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…
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…
Missing spectral weight in a heavy-fermion system far above Néel temperature
Jingwen Li, Debankit Priyadarshi, Chia-Jung Yang +6
The competition between the Kondo spin-screening effect and the Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction in heavy-fermion systems drives the quantum phase transition betwee…
