Theoretical Chemistry/Many-body Theory/Nanoscale Optics

Research in the Masiello group focuses on the development of novel, rigorous, and computationally tractable theoretical descriptions of the structure and dynamics of molecular, nanoscale, and mesoscopic systems, and their interactions with and through the electromagnetic field. Emphasis is placed, not upon performing ever larger computations with well-worn tools, but rather upon exploring uncharted directions through the formulation and implementation of new theoretical concepts. We aim to elucidate photochemistry in condensed-phase environments, plasmon-enhanced molecular sensing and plasmon-enhanced molecular spectroscopy, as well as a variety of problems in nanoscale optics by simultaneously blending together the most important aspects of both top-down and bottom-up descriptions of nature. Correct treatment of such requires that molecular-, nano-, and mesoscale phenomena all be addressed as a coherent whole, rather than a less-complete sum of three parts. We do this by utilizing molecular-electron propagator methods as well as explicitly time-dependent descriptions of quantum molecular dynamics coupled to continuum electrodynamics. We also employ purely classical electromagnetic theory, such as finite-difference, finite-element, and multipole methods, particularly in our collaborations with experimentalists working in related directions both at UW and elsewhere. Development of the software necessary to explore each of these theoretical concepts is an essential aspect of our research as we work in areas where few black-box applications exist.
