Radiation families emitted by a discrete soliton in parity-time-symmetric waveguide arrays
Anuj P. Lara, Ambaresh Sahoo, Samudra Roy
We investigate the dynamics of a spatial discrete soliton and the radiation families emitted by it inside a parity-time ()-symmetric waveguide array with alternate ga…
Plasmon-enhanced circular dichroism spectroscopy of chiral drug solutions
Matteo Venturi, Raju Adhikary, Ambaresh Sahoo +9
We investigate the potential of surface plasmon polaritons at noble metal interfaces for surface-enhanced chiroptical sensing of dilute chiral drug solutions. The high quality fact…
Theoretical investigations on Kerr and Faraday rotations in topological multi-Weyl Semimetals
Supriyo Ghosh, Ambaresh Sahoo, Snehasish Nandy
Motivated by the recent proposal of giant Kerr rotation in WSMs, we investigate the Kerr and Faraday rotations in time-reversal broken multi-Weyl semimetals (mWSMs) in the absence…
Variational approach to study solitary waves in -symmetric nonlinear couplers
Ambaresh Sahoo, Amarendra K. Sarma
We theoretically investigate the solitary waves and their switching dynamics in a -symmetric directional fiber coupler, exhibiting Kerr nonlinearity, by developing a…
Two-way enhancement of sensitivity by tailoring higher-order exceptional points
Ambaresh Sahoo, Amarendra K. Sarma
Higher-order exceptional points in non-Hermitian systems have recently been used as a tool to engineer high-sensitivity devices, attracting tremendous attention from multidisciplin…
Effects of ultrafast free-carrier dynamics on frequency comb generation in graphene-based microresonators
Ambaresh Sahoo
Manipulation of the dynamics of cavity solitons, precise control of frequency comb spectra and nonlinear response of microresonators through exploitation of the ultrafast optical p…
