OAM-mode sorting with a wavefront twister
Suman Karan, Swati Chaudhary, Harshwardhan Wanare +1
We propose an OAM sorter based on a novel optical element that we refer to as a wavefront twister. It is a generalization of the conventional wavefront rotators such as the Dove pr…
Direct Determination of Photonic Stopband Topological Character: A Framework based on Dispersion Measurements
Nitish Kumar Gupta, Sapireddy Srinivasu, Mukesh Kumar +4
Ascertainment of photonic stopband absolute topological character requires information regarding the Bloch eigenfunction spatial distribution. Consequently, the experimental invest…
Loschmidt echo and Momentum Distribution in a Kitaev Spin Chain
Vimalesh Kumar Vimal, H. Wanare, V. Subrahmanyam
We investigate the Loschmidt echo in a one-dimensional spin chain having Kitaev-type interaction in constant and kicked magnetic fields. The Loschmidt echo for the initial states h…
Controlling propagation of spatial coherence for enhanced imaging through scattering media
Abhinandan Bhattacharjee, Shaurya Aarav, Harshawardhan Wanare +1
It is known that a spatially partially coherent light field produces better imaging contrast compared to a spatially coherent field and that the contrast increases as the spatial c…
Angular Lens
Rishabh Sahu, Swati Chaudhary, Kedar Khare +3
We propose a single phase-only optical element that transforms different orbital angular momentum (OAM) modes into localized spots at separated angular positions on a transverse pl…
Dynamical control of atoms with polarized bichromatic weak field
A. Kani, Harshawardhan Wanare
We propose ultranarrow dynamical control of population oscillation (PO) between ground states through the polarization content of an input bichromatic field. Appropriate engineerin…
