Layering — A structure formation mechanism in oceans, atmospheres, active fluids and plasmas

Workshop theme

Fluid and plasma dynamics often manifest the spontaneous formation of ‘staircases’ or layered structures — arrays of finite homogenized domains separated by sharp gradients, which act as transport barriers. Anti-diffusion is a common route to staircase formation. Layered states exert a critical control on transport and dynamics in:

i) Geophysical fluids — for example, potential vorticity staircases are associated with jets.

ii) Density-stratified fluids — an important application where ‘self-sharpening’ effects are poorly understood.

iii) Double-diffusive convection — which occurs in planetary atmospheres, oceans and stellar interiors. Double-diffusive convection is especially important in many climate applications.

iv) Plasmas — where staircases in magnetized plasmas constitute a new confinement state, and are related to internal transport barrier formation.

v) Active fluids — where anti-diffusion and layering are important in a wide variety of applications, including biological systems.

The workshop will foster dialogue and interaction among oceanographers, plasma physicists, geophysical and astrophysical fluid dynamicists, soft-condensed-matter physicists, applied mathematicians and biophysicists. The central aim of the workshop is cross-fertilization, formation of new collaborations, and progress toward collective understanding.

Meals

Lunch

Lunch will be served at Churchill College. Attendees will be provided with lunch vouchers for 2 courses and 1 drink. Timings will be confirmed with the timetable.

Evening Meal

Participants are free to make their own arrangements for dinner.

Formal Dinner

The Formal Dinner will be held at Corpus Christi College on Thursday 18th January at 19:30.
