Electric field switching of chiral phonons

Michael Grimes, Clifford J. Allington, Hiroki Ueda +8

Lattice vibrations carrying angular momentum, known as chiral phonons, have emerged as a promising route to control and understand complex material properties, yet their determinis…

Lattice excitations with finite polarization and magnetization

Mike Pols, Carl P. Romao, Dominik M. Juraschek

Ferrons are a type of quasiparticle corresponding to elementary excitations of the ferroelectric order. Analogously to how magnons modulate and transport magnetization, ferrons mod…

Anomalous thermal expansion and chiral phonons in BiB $_{3}$ O $_{6}$

Carl P. Romao

The origins of anomalous thermal expansion in the chiral monoclinic solid $α$ -BiB $_{3}$ O $_{6}$ have been studied through ab initio calculations. Positive and negative axial thermal…
