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…

The interplay of magnetic order with the electronic scattering and crystal-field effects in a metallic ferromagnet
Payel Shee, Tanaya Halder, Chia-Jung Yang +9
The interplay between magnetic order, charge dynamics, and crystal field excitations underpins the emergent ground states of rare-earth intermetallics. Using time-domain terahertz…
