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…
Information Is Not Physical: Possibility Spaces, Erasure, and the Structure of Unrealized Alternatives
Madhurendra Mishra
The slogan ``information is physical,'' introduced by Rolf Landauer and developed through quantum information theory and black-hole thermodynamics, has achieved near-axiomatic stat…
Cosmological Frequency Combs
Oem Trivedi, Madhurendra Mishra, Adarsh Ganesan
We identify a new class of time periodic attractor solutions in scalar field cosmology, which we term Cosmological Frequency Combs (CFC). These solutions arise in exponential quint…
