Symposium Phonon Properties of Materials: Modeling and Experimentation
Presentation Title Phonons and Twisting Symmetries in Non-symmorphic Materials
Author(s) Lucas Lindsay
On-Site Speaker (Planned) Lucas Lindsay
Abstract Scope Here I will discuss the role of structural twisting and symmetry in determining the vibrational behaviors of non-symmorphic materials and how these translate into spectral features and functionalities. We advance a ‘twist’ dynamical description of quasiparticles (e.g., phonons, Bloch electrons) in chiral and achiral crystals. This twisting description provides a fresh perspective on symmetry-enforced crossings, quasiparticle interactions, scattering observables, and band topologies. L.L. acknowledges support from the U.
