Dynamic Jahn-Teller effect in the strong spin-orbit coupling regime

Henrik Moodysson Rønnow, Oleg Yazyev, Ivica Zivkovic, Jian Rui Soh, Ravi Yadav, Jana Pásztorová, Davor Tolj

Exotic quantum phases, arising from a complex interplay of charge, spin, lattice and orbital degrees of freedom, are of immense interest to a wide research community. A well-known example of such an entangled behavior is the Jahn-Teller effect, where the l ...
