ACAT2027

Scientific Programme

ACAT 2027 will feature a dynamic scientific program centered around plenary sessions, parallel tracks & poster sessions. It is designed to encourage exchange across disciplines and foster in-person interaction between communities working at the intersection of physics, computing, and artificial intelligence.

Nobel Symposium

For the first time in ACAT, the 2027 edition will feature a Nobel Symposium and a series of four parallel Mini-Symposia addressing timely and emerging topics at the intersection of physics, computing, and artificial intelligence. These sessions will provide opportunities for focused discussions around selected scientific themes, composed of few speakers and a convener leading the discussion, bringing together researchers from different communities and disciplines.

• Mini-Symposia

  Topic and details to be announced following the selection of submitted proposals, allowing the programme to reflect the interests and emerging directions of the ACAT community led. More information how to apply is available on the Mini-Symposia page
