Correlation-Induced Topological Reconstruction in a Periodically Driven Kagome Mott Insulator
Rahul Ghosh, Subhajyoti Pal, Ganesh C Paul
We study the interplay between electronic correlations and circularly polarized periodic driving in the Hubbard model on a Kagome lattice. Using Brillouin-Wigner perturbation theor…
Emergent Quasiparticles \& Field-Tuned RIXS Spectra in a Trimerized Spin-1/2 Chain
Subhajyoti Pal, Pradeep Thakur, Ashis Kumar Nandy +1
We investigate spin-flip excitations in the spin-1/2 trimer chain , featuring an antiferromagnetic exchange motif -- with . Using d…
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…
Predicting Fractionalized Multi-Spin Excitations in Resonant Inelastic X-ray Spectra of Frustrated Spin-1/2 Trimer Chains
Prabhakar, Subhajyoti Pal, Umesh Kumar +2
We theoretically investigate the resonant inelastic X-ray scattering (RIXS) spectra in a quasi-1D chain of weakly coupled frustrated spin-1/2 trimers, as realized in NaCu$_{3…
