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…

Dynamic control of ferroic domain patterns by thermal quenching
Jan Gerrit Horstmann, Ehsan Hassanpour, Yannik Zemp +3
Controlling the domain structure of ferroic materials is key to manipulating their functionality. Typically, quasi-static electric, magnetic, or strain fields are exploited to tran…

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…
