Disentangling spin polarization from driven circular ionic motion in EuTiO
Clifford J. Allington, Matthew J. Lutz, Enoch +31
Coherently driven circular ionic motion has been reported to produce large helicity-dependent optical responses attributed to transient magnetization. However, the microscopic natu…

Measuring momentum-resolved dissipation of phonon-polaritons in LiNbO with terahertz driving
Megan F. Biggs, Rossella Acampora, Niccolò Sellati +5
Mapping the dispersion of polaritons, hybrid quasiparticles arising from light-matter coupling, can provide key insights into the material dielectric response, coupling strength, a…
