Soft-mode nonlinearities away from ferroelectric phase transition
Payel Shee, Ipek Efe, Jingwen Li +3
The paper investigates how electronic polarizability and local-field effects influence the soft optical phonon mode in paraelectric SrTiO₃, using linear and two‑dimensional teraher…

Phonon-polariton mediated dual electromagnetically induced transparency-like response in a THz metamaterial
Amit Haldar, Kshitij V Goyal, Ruturaj V Puranik +9
Light and matter can intertwine to create entirely new quantum states in the so-called strong-coupling regime, allowing unprecedented control over electromagnetic waves. In this wo…
