PUG Seminar - James Gurian
321 Whitmore
2022-12-09
Title: Zero Metallicity in Zero CPU Hours Abstract: I will begin with a pedagogical review of the theory of the formation of the first stars and the current open questions in the field. I will then present a new, analytic model for the formation of these stars which clarifies the essential physics. Despite its simplicity, this model agrees with the stellar mass predicted by expensive radiation-hydrodynamical simulations to within a factor of a few over the entire relevant parameter space.

2022-11-29
Speaker: Ivan Agullo (LSU) Title: On Entanglement in Quantum Field Theory Abstract: It is believed that even the simplest states in the simplest field theories are highly entangled. The main support for this statement comes from the Reeh-Schlieder theorem and calculations of entanglement entropy between a region of space and its complement. I will argue that these results do not provide much information about the entanglement between individual local degrees of freedom. I will then present a way of quantifying such entanglement and show that entanglement in field theory is significantly less ubiquitous than it is commonly believed.

GAPP: Development and Construction of the High-Energy Light Isotope Experiment
339 Davey and Zoom: https://psu.zoom.us/s/93737760341
2022-11-08
Lucas Beaufore, University of Chicago The High Energy Light Isotope eXperiment (HELIX) is a balloon-borne magnet spectrometer which seeks to address critical questions in cosmic ray physics by measuring the chemical and isotopic abundances of key light isotopes in the cosmic ray flux. One such measurement, that of the ratio of Be-10/Be-9, will provide strong discrimination between cosmic ray propagation models. In its first of two planned flights, HELIX will measure these abundances up to the ~3 GeV/n region. The instrument consists of a 1T superconducting magnet, a gas particle tracking system placed in the bore of the magnet, an aerogel RICH with a focal plane made of Silicon Photomultipliers (SiPMs), a scintillating fiber hodoscope, and a scintillating paddle time-of-flight system. This talk will cover the design, construction, and calibration of HELIX's novel RICH as well as a brief overview of HELIX's payload.
