Institute of Physics Polish Academy of Sciences

The formal colloquium of the Institute of Physics, Polish Academy of Sciences it the main ongoing periodic series of lectures in physics and related science, of interest to members of the Institute. It is held from 1977. Colloquium speakers are primarily domestic and foreign scholars of established reputation, but also less-known physicists with remarkable and current scientific achievements. The colloquium is held once a month from September to June, usually at 3:15 PM on the last Tuesday of the month in the Auditorium of the Institute of Physics. Colloquia are open to the public, and are preceded by a coffee/the reception at the Institute.

For future information about the colloquia, pleace contact Prof. Dr. hab. Leszek Sirko (, current chairman of the colloquium committee.


We are pleased to announce that on June 22th, 2021 (Tuesday) at 15:15 will be held on-line colloquium of the Institute of Physics PAS, in which:

Jean Dalibard

from Coll ge de France and Laboratoire Kastler Brossel,
will give a lecture entitled:

Topology and scale invariance in atomic Flatland

The Colloquium will be held using the ZOOM platform.

      In a 2D world, most transitions towards ordered states of matter like crystals or magnets would not occur because of the increased role of fluctuations. However, non-conventional topological transitions can still occur, as understood by Kosterlitz and Thouless (2016 Nobel prize). In this talk I will present some important features of Flatland physics explored with cold atomic gases, and connect them with other prominent topological properties of matter, such as quantum-Hall type phenomena.
