Frustrated magnetic order in hybrid Kitaev spin-orbital models
Ivan Dutta, Aayush Vijayvargia, Anamitra Mukherjee +2
Spin-orbital generalization of Kitaev model provides a robust extension to the original Kitaev model. However, real materials often exhibit competing interactions that break exact…
Enhanced Andreev Reflection in Flat-Band Systems: Wave Packet Dynamics, DC Transport and the Josephson Effect
Sarbajit Mazumdar, Anamitra Mukherjee, Kush Saha +1
We investigate Andreev reflection (AR) in a proximity-induced normal-superconductor (NS) junction within the extended lattice, emphasizing the impact of flat band…
Exactly solvable spin liquids in Kitaev bilayers and moiré superlattices
Ivan Dutta, Anamitra Mukherjee, Onur Erten +1
Building on the recent advancements on moiré superlattices, we propose an exactly solvable model with Kitaev-type interactions on a bilayer honeycomb lattice for both AA stacking a…
Spin-imbalance induced buried topological edge currents in Mott \& topological insulator heterostructures
Rahul Ghosh, Subhajyoti Pal, Kush Saha +1
We theoretically investigate the heterostructure between a ferrimagnetic Mott insulator and a time-reversal invariant topological band insulator on the two-dimensional Lieb lattice…
Disorder-induced delocalization and reentrance in a Chern-Hopf insulator
Soumya Bera, Ivan Dutta, Roderich Moessner +1
The Chern-Hopf insulator is an unconventional three-dimensional topological insulator with a bulk gap and gapless boundary states without protection from global discrete symmetries…
