You've all heard about ferromagnetism.

How about antiferromagnetism?

Well, there's a new thing, it's called altermagnetism.

Altermagnetism: A new type of magnetism, with broad implications for technology and research

There is now a new addition to the magnetic family: thanks to experiments at the Swiss Light Source SLS, researchers have proved the existence of altermagnetism. The experimental discovery of this new branch of magnetism is reported in Nature and signifies new fundamental physics, with major...

And, what benefit will this be for mankind?

I'm glad you asked that question


One benefit is, an altermagnetic ANN can solve a 50 city traveling salesman problem in milli-seconds.

One benefit is, an altermagnetic ANN can solve a 50 city traveling salesman problem in milli-seconds.

How? And what problems?

How? And what problems?

How? Stochastic optimization.

This is the traveling salesman problem:

"Collective behavior" is one of the great secrets of the universe.

First we learned about it in simple terms like temperature and Boltzmann's equation.

Now we're learning about it in more sophisticated terms like AI transformers and criticality.

And of course entanglement, which has yet to be understood although we're already using it.

Exploiting disorder to harvest heat energy: The potentialities of 2D magnets for thermoelectric applications

Thermoelectric systems are a green and sustainable way to harvest energy from any form of heat that otherwise would be wasted. At the core of this energy conversion process is the so-called Seebeck effect, which describes the voltage building up on a material exposed to a temperature difference.
