Title: GRMHD Simulations of Neutrino-Driven Winds From Proto-Neutron Stars Abstract: Formed in the aftermath of a core-collapse supernova or neutron star merger, hot proto-neutron stars (PNSs) launch neutrino-driven winds within milliseconds, with the winds themselves lasting for tens of seconds. The PNS wind has long been considered a potential site for the nucleosynthesis of heavy elements (Z>60) via the rapid neutron capture process (r-process). Previous work has found that such winds are not favorable for r-process element production. I will present results of general relativistic magnetohydrodynamic simulations of the PNS wind with weak interactions, advanced microphysics and neutrino absorption. I will discuss how physical mechanisms of rapid rotation and strong magnetic fields of a PNS may independently affect wind dynamics and how these effects may change r- process viability.

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.

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.

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.

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.

Title: GRMHD Simulations of Neutrino-Driven Winds From Proto-Neutron Stars Abstract: Formed in the aftermath of a core-collapse supernova or neutron star merger, hot proto-neutron stars (PNSs) launch neutrino-driven winds within milliseconds, with the winds themselves lasting for tens of seconds. The PNS wind has long been considered a potential site for the nucleosynthesis of heavy elements (Z>60) via the rapid neutron capture process (r-process). Previous work has found that such winds are not favorable for r-process element production. I will present results of general relativistic magnetohydrodynamic simulations of the PNS wind with weak interactions, advanced microphysics and neutrino absorption. I will discuss how physical mechanisms of rapid rotation and strong magnetic fields of a PNS may independently affect wind dynamics and how these effects may change r- process viability.

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.

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.
