Impact of gapped spin-orbit excitons on low energy pseudospin exchange interactions
Sreekar Voleti, F David Wandler, Arun Paramekanti
The quest for exotic quantum magnetic ground states, including the Kitaev spin liquid and quantum spin-ices, has led to the discovery of several quantum materials where low energy…
Proximate Dirac spin liquid in honeycomb lattice - XXZ model: Numerical study and application to cobaltates
Anjishnu Bose, Manodip Routh, Sreekar Voleti +4
Recent theoretical and experimental work suggest that the honeycomb cobaltates, initially proposed as candidate Kitaev quantum magnets, are in fact described by a pseudospin-…
Probing octupolar hidden order via Janus impurities
Sreekar Voleti, Koushik Pradhan, Subhro Bhattacharjee +2
Quantum materials with non-Kramers doublets are a fascinating venue to realize multipolar hidden orders. Impurity probes which break point group symmetries, such as implanted muons…
Octupolar order and Ising quantum criticality tuned by strain and dimensionality: Application to -orbital Mott insulators
Sreekar Voleti, Arijit Haldar, Arun Paramekanti
Recent experiments have discovered multipolar orders in a variety of -orbital Mott insulators. Motivated by uncovering the exchange interactions which underlie octupolar order p…
XY magnetism, Kitaev exchange, and long-range frustration in the honeycomb cobaltates
Shreya Das, Sreekar Voleti, Tanusri Saha-Dasgupta +1
The quest for Kitaev quantum spin liquids has led to great interest in honeycomb quantum magnets with strong spin-orbit coupling. It has been recently proposed that even Mott insul…
Multipolar magnetism in d-orbital systems: Crystal field levels, octupolar order, and orbital loop currents
Sreekar Voleti, Dalini D. Maharaj, Bruce D. Gaulin +2
Quantum magnets with spin , which arise in spin-orbit coupled Mott insulators, can potentially display multipolar orders. We carry out an exact diagonalization study of a simp…
