Chemical Frequency Combs in Reaction-Diffusion Oscillators
Krishnesh Krishnakumar Nair, Madhurendra Mishra, Zhen Qi +1
Frequency combs, evenly spaced spectral lines locked to one fundamental frequency, are well known in optics and have also been found in phononic, magnonic, ferroelectric, and cosmo…
On the Nonlinear Sensitivity of Phononic Frequency Combs to Physical Perturbations
Madhurendra Mishra, Zhen Qi, Adarsh Ganesan
Phononic frequency combs offer a rich platform for nonlinear sensing, yet how their observable properties respond to changes in physical parameters remains poorly understood. Using…
Financial Frequency Combs
Madhurendra Mishra, Armaan Aryan, Arsh Gogia +1
Frequency combs are discrete, equally spaced, phase-coherent spectral lines that emerge from nonlinear mode coupling in physical systems. We show that the incommensurate fractional…
Nonlinear Dynamical Regimes of Cosmological Frequency Combs
Madhurendra Mishra, Oem Trivedi, Adarsh Ganesan
We study the emergence of Cosmological Frequency Combs (CFCs) in a quintessence cosmology with an exponential potential using a dynamical systems formulation. Expressing the evolut…
Neuromorphic Computing Based on Parametrically-Driven Oscillators and Frequency Combs
Mahadev Sunil Kumar, Adarsh Ganesan
Parametrically driven oscillators provide a natural platform for neuromorphic computation, where nonlinear mode coupling and intrinsic dynamics enable both memory and high-dimensio…
Spontaneous Symmetry Breaking and Collective Higgs-Goldstone Dynamics in Solid-State Phononic Frequency Combs
Murtaza Rangwala, Adarsh Ganesan
We investigate the generation of phononic frequency combs arising from nonlinear coupling between Higgs-like and Goldstone-like phonon modes in hexagonal InMnO3. The Higgs-like mod…
