Soft-mode nonlinearities away from ferroelectric phase transition
Payel Shee, Ipek Efe, Jingwen Li +3
The interplay between ionic and electronic subsystems dictates the behavior of structural phase transitions in polar dielectrics, a coupling mediated by soft optical phonon modes.…

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…

Terahertz crystal electric field transitions in a Kondo-lattice antiferromagnet
Payel Shee, Chia-Jung Yang, Shishir Kumar Pandey +5
Hybridization between the localized f-electrons and the delocalized conduction electrons together with the crystal electric field (CEF) play a determinant role in governing the man…
