Phase control of interfering stimulated Raman pathways in the XUV regime

Abstract Coherent control uses interference between quantum pathways to enhance or suppress transitions to a target quantum state. In stimulated Raman excitation, such control can be achieved through interference between two indistinguishable pathways connecting the same initial...

Variance reduction for forces and pressure in variational Monte Carlo

We present simple and practical strategies to reduce the variance of Monte Carlo estimators. Our focus is on variational Monte Carlo calculations of atomic forces and pressure in electronic systems, although we show that the underlying ideas apply more broadly to other observable...

Surface Plasmons in the Continuum

Abstract The interest to foster plasmonic applications at energies in the ultraviolet has escalated research initiatives in clusters of unconventional plasmonic materials like aluminum and indium, for which the surface-plasmon resonance appears above the ionization potential. Nat...

Automated Spin‐Assisted Layer‐by‐Layer Epitaxy Produces Highly Oriented Mixed‐Linker MOF Thin Films

ABSTRACT Control over crystallographic orientation in metal‐organic framework (MOF) thin films is crucial for exploiting their anisotropic properties in sensing, catalysis, and separation. Achieving reproducible, highly oriented films remains challenging, especially for mixed‐lin...

Transmission diffuse EUV scattering by nanoscale Lamb waves in thin membranes

We report time-resolved diffuse extreme ultraviolet (EUV) scattering measurements of optically excited acoustic waves in thin Ti/SiN bilayers in transmission geometry. Following femtosecond optical excitation, the EUV diffuse scattering signal yields circular fringe patterns evol...
