Ambipolar magneto-optical response of ultra-low carrier density topological insulators
Dipanjan Chaudhuri, Maryam Salehi, Sayak Dasgupta +5
We have investigated the THz range magneto-optical response of ultralow carrier density films of SbTe using time-domain THz polarimetry. Undoped SbTe has a chemical…

Theory of spin waves in a hexagonal antiferromagnet
Sayak Dasgupta, Oleg Tchernyshyov
We construct a field-theoretic description of spin waves in hexagonal antiferromagnets with three magnetic sublattices and coplanar magnetic order. The three Goldstone…
