Entropy-Driven Altermagnetism from Thermal Magnons
Tanaya Halder, Ashis K. Nandy, Anamitra Mukherjee
We identify a route to altermagnetism driven by entropy upon heating and demonstrate it in a minimal square-lattice antiferromagnet. An exchange modulation is entropically favored…
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…
The interplay of magnetic order with the electronic scattering and crystal-field effects in a metallic ferromagnet
Payel Shee, Tanaya Halder, Chia-Jung Yang +9
The interplay between magnetic order, charge dynamics, and crystal field excitations underpins the emergent ground states of rare-earth intermetallics. Using time-domain terahertz…
Mott Criticality as the Confinement Transition of a Pseudogap-Mott Metal
Abhirup Mukherjee, S. R. Hassan, Anamitra Mukherjee +3
The phenomenon of Mott insulation involves the localization of itinerant electrons due to strong local repulsion. Upon doping, a pseudogap (PG) phase emerges - marked by selective…
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…
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…
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…
