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.

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...

It’s always good when your hard work reflects well on you. With the discovery of the giant polarization rotation of light, that is literally so.

Nanotechnology Now Our NanoNews Digest Sponsors Home > Press > Thin is now in to turn terahertz polarization: Rice lab’s discovery of ‘magic angle’ builds on its ultrathin, highly aligned nanotube films Rice University physicists have made unique broadband polarization rotators with ultrathin carbon nanotube films. The films optically rotate polarized light output by 90 degrees, but only when the input light’s polarization is at a specific angle with respect to the nanotube alignment direction: the “magic angle.” (Credit: Kono Laboratory/Rice University) Abstract: It’s always good when...
