We present a novel mechanism to control wave packet collapse in nonlinear media. This method utilizes self-generated nonlocal nonlinearities via wave rectification to tailor collapse dynamics.

Area of Science:

  • Nonlinear optics
  • Wave dynamics
  • Mathematical physics

Background:

  • Wave packet collapse is a critical phenomenon in nonlinear media.
  • Controlling collapse is essential for applications in optics and Bose-Einstein condensates.
  • Nonlinear Schrödinger equations describe wave packet dynamics.

Purpose of the Study:

  • To propose a mechanism for controlling wave packet collapse.
  • To investigate the role of self-generated nonlinearities.
  • To tailor and arrest collapse in nonlinear media.

Main Methods:

  • Developing a theoretical model based on nonlocal two-dimensional nonlinear Schrödinger-like equations.
  • Incorporating wave rectification to induce self-generating nonlocal nonlinearities.
