Coherent spectroscopy of collective excitations in superfluid helium far from equilibrium
Gabriel Voith, Alexander A. Milner, Michael J. Desrochers +2
Ultrafast dynamics of collective excitations in superfluids remains largely unexplored beyond the roton region of the Landau excitation spectrum, despite the importance of such dyn…
Ultraslow optical centrifuge with arbitrarily low rotational acceleration
Kevin Wang, Ian MacPhail-Bartley, Cameron E. Peters +1
We outline the design and characterization of a laser pulse shaper, which creates an ``ultraslow optical centrifuge'' - a linearly polarized field whose polarization vector rotates…
Rotational excitation of molecules in the regime of strong ro-vibrational coupling: Comparison between an optical centrifuge and a transform-limited pulse
J. M. GarcÃa-Garrido, V. Milner, C. P. Koch +1
We investigate theoretically the ability of an optical centrifuge - a laser pulse whose linear polarization is rotating at an accelerated rate, to control molecular rotation in the…
Control of molecular rotation in helium nanodroplets with an optical centrifuge
Ian MacPhail-Bartley, Alexander A. Milner, Frank Stienkemeier +1
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 dynam…
An optical centrifuge with zero rotational acceleration
K. Wang, A. Hardikar, A. A. Milner +1
An optical centrifuge is a laser pulse which enables controlled rotational excitation of molecules. Centrifuged molecules rotating with well-defined angular frequencies are ideal c…
