Next Monday the BME Exotic Quantum Phases seminar series continues with this
Speaker: Andras Dombi (Wigner RCP)
Title: Collective self-trapping of atoms in a cavity
Time: Feb 1 Monday, 14:15
Location: online in Teams
Abstract: "We 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."
About the speaker: András obtained his PhD from ELTE in 2017, for theoretical
research on driven-dissipative quantum systems, supervised by Peter Domokos.
Since then, he is a postdoctoral research fellow at the Wigner Research
Centre for Physics, where he works on cold-atom experiments.
