Nuclear and Particle Physics Seminar - Mr. Daniel Simons

Monday, September 27, 2021 2:30pm to 3:20pm
"Variations to the z-Expansion in the Form Factor Describing the Decay of B Mesons" Mr. Daniel Simons; Unviersity of Iowa We studied the decay rate of the particle decay $B^0 \rightarrow D^- \ell^+ \nu_{\ell}$ using data collected from the Belle Collaboration. In order to analyze this decay rate, we used three parameterizations of the form factor which describes the differential decay rate, the Caprini, Lellouch, and Neubert (CLN) parametrization, the Boyd, Grinstein, and Lebed (BGL)…

Operator Theory Seminar - Professor Ishan Ishan; Vanderbilt University

Tuesday, September 28, 2021 1:30pm to 2:20pm
Professor Ishan Ishan; Vanderbilt University Title: Von Neumann equivalence and weak forms of amenability   Abstract: The notion of von Neumann equivalence, which generalizes both measure equivalence and W*-equivalence, was introduced recently by Jesse Peterson, Lauren Ruth, and myself. We showed that many analytic properties, such as amenability, property (T), the Haagerup property, and proper proximality are preserved under von Neumann equivalence. In this talk, I will present my new work…

Math Physics Seminar - Professor David Berenstein; UCSB

Tuesday, September 28, 2021 2:30pm to 3:20pm
Professor David Berenstein; UCSB - "Bootstrapping Quantum mechanical systems in 1D" Abstract: I will show how one can solve numerically for the energy levels of certain quantum mechanical systems using a recursive plus unitarity method.  This method, called "bootstrap", uses the equations of motion of the system to find recursions between certain expectation values in an energy eigenstate.  Combined with positivity of the expectation value of any positive operator (what one calls unitarity),…

Physics & Astronomy Colloquium - Summer Undergraduate Research Colloquium

Tuesday, September 28, 2021 3:30pm to 4:30pm
Van Allen Hall
Summer Undergraduate Research Colloquium 28 SEP 2021, 301 VAN, 3:30p   (1) "Frequency Correlation Measurements of Wavefront-shaped Light in Round, Square, and Rectangular Multimode Fiber Core Geometries" by Mr. Hank Hammer Mentor: Prof. Ravi Uppu; Supported by a Wert Summer Research Grant Round-core Multimode fibers (MMFs) have been extensively investigated due to their applicability in endoscopic imaging and optical communication. However, alternative core geometries of MMF fibers (e.g.,…

Update - Mutel-Spangler Fest 2021 - postponed to Summer 2022

Saturday, October 2, 2021 (all day)
We have some updated information about our retirement celebration event for Professors Robert Mutel and Steven Spangler Because Robert and Steve and the rest of us are so looking forward to welcoming you to Iowa City and meeting you in person to celebrate their scientific careers, we have made the difficult decision to postpone this event from October 2, 2021 to Summer 2022. We will add updated information once the event is planned.
