HALT's Mission

HALT’s objective is to collaboratively develop new pathways in the understanding of complex turbulent behaviours of waves and coherent structures in light propagation through nonlinear optical media and atomic vapours in both one-dimensional (1D) and two-dimensional (2D) systems and draw connections to classical hydrodynamics. Through the novel experimental setups and the robust network between theoreticians and experimentalist, HALT will characterise universal behaviour of light turbulence in a variety of media and demonstrate a viable theoretical understanding with commercial potential. At the most fundamental level, developing a universal theoretical treatment of such problems will bring together the fields of nonlinear optics, condensed-matter fluids, and hydrodynamic turbulence into one. This is a truly pioneering project that will unify the approach to turbulence and cross the boundaries of wave-particle duality.

Research Objectives

  • RO1 Deliver an advanced wave-kinetics theoretical formalism to study the statistics and probability distributions of light waves in optical media and atomic vapours at weak nonlinearities.
  • RO2 Develop a novel kinetic description of optical coherent structures (solitons, collapses, and vortices) for strong optical turbulence.
  • RO3 Characterise the deterministic transition and instability of light towards optical turbulence regimes using sequential bifurcation theory approaches.
  • RO4 Apply novel experimental techniques and build new 1D and 2D optical (fibre lasers, liquid crystals, photo-refractive crystals) and condensed matter (atomic vapours) experiments to study weak optical turbulence and the initial formation of coherent structures.
  • RO5 Perform pioneering experiments to study strong optical turbulence regimes of many interacting solitons or vortices.

Knowledge Transfer Objectives

  • KTO1 Organise and deliver a series of workshops, training schools, and learning materials for establishing a long-lasting training and development network for ERs and ESRs in optical turbulence.
  • KTO2 To develop and strengthen research and innovation partnerships (i.e. joint research programme and co-supervision of research students) between the EU, Asia, Russia, and Brazil through international staff exchanges and networking activities.
  • KTO3 To strengthen EU research and innovation through enhanced training, mobility and career development of ERs and early ESRs.
  • KTO4 To fully embrace public engagement to communicate the research activities with the public and to champion to the public and society in general to promote the understanding of the elusive structure of turbulence.
  • KTO5 To work towards the sustainability of the collaboration through the development of project proposals for further funding.
  • KTO6 To effectively manage the Research and Innovation Staff Exchange programme for maximum knowledge exchange and career development for all the researchers.
