Phonon Angular Momentum Induced by the Temperature Gradient. [PDF]
Physical Review Letters, 2018 Phonon modes in crystals can have angular momenta in general. It nevertheless cancels in equilibrium when the time-reversal symmetry is preserved. In this Letter, we show that when a temperature gradient is applied and heat current flows in the crystal ...
