DESCRIPTION:Prof. Dominik Juraschek\, TU Eindhoven  \nChiral phononics i
 s an emerging field that\, analogously to spintronics and orbitronics\, ut
 ilizes the angular momentum of circularly polarized lattice vibrations to 
 manipulate the properties of quantum materials. This has lead to intriguin
 g discoveries of novel physical phenomena\, including the generation of at
 omistic tesla-scale magnetic fields that promise unprecedented control of 
 magnetic order. In this talk\, I will provide an introduction to the field
  and then present our latest predictions of physical mechanisms arising fr
 om phonon chirality and angular momentum. In particular\, I will demonstra
 te a phonon polariton Hall effect\, in which optical phonons exhibit a tra
 nsverse current in an applied magnetic field\, and a phonon “spin” Hal
 l effect\, in which a transverse phonon angular momentum current is genera
 ted.
