Copper-oxide (CuO2) superconductors, such as Bi2Sr2CaCu2O8+δ (Bi2212), have unusually high critical temperatures. Optical ...

In a given domain the molecules in adjacent planes show a slight angle of twist relative to one another, characteristic of cholesteric liquid crystal ... planes as shown by birefringence studies.

The optical Kerr effect is a well-known phenomenon in which an electric field creates birefringence in a material. Researchers have now demonstrated this effect using single-cycle terahertz pulses ...

Certain types of Fine Ceramic crystals contain semiconductive, ferroelectric, and ferromagnetic properties. These demonstrate fluorescence, phosphorescence, color tone, and birefringence ...
