A new publication from Opto-Electronic Advances; DOI  10.29026/oea.2025.240250, discusses on-chip multi-channel near-far field terahertz vortices with parity breaking and active modulation.

The symmetry of moving around in a circle amounts to the law of conservation of angular momentum. Symmetry in time – that is, physics remaining the same when translated forwards or backwards in ...

Emmy Noether’s groundbreaking theorem transformed physics by linking symmetry to conservation laws. If you were drifting ...

“We saw that some rotational quantum states were somewhat weakly populated by the collisions while other states that were superficially very similar (that is, with the same energy and same angular ...

Everything in this universe is connected. Every human being, every living animal, every tree, rock or even the grass that we ...

Three other states – Louisiana, New Hampshire and Wyoming – have enacted similar laws in recent months. Supporters call the efforts a security measure and say they're trying to reinforce ...

No matter what you do, matter can neither be created nor destroyed. This property of the universe is called the law of ...

I’ve practiced law in Lancaster, a community known for its tradition of family, faith and being a good neighbor. We care ...
