Schwinger-Boson mean-field study of spin-1/2 -- model in honeycomb lattice: thermal Hall signature
Rohit Mukherjee, Ritajit Kundu, Avinash Singh +1
We theoretically investigate, within the Schwinger-Boson mean-field theory, the transition from a gapped quantum spin-liquid, in a - Heisenberg spin-1/2 system in…

Plasmon in Nonsymmorphic Dirac semimetals
Debasmita Giri, Arijit Kundu
We study the collective charge-density modes (plasmons) of two-dimensional nonsymmorphic Dirac semimetals, within the random-phase approximation (RPA) in presence of Coulomb intera…
