Dynamical multiferroicity in framework materials
Marek Matas, Carl P. Romao
Dynamical multiferroicity, which describes the magnetic fields generated by circularly polarized phonons in materials, is an established mechanism for optical control of magnetism.…
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…
Structural Evolution during Reversible Halogen Intercalation into WTe2: Commensurate-Incommensurate WTe2I and Multistage WTe2Brx (x = 0.5, 1.0 and 1.25)
Patrick Schmidt, Carl P. Romao, Hans-Jürgen Meyer
Halogen intercalation into the layered material tungsten ditelluride (WTe2) provides a unique pathway to tune its structural and electronic properties. In this study, we detail the…
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 BiBO
Carl P. Romao
The origins of anomalous thermal expansion in the chiral monoclinic solid -BiBO have been studied through ab initio calculations. Positive and negative axial thermal…
Origins of anisotropic thermal expansion in flexible materials
Carl P. Romao
A definition of the Grüneisen parameters for anisotropic materials is derived based on the response of phonon frequencies to uniaxial stress perturbations. This Grüneisen model rel…
