Invited Speaker / Conférencier invité

Hollow-core photonic-crystal fibers (HCPCFs) loaded with atomic ensembles have been used in the past for demonstrations of strong optical nonlinearities arising from the tight transverse confinement of both photons and atoms. Integrating high-finesse optical resonators into HCPCFs would further enhance these nonlinearities and enable implementation of a variety of novel photonic devices, such...

We have demonstrated that a supersonic beam of methyl radicals (CH${}_3$) in the ground rotational state has been slowed down to standstill with a magnetic molecular decelerator, and successfully captured spatially in an anti-Helmholtz magnetic trap for longer than 1 sec. The trapped CH${}_3$ radicals have a mean translational temperature of about 200 mK with an estimated density of $>$ 5.0...

1844. Quantum simulation with laser-cooled trapped ions

Invited Speaker / Conférencier invité

Laser-cooled trapped ions are among the most versatile experimental platforms for the simulation of non-trivial quantum Hamiltonians. What distinguishes this platform from others is the extent to which it is experimentally possible to control this system at the level of individual particles and interactions between them. Internal states of these ions, such as hyperfine states, constitute well...

1901. Quantum coherent control of laser-kicked molecular rotors (DAMOPC Thesis Prize Winner)

Invited Speaker / Conférencier invité

Nonresonant rotational Raman excitation of linear molecules by periodic sequences of ultra-short laser pulses allows for the realization of a paradigm system - the quantum kicked rotor. This apparently simple physical system has drawn much interest within the last decades, especially due to its role in the field of quantum chaos. In the case of periodic kicking, the wave function of a quantum...
