Quantum Hall realization of polarized intensity interferometry
Krishanu Roychowdhury, Disha Wadhawan, Poonam Mehta +2
We combine the ideas of intensity interferometry, polarization optics and Bell's measurement into an experimental proposal which is hosted in a = quantum Hall (QH) edge s…
Doping effects on the magnetic frustration in the honeycomb iridates
Sujit Das, Er Jia Guo, Krishanu Roychowdhury
We investigate the doping effects of magnetic and nonmagnetic impurities injected to the honeycomb iridate sample of Na2IrO3 . Both the doping result in changing the ordering tempe…
Z2 topological liquid of hard-core bosons on a kagome lattice at 1/3 filling
Krishanu Roychowdhury, Subhro Bhattacharjee, Frank Pollmann
We consider hard-core bosons on the kagome lattice in the presence of short range repulsive interactions and focus particularly on the filling factor 1/3. In the strongly interacti…
Pseudospin-valve effect on transport in junctions of three-dimensional topological insulator surfaces
Sthitadhi Roy, Krishanu Roychowdhury, Sourin Das
We show that the surface states of pristine 3D topological insulators (TIs) are analogs of ferromagnetic half metals due to complete polarization of an emergent momentum independen…
