Observation of cooperative strong coupling between optical phonon and crystal-field excitations in a pseudo Jahn-Teller system
Fangliang Wu, Xiaoxuan Ma, Zhongwei Zhang +6
Cooperative interactions between localized electronic excitations and crystal lattice are central to the emergence of complex structural phases in materials. However, the scaling r…

Altermagnetic magnon transport in the \textit{d}-wave altermagnet \ch{LuFeO3}
Edgar Galindez-Ruales, Wanting Yang, Tobias Dannegger +11
Altermagnets exhibit a spin-split band structure despite having zero net magnetization, leading to special magnonic properties such as anisotropic magnon lifetimes and field-free s…
