Ultrafast Magnetization Induced from Raman-Active Axial Chiral Phonons
Chuankun Huang, Alexander Milner, Jiaming Luo +8
Axial chiral phonons, which carry angular momentum and exhibit unusually large magnetic moments, provide a new degree of freedom for controlling the time-reversal symmetry and magn…
Optical centrifuge as a probe of strong dissipative coupling between a molecular rotor and superfluid helium
Ian MacPhail-Bartley, Sören E. Mahr, Cameron E. Peters +7
A macroscopic manifestation of superfluidity is that objects moving through liquid helium experience negligible friction below the Landau critical velocity. How this frictionless m…
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…
Rotational excitation of molecules in the regime of strong ro-vibrational coupling: Comparison between an optical centrifuge and a transform-limited pulse
J. M. García-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…
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…

A. A. Milner, A. Korobenko, V. Milner
Strong laser-induced magnetization of oxygen gas at room temperature and atmospheric pressure is achieved experimentally on the sub-nanosecond time scale. The method is based on co…
Adiabatic field-free alignment of asymmetric top molecules with an optical centrifuge
A. Korobenko, V. Milner
We use an optical centrifuge to align asymmetric top molecules by adiabatically spinning their most polarizable O-O axis. The effective centrifugal potential in the…
