Nematic order in topological SYK models
Andrew Hardy, Anjishnu Bose, Arun Paramekanti
We study a class of multi-orbital models based on those proposed by Venderbos, Hu, and Kane which exhibit an interplay of topology, interactions, and fermion incoherence. In the no…
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…
Topological features in the ferromagnetic Weyl semimetal CeAlSi: Role of domain walls
M. M. Piva, J. C. Souza, V. Brousseau-Couture +8
In the ferromagnetic (FM) Weyl semimetal CeAlSi both space-inversion and time-reversal symmetries are broken. Our quantum oscillation (QO) data indicate that the FM ordering modifi…
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…
Chiral Broken Symmetry Descendants of the Kagomé Lattice Chiral Spin Liquid
Anjishnu Bose, Arijit Haldar, Erik S. Sørensen +1
The breaking of chiral and time-reversal symmetries provides a pathway to exotic quantum phenomena and topological phases. In particular, the breaking of chiral (mirror) symmetry i…
