This is the homepage for the Budapest integrability seminars, which are online seminars, broadcast through MS Teams.
Budapest has now three research groups in the field of integrability (at BME, Wigner, and Eötvös). Due to the COVID restrictions we started to hold online seminars in 2020. We invite both local and international speakers, the talks are on wednesday 2pm sharp (Budapest time).
In the seminar series we cover multiple topics, primarily integrability and its applications, but also more general topics from many body physics to quantum information theory.
We opearate an email list for the announcement of the talks. You can subscribe with a gmail account by sending a mail to
budapest-integrability-events+subscribe@googlegroups.com
If you wish to subscribe with a non-gmail account, please send an email to pozsgay.balazs who is using gmail.
