Entanglement dynamics of Multi-Level Atoms embedded in Photonic Crystals: Leveraging Resonant Dipole-Dipole Interactions and Quantum Interference
Nancy Ghangas, Shubhrangshu Dasgupta
We present a comprehensive investigation of entanglement dynamics in multi-level V-type atomic systems embedded within photonic crystals. We mainly focus on the synergistic roles o…

Coherent control of nonreciprocal optical properties of the defect modes in 1D defective photonic crystals with atomic doping
Nancy Ghangas, Shubhrangshu Dasgupta
We investigate the spectral properties of photonic crystals, lacking parity-time (PT) symmetry, using scattering matrix formalism. We show using the symmetry properties of matrices…
