Abstract: We use intense vector beams to generate high harmonics or to create solenoidal currents in solids or gases. We predict THz magnetic fields reaching the scale of those only available at user facilities.
In the visible and infrared we can transform Gaussian beams into beams with spatially dependent polarization and/or phase structures. Orbital angular momentum is given to a beam...

Photons emitted from atomic transitions may be twisted; angular momentum opposite to the atom's internal configuration change is distributed between the photon's spin (polarization) and orbital angular momentum depending on the angle of observation. Photons twisted perpendicular to their angle of observation propagate through an aperture at an angle, and measuring the photon's displacement at...

We measure the current dissipation rate of fermionic ultracold atoms in an optical lattice. A quantum gas microscope enables high-resolution fluorescence imaging of atoms pinned to lattice sites. Using micron-scale periodic displacements of an underlying harmonic potential to provide an oscillating uniform force, we measure the global current response of the atoms for multiple frequencies...

Plasmon-based solar energy conversion relies on absorption and charge separation at rectifying, metal/dielectric interfaces. Hot electrons produced through plasmon decay can undergo internal photoemission (IPE) and injection into an adjacent dielectric material, generating useful photo-current and -voltage determined by the metal/dielectric material pair. Here, we describe our work to...

The tune-out wavelength is usually viewed a zero in the frequency-dependent polarizability [1,2]. This view is appropriate for an atom in an optical lattice that is fixed in space. However, for an atom interacting with a traveling plane wave from a laser, it is more appropriate to view the tune-out wavelength as a zero in the Rayleigh scattering cross section for coherent scattering. In...
