Meson Photo-Couplings From Lattice Quantum Chromodynamics
… in general, contain information about many radiative transition matrix elements simultaneously. We develop and implement the technology necessary to isolate a single matrix element via the use of optimized operators, operators designed to interpolate a single meson eigenstate, which are …

A variational approach to hadron structure in lattice QCD
… relevant to a single eigenstate or eigenstate transition, we show that this method is both an effective way to remove excited state contamination from the study of ground state systems and an effective framework through which one can study the structure of hadronic excitations. We begin with an …

R-matrix calculations in support of diagnostics for fusion and astrophysical plasmas
… Dirac R-matrix codes. We then employ collisional-radiative models, exploiting results from both the atomic structure and R-matrix calculations, to provide us with valuable diagnostic information about the plasma. The underlying theory of these atomic structure, scattering, and …

Homodyne High-harmonic Spectroscopy: Coherent Imaging of a Unimolecular Chemical Reaction
… back to rest in its initial ground state via a radiative transition. The emitted attosecond (atto=10^-18) XUV light pulse carries all the information (polarization, amplitude and phase) about the photorecombination continuum-to-ground transition dipolar field. Photorecombination is related to …
