Phonon rotoelectric effect
Masato Hamada, Shuichi Murakami
In crystals with time-reversal symmetry but without inversion symmetry, the phonon angular momentum can be generated by the temperature gradient, and it is called phonon thermal Ed…
Conversion between electron spin and microscopic atomic rotation
Masato Hamada, Shuichi Murakami
We theoretically investigate the microscopic mechanism of conversion between the electron spin and the microscopic local rotation of atoms in crystals. In phonon modes with angular…
Phonon Angular Momentum Induced by Temperature Gradient
Masato Hamada, Emi Minamitani, Motoaki Hirayama +1
Phonon modes in crystals can have angular momenta in general. It nevertheless cancels in equilibrium when the time-reversal symmetry is preserved. In this paper we show that when a…
Spin current generation and magnetic response in carbon nanotubes by the twisting phonon mode
Masato Hamada, Takehito Yokoyama, Shuichi Murakami
We theoretically investigate spin current and magnetic response induced by the twisting phonon mode in carbon nanotubes via the spin-rotation coupling. An effective magnetic field…
