OXFORD PLASMA THEORY GROUP
THE LEVERHULME TRUST INTERNATIONAL NETWORK ON MAGNETISED PLASMA TURBULENCE

PLASMA SEMINARS AND GROUP MEETINGS

The style of the seminars will be informal/chaotic/interactive, following the established tradition. The format of the presentations can be a tutorial on a topic of interest, a report on just completed/ongoing/just starting/potentially interesting research projects, a literature review, a lecture by a passing visitor or anything else worthwhile that anyone cares to suggest. The speakers will be interrupted freely and asked to defend themselves.
For background reading, only the most relevant or the most recent references are posted; please follow the paper trail from there.

The schedule is subject to change on short notice, but what you see posted here is always up to date; the seminars are also announced via the department's seminar server (group meetings are not). Please email Alex Schekochihin if you would like to receive email updates on these seminars.

Financial support for those coming from outside Oxford is available: travel will be paid by the Leverhulme Network grant. If a guest room is required in Oxford, this can be arranged, although might prove difficult if requested on short notice. The grant can also support overseas visitors --- suggestions about whom to invite are welcome.

"Group meetings to discuss current affairs" will discuss current affairs (ongoing projects, new litearture etc.). They are open to all members of the Oxford Plasma Theory Group (which is easy to join). While some expected contributions are pre-announced, everything is TBC and people wishing their work to be discussed can volunteer contributions without prior notice. Unlike for the seminars, there will not be full-spam-list email reminders of the group meetings.
