SZFI SeminarDombi AndrásWigner RCP SZFICollective self-trapping of atoms in a
cavityTuesday, 8 December 2020, 10:00, video conference,
https://letsmeet.wigner.hu/szeminariumWe experimentally demonstrate optical
dipole trapping of a cloud of cold atoms by means of a dynamically coupled
mode of a high-finesse cavity. We show that the trap requires a collective
action of the atoms, i.e. a single atom would not be trapped under the same
laser drive conditions. The atoms pull the frequency of the mode closer to
resonance, thereby allowing the necessary light intensity for trapping into
the cavity. The back-action of the atoms on the trapping light mode is also
manifested by the non-exponential collapse of the trap. Minden
