Polsko-francuskie sympozjum: postępy w fizyce ultrazimnej materii


Polish-French Symposium: Developments in the physics of ultracold matter

Paris, 01 Jul  2021 -  03 Jul  2021


Scientific Center in Paris, Polish Academy of Sciences
74, rue Lauriston – 75116 Paris

The symposium addresses the physics of ultracold gases and their applications in quantum technology.
The field is developing dynamically in both theoretical and experimental basic research. It is possible to manipulate a single atom or a group of several atoms on demand. The observation of characteristic quantities, previously impossible to measure, is now available. Interesting novel directions of theoretical research emerge inspired by the advances in experimental techniques and unexpected results, as the observation of quantum droplets.

The main topics of the mini-symposium are:

  • new phases of matter arising from nonlocal interactions,
  • nonlinear phenomena,
  • computational methods used in modeling of quantum many-body systems,
  • research on quantum coherence of ultracold atoms,
  • time crystals,
  • creation of entangled states of ultracold atoms.
