By utilizing the theoretical tools of optical thermodynamics, we investigate thermalization in nonlinear disordered lattices beyond the diffusion regime. Even under extreme levels of disorder, we analytically predict the expected thermal value of ent

We develop a rigorous theoretical framework based on principles from statistical mechanics that allows one to predict the equilibrium response of classical non-Hermitian arrangements in the weakly nonlinear regime. In this respect, we demonstrate tha

Nonlinear highly multimode photonic systems are ubiquitous in optics. Yet, the sheer complexity arising from the action of nonlinearity in multimode environments has posed theoretical challenges in describing these systems. In this work, we deploy co

We show that the orbital angular momentum (OAM) of a light field can be thermalized in a nonlinear cylindrical multimode optical waveguide. We find, that upon thermal equilibrium, the maximization of the optical entropy leads to a generalized Rayleig

We demonstrate that, due to nonlinear interactions, the orbital angular momentum in a multimode optical fiber can reach a thermal equilibrium state that is characterized by a temperature and a generalized Rayleigh-Jeans distribution.

We present a new scaling law that relates the thermodynamic pressure with the electrodynamic forces in multimode nonlinear dielectric waveguides. Our results are in exact agreement with those obtained using the Maxwell stress tensor formalism.

We define the stringent coherence witness as an observable which has zero mean value for all of incoherent states and hence a nonzero mean value indicates the coherence. The existence of such witnesses are proved for any finite-dimension states. Not

We show that anomalous-even repulsive-force fields can be induced around high-contrast optical nanowaveguides. Interestingly the longitudinal scattering force attains a maximum value even within regions where the Poynting vector is negative.

We demonstrate that in nonlinear waveguide arrangements, the optical thermodynamic pressure results from the electrodynamic force exerted on the guiding interface and from an entropy growth term associated with an irreversible expansion.
