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…
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…
Ruddlesden-Popper and perovskite phases as a material platform for altermagnetism
F. Bernardini, M. Fiebig, A. Cano
The subclass of collinear antiferromagnets where spin Kramers degeneracy is broken -- resulting in ferromagnetic-like properties -- offers exciting new opportunities in magnetism a…
Magnetoelectric phase control at domain-wall-like epitaxial oxide multilayers
Elzbieta Gradauskaite, Chia-Jung Yang, Shovon Pal +2
Ferroelectric domain walls are nanoscale objects that can be created, positioned, and erased on demand. They often embody functional properties that are distinct from the surroundi…
