Physics of Phonons in Systems with Approximate Screw Symmetry
Hisayoshi Komiyama, Tiantian Zhang, Shuichi Murakami
Properties of systems with exact n-fold screw symmetry (n=2, 3, 4, 6) have been well studied because they can be understood in terms of space groups. On the other hand, existence o…

Universal features of canonical phonon angular momentum without time-reversal symmetry
Hisayoshi Komiyama, Shuichi Murakami
It is known that phonons have angular momentum, and when the time-reversal symmetry (TRS) is broken, the total phonon angular momentum in the whole system becomes nonzero. In this…
