Electron-Mediated Phonon Polaritons in Quantum Cavities
Mattia Udina, David Hagenmüller, Indranil Paul
Phonon-photon coupling in quantum materials is commonly treated as an effective direct interaction, neglecting the crucial role played by electrons. Here we develop a gauge-invaria…
THz-induced phonomagnetism in diamagnetic quantum paraelectric KTaO
C. Kadlec, F. Kadlec, D. Repček +13
The current efforts striving to develop new ways of data manipulation are aimed at ultrafast control of magnetization in magnetic materials, as well as at inducing magnetic moments…
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…
Anharmonic phonon coupling enabled by local inversion symmetry breaking at domain walls in ferroelastics
Seyyed Jabbar Mousavi, Vivek Unikandanunni, Niccolo Sellati +7
In ferroelastic materials, spontaneous symmetry breaking leads to the formation of twin domains. Although the bulk crystal typically remains centrosymmetric, inversion symmetry can…
Revealing the nature of the charge density wave order of ErTe via Raman scattering under anisotropic strain
Theotime Freitas, Mattia Udina, Alexandr Alekhin +7
The nature of the charge density wave (CDW) order of the rare-earth tritelluride ErTe3 is investigated by Raman scattering under anisotropic strain. The CDW state of ErTe3 is uncon…
