Non-equilibrium photocarriers in multilayer WSe2 injected by femtosecond laser pulses exhibit extraordinary nonlinear dynamics in the presence of intense THz fields. The THz absorption in optically excited WSe2 rises rapidly in the low THz field regime and gradually ramp up at high intensities. The strong THz pulses drive the photocarriers...
Polycyclic aromatic hydrocarbons (PAHs) are complex mixtures that form when organic matter is burned. Humans are primarily exposed to PAHs via air pollution from incomplete combustion of fossil fuels and biomass, such a motor vehicle exhaust, cigarette smoke, wood smoke, or industrial emissions; or via ingestion of PAHs bound to...
Changes in ocean conditions influenced by climatic fluctuations have lead to changes in individual species distributions, which alter the diversity, communities and species interactions across marine ecosystems worldwide. Assessing the species composition and identifying regions and habitats that can safeguard the persistence of biota are critically important. In this dissertation,...

In this dissertation, a series of studies in the field of terahertz (THz) science are presented, specifically using nonlinear THz spectroscopy. We exploit huge field enhancement and subwavelength confinement in plasmonic structures. There are three distinct projects which will be discussed: nonlinear THz spectroscopy using plasmonic induced transparency (PIT), THz-triggered...
This analysis concerns the life and scientific work of Henry
Augustus Rowland (1848-1901), organizer and the first chairman of
the physics department at The Johns Hopkins University in 1876.
Special materials used in this research included three pieces of
Rowland's experimental apparatus which are extant in the Smithsonian
Institution Division...
