Query: Engineering atomic polarization with microwave-assisted optical pumping   Polarized atomic ensembles play a crucial role in precision measurements. We
demonstrate a novel method of creating atomic polarization in an alkali vapor
in a continuous-wave regime. The method relies on a combination of optical
pumping by a laser beam and microwave transitions due to a cavity-enhanced
magnetic field. With this approach, atomic internal angular momentum can be
oriented along a static magnetic field at an arbitrary angle with respect to
the laser beam. Furthermore, the atomic polarization depends on the microwave
parameters, which can be used for microwave-to-optical transduction and
microwave-controlled nonlinear magneto-optical rotation.
