Physicists have uncovered a hidden third form of magnetism that challenges more than 100 years of established physics. Called altermagnetism, the discovery could transform future computing and electronics while opening an entirely new frontier in quantum research.

    I went to the Wikipedia entry for altermagnetism and read the first paragraph. I didn’t make it very far before I was reading it in Hubert Farnsworth’s voice.

    In condensed matter physics, altermagnetism is a type of persistent magnetic state in ideal crystals.[1][2][3][4][5] Altermagnetic structures are collinear and crystal-symmetry compensated, resulting in zero net magnetisation.[1][5][6][7] Unlike in an PT-symmetric collinear antiferromagnet, the electronic bands in PT-non-symmetric antiferromagnets (altermagnets) are not Kramers degenerate, but instead depend on the wavevector in a spin-dependent way due to the intrinsic crystal symmetry connecting different magnetic sublattices.[8][9][1][10] Related to this feature, key experimental observations were published in 2024.[11] It has been speculated that altermagnetism may have applications in the field of spintronics

      Ok so when the metaphorical Kramers burst through the door and slams down a few bills on the counter proclaiming they “lost” implies not fornication bets, but healing crystal energy that reacts to the (jokes aside) wavevector in a spin-dependent way; i.e will interact magnetically different depending on the other field’s net spin? I’m picturing a gate that will supress one field but not the other, relative to their spin? Because then it’s huge news I guess but could we really call that a “phase”?
