Welcome to the website of the quantum gases group of LKB – Collège de France
Our group explores quantum matter using ultracold atoms systems. Our main activities focus on superfluidity, phase transitions, topological matter, quantum optics, spinor dynamics or non-hermitian physics. We operate several experimental apparatus dedicated to 2D Bose gases, large-spin dysprosium gases, quantum mixtures and optical lattices.
Our team is a member of Laboratoire Kastler Brossel and our labs are located at Collège de France, Paris.
