A novel universal light-based technique to control valley polarization in bulk materials
by Phys.org
Phys.org— Electrons inside solid materials can only take certain values of energy. The allowed energy ranges are called "bands," and the space between them, the forbidden energies, is known as "band gaps." Both of them together constitute the "band structure" of the material, which is a unique characteristic of each specific material.
Phys.org—Study shows ultra-thin two-dimensional materials can rotate the polarization of visible light. It has been known for centuries that light exhibits wave-like behavior in certain situations. Some materials are able to rotate the polarization, i.e. the direction of oscillation, of the light wave when the light passes through the material. This property is utilized in a central component of optical communication networks known as an "optical isolator" or "optical diode." This component allows light to propagate in one direction but blocks all light in the other direction.

WV MetroNews—How colleges and universities let protests get out of control. Colleges and universities are traditional centers of intellectual rigor, fountains of diverse opinions and laboratories for ideas. They should be safe spaces for open minds and healthy debate. But as we have seen in recent weeks, the aspirational mission is clouded by blatant anti-Semitism, violence and cowering college administrations. All public universities are subject to
