SPICE Workshop on Chiral Phonons, July 29th - 31st 2025
Yoshihiko Togawa
A polarization of angular momenta appears under charge or thermal flow as a manifestation of time-even pseudo scalar, which works as a microscopic chiral term and hybridizes translational and rotational degrees of freedom in driven chiral media. Notably, such a polarized state of electron spins or atomic vibrations (chiral phonons) is detectable electrically. In addition, non-local spin detection is achievable over micrometers and even centimeters. In the talk, I would focus on recent experimental progress on these key findings made with various kinds of chiral inorganic materials.
