Wave turbulence in self-gravitating Bose gases and nonlocal nonlinear optics

Abstract: We develop the theory of weak wave turbulence in systems described by the Schrödinger-Helmholtz equations in two and three dimensions. This model contains as limits both the familiar cubic nonlinear Schrödinger equation, and the Schrödinger-Newton equations. The latter, in three dimensions, are a nonrelativistic model of fuzzy dark matter which has a nonlocal gravitational self-potential, and in two dimensions they describe nonlocal nonlinear optics in the paraxial approximation. We show that in the weakly non… Show more

“…There is a surge of interest in studying analogue gravity phenomena in optical laboratory-based experiments that recreate some aspects of the full gravitational system [32][33][34][35][36][37]. Gravity being inherently nonlinear and nonlocal, the hidden coherent soliton states predicted here could be observed in highly nonlocal nonlinear optics experiments [38][39][40][41][42][43][44][45][46][47], or alternatively in dipolar Bose-Einstein condensates [48].…”
