Coexistence of static order and spin dynamics in an S = 5/2 frustrated triangular antiferromagnet
U. Jena, B. Sana, Satish Kumar +6
Frustrated triangular-lattice antiferromagnets in the classical high-spin limit provide a paradigmatic setting in which the interplay of competing exchange interactions, anisotropy…
Signature of spin liquid state in a frustrated 3D antiferromagnet
Satish Kumar, U. Jena, A. Bandhopadhay +4
Frustrated pyrochlore lattices in transition-metal oxides provide an ideal platform for realizing exotic quantum states, including spin liquids with unconventional low-energy excit…
Topological spin freezing in frustrated quantum materials
U. Jena, M. Barman, A. Pradhan +1
Competing interactions, non-trivial electronic band topology, quantum fluctuations, and the interplay between emergent degrees of freedom in frustrated quantum materials can give r…
Melting upon cooling in a quantum magnet
K. JaksetiÄ, T. Arh, M. Pregelj +19
Heating enhances thermal fluctuations and typically leads to melting of solids, but in exceptional cases, heating can also cause liquids to solidify. The paradigm of this counterin…
Magnetic properties of a buckled honeycomb lattice antiferromagnet
A. Yadav, U. Jena, A. Pradhan +2
The intriguing interplay between competing degrees of freedom in frustrated magnets can lead to non-trivial magnetic phenomena with exotic low-energy excitations that are highly re…
Emergent dimensional reduction in a distorted kagome magnet driven by exchange hierarchy
Umashankar Jena, Satish Kumar, Harald O. Jeschke +2
Frustrated kagome magnets provide a fertile platform for unconventional collective quantum phenomena, yet the role of lattice distortion in reorganizing magnetic degrees of freedom…
