| 英文摘要 | Chirality is an indispensable conceptthat pervades fundamentalscience and nature, manifesting itself in diverse forms, e.g., quasiparticles, and crystal structures. Ofparticular interest are Weyl phonons carrying specific Chern numbersand chiral phonons doing circular motions. Up to now, they have beenstudied independently and the interpretations of chirality seem tobe different in these two concepts, impeding our understanding. Here,we demonstrate that they are entangled in chiral crystals. Employinga typical chiral crystal of elementary tellurium (Te) as a case study,we expound on the intrinsic relationship between Chern number of Weylphonons and pseudoangular momentum (PAM, l ( ph )) of chiral phonons. We propose Raman scatteringas a new technique to demonstrate the existence of Weyl phonons inTe, by detecting the chirality-induced energy splitting between thetwo constituent chiral phonon branches for Weyl phonons. Moreover,we also observe the obstructed phonon surface states for the firsttime. |
