Phonon angular momentum transfer torque
Verena Brehm, Daniel A. Bustamante Lopez, Shu Zhang +1
Angular momentum in solids is carried by (quasi)particles such as magnons, plasmons, and phonons, and coupling between these reservoirs enables diverse hybrid phenomena. Here, we i…
Precessional modes of phonon angular momentum
Daniel A. Bustamante Lopez, Dominik M. Juraschek
Magnons are collective precessional excitations of electron spins and are ubiquitous in emerging information technologies. Here, we show that the crystal lattice can support an ana…
Ferron Hall effect: Transverse accumulation of polarization driven by thermal gradients in ferroelectrics
Daniel A. Bustamante Lopez, Verena Brehm, Dominik M. Juraschek
The phonon Hall effect describes the generation of a transverse heat current in response to a longitudinal thermal gradient in a magnetic field. Here, we theoretically demonstrate…
Quantifying chirality of phonons
Yu-Chi Huang, Gakuto Kusuno, Yusuke Hashimoto +3
Recent years have witnessed growing interest in chiral phonons, lattice vibrations carrying angular momentum and exhibiting handedness, as revealed by helicity-dependent optical ph…
Atomistic theory of the phonon angular momentum Hall effect
Daniel A. Bustamante Lopez, Verena Brehm, Dominik M. Juraschek
The spin and orbital Hall effects convert longitudinal charge currents into transverse flows of electronic angular momentum. Here we develop an atomistic theory of the recently pro…
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…
Ultrafast simultaneous manipulation of multiple ferroic orders through nonlinear phonon excitation
Daniel A. Bustamante Lopez, Dominik M. Juraschek, Michael Fechner +3
Recent experimental studies have demonstrated the possibility of utilizing strong terahertz pulses to manipulate individual ferroic orders on pico- and femtosecond timescales. Here…
