Chaos & Complex Systems Seminar
Frac sand and related natural resources in Wisconsin
Time: 12:05 pm - 1:00 pm
Place: 4274 Chamberlin Hall (Refreshments will be served)
Speaker: Jay Zambito, UW Department of Geoscience
Abstract: Wisconsin has some of the best frac sand in the world, and since 2011 the state has seen a large increase in frac sand mines, processing plants, and rail loading facilities. This talk will provide information on what frac sand is, how it is used, why it is being mined in Wisconsin, and its connection to other natural resources.

Theory Seminar (High Energy/Cosmology)
New physics in Higgs kinematic distributions
Time: 3:00 pm - 4:00 pm
Place: 5280 Chamberlin Hall
Speaker: Adam Martin, University of Notre Dame
Abstract: In this talk I discuss how Higgs distributions, rather than rates alone, can uncover physics beyond the Standard Model. As examples, I explore Higgs plus jet production and Higgses produced in association with bottom or top quarks

R. G. Herb Condensed Matter Seminar
Modes are Modes: Parametric quantum information processing in superconducting circuits
Time: 10:00 am
Place: 5310 Chamberlin Hall
Speaker: Jose Aumentado , NIST, Boulder
Abstract: I will give a brief overview of our work in utilizing parametric coupling to process quantum information in superconducting circuits. In the 2nd half, I will then discuss some of our ideas in continuously coupled multi-mode parametric circuits, and how expansion of the mode basis beyond the traditional two modes (signal+idler) can provide for more complex behavior including, for instance, the possibility of building in directionality, impedance matching, and even modifiying the gain-bandwidth constraint. As a simple example, I will discuss a 3-mode amplifier which has been realized in our group in an optomechanical circuit.

Astronomy Colloquium
The First Results From CHAOS: The Chemical Abundances Of Spirals Project
Time: 3:30 pm - 5:00 pm
Place: 4421 Sterling Hall
Speaker: Danielle Berg, Center for Gravitation, Cosmology and Astrophysics, UW Milwaukee
Abstract: "The CHemical Abundances of Spirals (CHAOS) project seeks to establish a broader understanding of the chemical evolution of spiral galaxies in general. CHAOS harnesses the combined power of the Large Binocular Telescope (LBT) with the large spectral range and sensitivity of the Multi Object Double Spectrographs (MODS) to observe “direct” abundances in a large sample of spiral galaxy H II regions. In this manner, we measure the largest sample of the highest quality spectra to date in NGC 628, with one or more temperature sensitive auroral lines ([O III] λ4363, [N II] λ5755, and [S III]λ6312) being observed at a strength of 3σ or greater in 45 H II regions. This high quality, homogeneous dataset allow us to examine trends in physical conditions and abundances with an unprecedented statistical significance. This analysis provided some atypical results. The comparison of derived temperatures where more than one auroral line is observed in an H II region demonstrates, unexpectedly, that temperatures based on [S III] λ6312 and [N II] λ5755 are consistent, while those based on [O II] λλ7320,7330 and [O III] λ4363 can often show large discrepancies. Understanding these temperature discrepancies will be a major goal for the CHAOS project. We examine the relative alpha-element abundances, as well as measure the O/H and N/O gradients in NGC 628. We find a large dispersion in O/H and posit that this dispersion represents an upper limit to the true dispersion in O/H at a given radius and that some of that dispersion is due to systematic uncertainties arising from temperature measurements.”

Physics Department Colloquium
Quantum Entanglement for Fun and Profit: 101 Uses for Schroedinger's Cat
Time: 3:30 pm - 4:30 pm
Place: 2241 Chamberlin Hall (coffee at 4:30 pm)
Speaker: Paul Kwiat, University of Illinois at Urbana-Champaign
Abstract: Nearly 80 years after Schroedinger described entanglement as the quintessential nonclassical phenomenon, and 50 years after Bell showed the inconsistency of quantum correlations with local realism, the quantum information revolution seeks to use its almost magical properties to enable new feats in information processing. As we shall see, entanglement can now be produced at high rates with exquisite precision, enabling unprecedented tests of nonlocality and such feats as quantum cryptography and teleportation. I will describe some of these miracles, and our investigations into how the usual benefits can be further extended, by using more complex quantum states (e.g., hyper-entanglement ). Time and appetites permitting, I may give a brief lesson in quantum cooking.
