R. G. Herb Condensed Matter Seminar
Better Qubits with ALD and ALE
Time: 11:00 am
Place: Chamberlin 5310
Speaker: Dr. Russ Renzas, Oxford Instrumetns
Abstract: Quantum device losses are predominantly from surfaces and interfaces. Atomic layer deposition (ALD) enables tuneable low loss materials, such as superconducting nitrides with engineered crystallinity. Isotropic and anisotropic ALE are two distinct techniques which can each prepare and repair surfaces by removing native oxides prior to deposition or removing subsurface damage from RIE-induced subsurface amorphization and etchant incorporation. Isotropic ALE and ALD can also be combined in-situ to engineer interfaces prior to deposition and modify films. This talk will introduce these techniques through the lens of potential use cases in superconducting, photonic, and color center quantum device fabrication.

Physics Summer Fun
Indoor Recess
Time: 12:30 pm
Place: 5310 Chamberlin Hall
Speaker: Sharon Kahn
Abstract: We hope you’ll take a 20-30 minute break on (some/all) Wednesdays this summer (12:30-1pm) to come play together! For nice days, we’ve arranged to borrow some lawn games from the L&S dean’s office and will likely bring along a frisbee and/or a hackeysack, too.
In case of rain, we’ll meet indoors (5310 CH) for board games. Feel free to come play or just hang out!

NPAC (Nuclear/Particle/Astro/Cosmo) Forum
Measuring the neutrino-nucleon cross section at ultra-high energies: detailed forecasts for IceCube-Gen2
Time: 2:30 pm
Place:
Speaker: Mauricio Bustamante, Niels Bohr International Academy, Niels Bohr Institute, University of Copenhagen, Denmark
Abstract: Ultra-high-energy (UHE) neutrinos, energetic (> 100 PeV) but rare, have evaded detection for decades, but might soon be within the reach of upcoming neutrino telescopes. With them, we could measure for the first time UHE neutrino-matter interactions, allowing us to probe protons and neutrons deeper than before and to look for new high-energy physics. We present detailed measurement forecasts of the UHE neutrino-nucleon cross section, geared at radio-detection in IceCube-Gen2, with the aim of informing its science capabilities. We use state-of-the-art ingredients throughout: in the neutrino flux, in-Earth attenuation, Askaryan radio emission and propagation, detector modeling, and non-neutrino backgrounds. After 10 years, if at least a few tens of events are detected, we could measure the cross section at center-of-mass energies of 10-100 TeV for the first time, with a precision comparable to that of its theory prediction.
