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.…

Kohn anomaly in a topological phase transition
Jingwen Li, Arpita Dutta, Kush Saha +4
Topological crystalline insulators extend the concept of topological insulators by hosting surface states protected by crystallographic symmetry. Their topological phase transition…

Discovery of a non-Hermitian phase transition in a bulk condensed-matter system
Jingwen Li, Michael Turaev, Masakazu Matsubara +5
Phase transitions are fundamental in nature. A small parameter change near a critical point leads to a qualitative change in system properties. Across a regular phase transition, t…
