The phase and the group velocity of light propagating in conventional optical media cannot exceed the speed of light in ...

Emission is then obtained at the difference frequency of the ... regarding generation of terahertz radiation changed in the 1980s when lasers producing femtosecond pulses became available.

Scientists successfully induced a new magnetic state in an antiferromagnet using only light, which could have big implications for data storage technologies.

Chirality is a fundamental property of matter that determines many biological, chemical and physical phenomena. Chiral solids, for example, offer exciting opportunities for catalysis, sensing and ...

Humans typically blink 4 times per second, equivalent to a frequency of 4 Hz. Blinking at a rate of 1 billion times per second, or 1 GHz, is not possible for a human being. But this is the current ...

Using a terahertz laser, scientists successfully vibrated atoms at the same frequency as the material ... in the form of a near-infrared terahertz pulse directed through an organic crystal ...

By applying intense pulses of terahertz-frequency light to this material, they were able to control this transition, placing the material in a metastable magnetic state that lasts for more than 2.5 ...

Scientists from the (MPSD) and MIT have achieved a groundbreaking feat — creating a stable, long-lasting magnetic state in an antiferromagnetic material using only light. This discovery could lead to ...

Instead of a stone, the scientists used laser pulses, focusing them on a sharp ... including its speed, damping, and frequency, without requiring complex computational transformations.
