Factorized dispersion relations for two coupled systems
Alexander Figotin
We establish that the dispersion relations of any physical system composed of two coupled subsystems, governed by a space-time homogeneous Lagrangian, admit a factorized form G_{1}…

Exceptional Points in Gyrator-Based Circuit and Nonlinear High-Sensitivity Oscillator
Alireza Nikzamir, Kasra Rouhi, Alexander Figotin +1
We present a scheme for high-sensitive oscillators based on an exceptional point of degeneracy (EPD) in a circuit made of two LC resonators coupled by a gyrator. The frequency of o…
