In-situ adjoint protocols for nonlinear PT-symmetric self-optimizing machines
Zheming Li, Lucas J. Fernández-Alcázar, Zin Lin +1
Adjoint methods provide a powerful route for gradient-based optimization, but their physical implementation is obstructed in generic nonlinear systems because the adjoint dynamics…
Nonlinear Defect Theory of Thermalization in Complex Multimoded Systems
Emily Kabat, Alba Y. Ramos, Lucas J. Fernández-Alcázar +1
We show that a single nonlinear defect can thermalize an initial excitation towards a Rayleigh-Jeans (RJ) state in complex multimoded systems. The thermalization can be hindered by…
Optical Kinetic Theory of Nonlinear Multi-mode Photonic Networks
Arkady Kurnosov, Lucas J. Fernández-Alcázar, Alba Y. Ramos +2
Recent experimental developments in multimode nonlinear photonic circuits (MMNPC), have motivated the development of an optical thermodynamic theory that describes the equilibrium…
Noise Resilient Exceptional-Point Voltmeters based on Neuromorphic functionalities
Arunn Suntharalingam, Lucas Fernández-Alcázar, Rodion Kononchuck +1
Exceptional point degeneracies (EPD) of linear non-Hermitian systems have been recently utilized for hypersensitive sensing. This proposal exploits the sublinear response that the…
Adiabatic monoparametric autonomous motors enabled by self-induced nonconservative forces
Arkady Kurnosov, Lucas J. Fernández-Alcázar, Raúl Bustos-Marún +1
Archetypal motors produce work when two slowly varying degrees of freedom (DOF) move around a closed loop of finite area in the parameter space. Here, instead, we propose a simple…
