Gauge-Invariant Phase Mapping to Intensity Lobes of Structured Light via Closed-Loop Atomic Dark States
Nayan Sharma, Ajay Tripathi
We present an analytical model showing how the gauge-invariant loop phase in a three-level closed-loop atomic system imprints as bright-dark lobes in Laguerre Gaussian probe beam i…

Simple Vector Magnetometer Based on Ground State Hanle Effect
Nayan Sharma, Ranjit Kumar Singh, Ajay Tripathi
We present a method for determining the azimuthal phase (angle) of a magnetic field by exploiting phase matching of laser beams in a ground-state Hanle effect (GHSE) configuration.…

Effect of polarisation on two-photon resonance in a large Zeeman manifold
Nayan Sharma, Ranjit Kumar Singh, Souvik Chatterjee +2
In this study, we present numerical investigations on a large Zeeman manifold in an electromagnetically induced transparency (EIT) medium, focusing on the D1 and D2 lines of 87 Rb…
