The Tropical Division Problem and the Minkowski Factorization of Generalized Permutahedra
Robert Alexander Crowell
Given two tropical polynomials on , we provide a characterization for the existence of a factorization and the construction of . As a ramific…
Tropical Geometry and Mechanism Design
Robert Alexander Crowell, Ngoc Mai Tran
We develop a novel framework to construct and analyze finite valued, multidimensional mechanisms using tropical convex geometry. We geometrically characterize incentive compatibili…
Temperature and Humidity Dependence of Air Fluorescence Yield measured by AIRFLY
M. Ave
The fluorescence detection of ultra high energy cosmic rays requires a detailed knowledge of the fluorescence light emission from nitrogen molecules over a wide range of atmospheri…
Transient x-ray absorption spectroscopy of hydrated halogen atom
Christopher G. Elles, Ilya A. Shkrob, Robert A. Crowell +2
Time-resolved x-ray absorption spectroscopy monitors the transient species generated by one-photon detachment of an electron from aqueous bromide. Hydrated bromine atoms with a lif…
Title Excited state dynamics of liquid water: Insight from the dissociation reaction following two-photon excitation
Christopher G. Elles, Ilya A. Shkrob, Robert A. Crowell +1
We use transient absorption spectroscopy to monitor the ionization and dissociation products following two-photon excitation of pure liquid water. The two decay mechanisms occur wi…
Femtosecond electron and x-ray source based on laser wakefield accelerator
Dmitri A. Oulianov, Yuelin Li, Robert A. Crowell +4
A terawatt tabletop laser wakefield acceleration source of relativistic electrons has been developed in our Terawatt Ultrafast High Field Facility (TUHFF). The preliminary results…
