Anisotropic exciton polariton pairs as a platform for PT-symmetric non-Hermitian physics
Devarshi Chakrabarty, Avijit Dhara, Pritam Das +3
Non-Hermitian systems with parity-time (PT) symmetry have been realized using optical constructs in the classical domain, leading to a plethora of non-intuitive phenomena. However,…
Zero-Threshold PT-Symmetric Polariton-Raman Laser
Avijit Dhara, Pritam Das, Devarshi Chakrabarty +3
Anisotropy endows topological aspects in optical systems and furnishes a platform to explore non-Hermitian physics, which can be harnessed for the polarization-selective amplificat…
Observable in Dirac Scotogenic Model
Debasish Borah, Pritam Das, Dibyendu Nanda
We study the possibility of probing the radiative Dirac seesaw model with dark sector particles going inside the loop, popularly referred to as the Dirac scotogenic model via measu…
Spin-Polarisation measurement using NbN-Insulator-Ferromagnet Tunnel Junction with oxidized barrier
Pritam Das, John Jesudasan, Rudheer Bapat +1
We report a two-step process for the fabrication of superconductor-insulator-normal metal tunnel junctions using NbN as the superconducting electrode and its surface oxide as the i…
Origin of neutrino masses, dark matter, leptogenesis, and inflation in a seesaw model with triplets
Pritam Das, Najimuddin Khan
We consider a new physics model, where the Standard Model (SM) is extended by hyperchargeless triplet fermions and Higgs triplet with hypercharge . The first two generat…
A steady state approach for studying valley relaxation using optical vortex beam
Aswini Kumar Pattanayak, Pritam Das, Avijit Dhara +5
Spin-valley coupling in monolayer transition metal dichalcogenides gives rise to valley polarization and coherence effect, limited by intervalley scattering caused by exciton-phono…
