Solitons - localised waves existing in nonlinear media may propagate without changing their shape and interact with each other as real particles. They are ubiquitous in nature - exist in any system exhibiting dispersion and nonlinearity. This project aims to study theoretically and experimentally properties of beams and solitons in non-local nonlinear systems. It will lay out theoretical foundations of the nonlocal solitons and demonstrate experimentally their unique features. This research will have an impact on understanding of the soliton phenomena in many fields including optics and matter waves, providing knowledge which may be subsequently transferred to practical technologies, such as in formation of optical circuits.

孤子是存在于非线性介质中的局域波，它可以在不改变形状的情况下传播，并作为真实的粒子相互作用。它们在自然界中无处不在-存在于任何表现出色散和非线性的系统中。本项目旨在从理论和实验上研究非局域非线性系统中光束和孤子的特性。它将奠定非局域孤子的理论基础，并在实验上证明其独特的功能。这项研究将对包括光学和物质波在内的许多领域中的孤子现象的理解产生影响，提供随后可能转移到实际技术中的知识，例如形成光学电路。
