Absolute gravimeters based on falling corner-cube reflectors have been a cornerstone of geophysical research and exploration for decades. On the other hand, quantum gravimeters use matter-wave interferometry with a free-falling cloud of laser-cooled atoms to measure gravity down to the $10^{-9}$ g level. These instruments have demonstrated excellent sensitivity and stability over several...

Oral not-in-competition (Graduate Student) / Orale non-compétitive (Étudiant(e) du 2e ou 3e cycle)

Trapped ions are among the most precise hardware platforms for quantum information processing (QIP). Among various ion species, Barium ions are especially promising for scaling up quantum processors. They can be manipulated using visible light, for which advanced photonic devices such as fiber-based modulators are available, unlike the ultraviolet light required for most other ion species....

923. Nonlinear Optical Properties of Photoresponsive Self-Assembled Monolayers

Oral (Non-Student) / Orale (non-étudiant(e))

The field of smart materials, whose properties can be modified in response to an external stimulus, is currently experiencing rapid growth. Among the various stimuli available, light is particularly attractive for controlling materials, as it is readily accessible, biocompatible, non-invasive, and, most importantly, allows excitation with high spatial and temporal resolution. In this context,...

802. Photoelectron holography of a heteronuclear molecule

Dr Andre Staudte (Joint Laboratory for Attosecond Science of the National Research Council and the University of Ottawa)

Atomic, Molecular and Optical Physics, Canada / Physique atomique, moléculaire et photonique, Canada (DAMOPC-DPAMPC)

Oral (Non-Student) / Orale (non-étudiant(e))

We report on strong field photoelectron holography in heteronuclear hydrogen chloride (HCl), using coincidence resolved momentum imaging to access channel and orientation dependent electron dynamics. By detecting the photoelectron in coincidence with the ionic fragments, we unambiguously separate dissociative ionization pathways and reconstruct the molecular frame without requiring laser...

725. Control of molecular rotation in helium nanodroplets with an optical centrifuge

Dr Ian MacPhail-Bartley (University of British Columbia)

Atomic, Molecular and Optical Physics, Canada / Physique atomique, moléculaire et photonique, Canada (DAMOPC-DPAMPC)

Oral (Non-Student) / Orale (non-étudiant(e))

We experimentally demonstrate that the rotation of molecules embedded in helium nanodroplets can be controlled with an optical centrifuge, allowing for the study of molecular dynamics inside the strongly interacting many-body environment of superfluid helium at variable levels of rotational excitation. We show that forced in-field rotation of molecules is possible over a continuous range of...
