Nonlinearity Selective Quasi Bound States in the Continuum via Symmetry Protected Decoupling in χ(2) Thin Films
Ardra Muriyankandathil, Parikshit Sahatiya, Brian Abbey +1
Second-harmonic generation in resonant structures is commonly evaluated in terms of intracavity field enhancement at the fundamental and harmonic frequencies. Here, we formulate no…
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…
Impact of FBG feedback phase on laser dynamics
Martin Skënderas, Spencer W. Jolly, Nitish Gupta +2
Fiber Bragg Gratings have been advantageously used to improve the chaotic properties of semiconductor lasers. Though these components are known to be highly sensitive to environmen…
Non-Hermitian Topoelectrical Circuits: Expedient Tools for Topological State Engineering with Gain-Loss Modulation
Nitish Kumar Gupta, Arun M. Jayannavar
The congregation of topological quantum and classical systems with the ideas of non-Hermitian physics has generated enormous research interest in the last few years. While the conc…
Topological Photonic Systems: Virtuous Platforms to Study Topological Quantum Matter
Nitish Kumar Gupta, Arun M. Jayannavar
Topological insulators are a new class of materials that have engendered considerable research interest among the condensed matter community owing primarily to their application pr…
Clocking the Quantum Sojourn Time: Spurious Scatterings and Correction to the Larmor Clock
Nitish Kumar Gupta, A. M. Jayannavar, S. Anantha Ramakrishna
We revisit the notions of the quantum-mechanical sojourn time in the context of the quantum clocks to enquire whether the sojourn time be clocked without the clock affecting the dy…
Emergence in Science
Nitish Kumar Gupta, A. M. Jayannavar
In the scientific literature, the term emergent phenomena is invoked in the context of a collective behavior observed in a complex adaptive system that exhibits no correspondence w…
