The ICOLS bi-annual conference series started in Vail, Colorado, in 1973. Since then, 25 editions have been held the latest of which, ICOLS2019 and ICOLS2023, took place in Queenstown, New Zealand, and Estes Park, Colorado.
The 26th edition is back to Italy 30 years after TWICOLS ’95 in Capri when the first experimental evidence of Bose-Einstein condensation of ultracold atoms was announced.
Following the tradition of previous meetings, the scope of this Conference is to bring together scientists working in the broad area of laser spectroscopy and related topics in atomic, molecular, optical physics and other disciplines, including applications, to provide a unique opportunity to exchange leading-edge scientific news and ideas, thus stimulating novel research activities.
The topics cover a wide range of exciting physics, such as precision tests of fundamental symmetries with atoms and molecules, atomic clocks, atom interferometry, quantum many-body physics with ultra-cold atoms, ultra-fast atomic and molecular dynamics, mesoscopic and artificial atoms, quantum optics, and quantum information science.
