All-optical analogue of anti-skyrmions and anti-merons in difference-frequency-generation process
Arannya Ghosh, Mukesh K Shukla, Ritwick Das
In the paraxial domain, a difference-frequency generation (DFG) process provides a versatile platform for exploring non-Hermitian dynamics in an all-classical interaction. This let…

Topological Hall effect in nonlinear optics
Soumik Nandi, Arannya Ghosh, Ashok K Mohapatra +1
We present an experimental evidence of \emph{topological} Hall-effect in an all-optical third-order nonlinear optical process via spatial symmetry-breaking in pseudo-spin textures…
