Although the detailed physics of what goes on inside a laser is typically complex, all conventional lasers share a common basic operational principle: a process known as the stimulated emission of ...

Researchers have experimentally caused electrons to bend in bilayer graphene with the use of light. The way electrons flow in materials determine its electronic properties. For example, when a voltage ...

Superradiance When multiple electrons emit light in a coordinated manner, the resulting emission is much stronger than the sum of individual emissions. (Courtesy ...

I first learned of this area of research as a graduate student in physical chemistry. My doctoral adviser’s group had a project dedicated to studying chemical reactions with attosecond pulses. Before ...

Scientists have observed a quantum fluid of electrons in graphene for the first time, showing near-perfect fluid behaviour and shedding light on a quantum physics puzzle. In a collaborative effort, ...

In a collaborative effort, researchers at the Indian Institute of Science and Japan's National Institute for Materials Science have captured an elusive fluid state in graphene. The study was published ...

In the Van Allen radiation belts, electrons can reach almost the speed of light. Researchers have revealed conditions for such strong accelerations. They had demonstrated in 2020: during solar storm ...

A team of researchers from Boston College has created a new metallic specimen where the motion of electrons flows in the same way water flows in a pipe—fundamentally changing from particle-like to ...
