Technological advances in controlling and manipulating fluids have enabled the
experimental realization of acoustic analogues of gravitational black holes. A flowing fluid …

Abstract Reasoning by analogies permeates theoretical developments in physics and
astrophysics, motivated by the unreachable nature of many phenomena at play. For …

Gravity simulators are laboratory systems in which small excitations such as sound or
surface waves, behave as fields propagating on a curved spacetime geometry. The analogy …

Quantization effects of the nonlinear magnon-vortex interaction in ferromagnetic nanodisks
are studied. We show that the circular geometry twists the spin-wave fields with spiral phase …

The emergence of quantum mechanics and general relativity has transformed our
understanding of the natural world significantly. However, integrating these two theories …

Recent advances in electromagnetic nonreciprocity raise the question of how to engineer
the nonreciprocal electromagnetic response with geometrical approaches. In this Letter, we …

Nonlinear optics has been a very dynamic field of research with spectacular phenomena
discovered mainly after the invention of lasers. The combination of high intensity fields with …

The amplification of radiation by superradiance is a universal phenomenon observed in
numerous physical systems. We demonstrate that superradiant scattering generates …

Abstract The No Hair theorem in classical general relativity predicts that rotating black holes
are specified by the Kerr metric, which is uniquely identified by the mass and spin. However …

Abstract A novel (2+ 1)-dimensional nonlinear Schördinger equation is constructed from (1+
1)-dimensional Schördinger equation based on a deformation algorithm. The integrability of …
