Phonons are collective atomic vibrations, or quasiparticles, that act as the main heat carriers in a crystal lattice. Under certain circumstances, their properties can be modified by electric fields or light. But until now, nobody noticed they can respond to magnetic fields as well.

E-Mail IMAGE: A Rice University-led study finds a unique form of tunable and ultrastrong spin-spin interactions in orthoferrites under a strong magnetic field. The discovery has implications for quantum simulation and sensing.... view more Credit: Illustration by Motoaki Bamba/Kyoto University HOUSTON - (May 25, 2021) - Sometimes things are a little out of whack, and it turns out to be exactly what you need. That was the case when orthoferrite crystals turned up at a Rice University laboratory slightly misaligned. Those crystals inadvertently became the basis of a discovery that sh...
