“…As second instance, we analyzed the interaction between disorder and nonlinearity in Rhodamine with silica spheres [30] and in silica aerogel [33], where the randomness inhibits the DSWs occurrence. Moreover, we reviewed very recent works on generation of photonic wave breaking in chemical [34] and biological solutions [40], fields where DSWs are emerging as surprising tools, useful for sensing and control of extreme phenomena. Finally, we showed emergence of giant collective incoherent shock waves from random wave propagation in highly nonlocal media [37].…”

“…The study of optical effects in light propagation through chemical and biological solutions is a field of growing interest [34,40,54,[86][87][88][89], both from a linear and a nonlinear perspective. However, although observations of nonlinear optical phenomena in chemical and soft-matter systems can be found in a large literature [27,30,32,33,36,38,46,54,[90][91][92][93], and new experiments in chemical media are useful only if the material owns very specific properties, little is known about nonlinearity in biological fluids and the related literature is very recent [40,88].…”

“…Dispersive shock waves (DSWs) are rapidly oscillating solutions of hyperbolic partial differential equations that contrast the generation of multivalued regions through the formation of undular bores [1][2][3][4][5][6][7][8][9][10][11]. This class of phenomena was investigated in several physical fields, initially in shallow water waves [12] and ion-acoustic waves [13], then in oceanography [14], pulses propagation in photonic fibers [15,16], Bose-Einstein condensates [17][18][19][20][21][22], quantum liquids [23], photorefractive media [24], plasma physics [25], viscous fluids [26], and diffracting optical beams [5,[27][28][29][30][31][32][33][34][35][36][37][38][39][40].…”

Dispersive shock waves are fascinating phenomena occurring when nonlinearity overwhelms linear effects, such as dispersion and diffraction. Many features of shock waves are still under investigation, as the interplay with noninstantaneity in temporal pulses transmission and nonlocality in spatial beams propagation.Despite the rich and vast literature on nonlinear waves in optical Kerr media, spatial dispersive shock waves in nonlocal materials deserve further attention for their unconventional properties. Indeed, they have been investigated in colloidal matter, chemical physics and biophotonics, for sensing and control of extreme phenomena.Here we review the last developed theoretical models and recent optical experiments on spatial dispersive shock waves in nonlocal media. Moreover, we discuss observations in novel versatile materials relevant for soft matter and biology.

Dispersive shock waves in thermal optical media belong to the third-order nonlinear phenomena, whose intrinsic irreversibility is described by time asymmetric quantum mechanics. Recent studies demonstrated that nonlocal wave breaking evolves in an exponentially decaying dynamics ruled by the reversed harmonic oscillator, namely, the simplest irreversible quantum system in the rigged Hilbert spaces. The generalization of this theory to more complex scenarios is still an open question. In this work, we use a thermal third-order medium with an unprecedented giant Kerr coefficient, the M-Cresol/Nylon mixed solution, to access an extremely-nonlinear highly-nonlocal regime and realize anisotropic shock waves. We prove that a superposition of the Gamow vectors in an ad hoc rigged Hilbert space describes the nonlinear beam propagation beyond the shock point. Specifically, the resulting rigged Hilbert space is a tensorial product between the reversed and the standard harmonic oscillators spaces. The anisotropy turns out from the interaction of trapping and antitrapping potentials in perpendicular directions. Our work opens the way to a complete description of novel intriguing shock phenomena, and those mediated by extreme nonlinearities.
