen

Scientists took a different approach to the PEC process, which uses solar energy to split water into hydrogen and oxygen. The process requires special semiconductors, the PEC materials and catalysts to split the water.

Researchers found an unconventional phase transition in photonic structures

Physicists have researched the phenomenon of phase transition between photonic crystals and metamaterials - two types of periodic structures capable of manipulating light in intricate ways.

A quantum of light for material science

Computer simulations that predict the light-induced change in the physical and chemical properties of complex systems, molecules, nanostructures and solids usually ignore the quantum nature of light. Scientists have now shown how the effects of the photons can be properly included in such calculations.
