(NEW DATE!) Ultracoherent nanomechanical resonators for quantum experiments and precision measurement
February 4, 2022 4:00 pm – 5:00 pm (CDT) Hawking Auditorium
(NEW DATE!) Ultracoherent nanomechanical resonators for quantum experiments and precision measurement

Speaker: Dalziel Wilson (University of Arizona)Host: Alexei Akimov

Nanomechanical resonators are exquisite force sensors and have recently been probed at the quantum limit using optical cavities. I’ll give a basic introduction to optomechanical force sensing and describe a new class of ultra-low-loss nanomechanical resonators that have given access to its Standard Quantum Limit. I'll focus in particular on [...]
Physical nature of information
February 10, 2022 4:00 pm – 5:00 pm (CDT) Hawking Auditorium
Physical nature of information

Speaker: Gregory Falkovich (Weizmann Institute)Host: Alexander Finkelstein

This is a a blackboard-chalk lecture on a quite elementary subject: how the second law of thermodynamics is getting trivial from the viewpoint of information theory.  It gives a panoramic overview of the applications of statistical physics / information theory, from bioinformatics to self-driving cars and turbulence theory. And a [...]
Lessons on Galaxy Transformations from Gaia
March 3, 2022 4:00 pm – 5:00 pm (CDT) Hawking Auditorium
Lessons on Galaxy Transformations from Gaia

Speaker: Vasily Belokurov (Cambridge University)Host: Louis Strigari

With its most recent data releases, European Space Agency’s Gaia mission revealed the fossilised record of a dramatic - and long suspected - accretion event in the distant past of our Galaxy. This head-on collision with a massive dwarf galaxy was a turning point in the evolution of the Milky [...]
Cosmic Reionization
March 8, 2022 4:00 pm – 5:00 pm (CDT) Hawking Auditorium
Cosmic Reionization

Speaker: Sultan Hassan (Flatiron Institute)Host: Lucas Macri

Reionization marks the last major global transition of the Universe, during which the birth of the first luminous cosmic structures gradually reionized the inter-galactic medium. Several observational efforts are devoted to detecting and constraining reionization on small and large scales. In this talk, I will discuss the key questions about [...]
The muon anomalous magnetic moment and the hunt for new physics
March 10, 2022 4:00 pm – 5:00 pm (CDT) Hawking Auditorium
The muon anomalous magnetic moment and the hunt for new physics

Speaker: Thomas Blum (University of Connecticut)Host: Rainer Fries

I will start with a brief history of the muon and its magnetic moment and then give an overview of the on-going experiment at Fermilab (E989). Next I’ll turn to the Standard Model calculation, including the hadronic contributions which contribute the largest uncertainty. I will focus on the difference between data-driven dispersive [...]
Massive Black Holes in Dwarf Galaxies
March 22, 2022 4:00 pm – 5:00 pm (CDT)
Massive Black Holes in Dwarf Galaxies

Speaker: Mallory Molina (Montana State University)Host: Lucas Macri

While supermassive black holes live in the heart of almost every massive galaxy, their origins remain unknown. Massive black holes residing in much smaller dwarf galaxies can shed light on the formation and evolution of supermassive black holes, but are notoriously difficult to detect. In this talk, I will present [...]
The Roman Space Telescope Galactic Bulge Time Domain Survey: Exoplanet Demographics and So Much More!
March 24, 2022 4:00 pm – 5:00 pm (CDT) Hawking Auditorium
The Roman Space Telescope Galactic Bulge Time Domain Survey: Exoplanet Demographics and So Much More!

Speaker: Scott Gaudi (Ohio State University)Host: Louis Strigari

The Nancy Grace Roman Space Telescope is the next NASA Astrophysics flagship mission scheduled to launch no later than May 2007.  Roman’s Galactic Bulge Time Domain Survey (GBTDS) will provide an unprecedented census of extrasolar cold and free-floating planets detected via gravitational microlensing of background stars.  The notional survey design [...]
Voltaic Cells: The Good (Faraday), the Bad (Volta), and the Ugly (Galvani)
March 31, 2022 4:00 pm – 5:00 pm (CDT) Hawking Auditorium
Voltaic Cells: The Good (Faraday), the Bad (Volta), and the Ugly (Galvani)

Speaker: Wayne Saslow (Texas A&M University)Host: Rainer Fries

We all use batteries constantly, but the usual discussion in physics textbooks — where one would expect to learn about voltaic cells, which in parallel and/or series combination constitute batteries — leaves many unresolved questions: (1) no real discussion of emf and why small AAA cells have the same emf as much [...]
Type Ia Supernovae and the Accelerating Universe (Note the Unusual Date!)
April 1, 2022 4:00 pm – 5:00 pm (CDT) Hawking Auditorium
Type Ia Supernovae and the Accelerating Universe (Note the Unusual Date!)

Speaker: Alexei FilippenkoHost: Nick Suntzeff

In 1998, two essentially independent research teams made a shocking announcement: the expansion of the Universe is accelerating rather than decelerating. The evidence for this Nobel-worthy conclusion was that the measured brightness of Type Ia supernovae (SN Ia, thermonuclear explosions of carbon-oxygen white dwarf stars) at a given redshift were [...]
From Stars to Cosmology
April 7, 2022 4:00 pm – 5:00 pm (CDT) Hawking Auditorium
From Stars to Cosmology

Speaker: Michael Boylan-Kolchin (University of Texas Austin)Host: Louis Strigari

Exquisitely detailed measurements of nearby collections of stars contain unique information about the Universe's expansion rate, the initial spectrum of cosmological density fluctuations, galaxy formation, and dark matter physics. In this talk, I will examine the role of globular star clusters as near-field windows into the physics of the Universe [...]
Pathways to Discovery in Astronomy and Astrophysics in the 2020's
April 14, 2022 4:00 pm – 5:00 pm (CDT) Hawking Auditorium
Pathways to Discovery in Astronomy and Astrophysics in the 2020’s

Speaker: Robert Kennicutt (Texas A&M University)

Recently the National Academy of Sciences completed a comprehensive decadal survey of research opportunities, strategic opportunities, and the state of the profession in astronomy and astrophysics.  The survey involved more than 130 members of the survey committee and its 13 sub-panels, and was informed by more than 860 white papers [...]
DISTINGUISHED LECTURE:  From Nonlinear Optics to High-Intensity Laser Physics
April 21, 2022 4:00 pm – 5:00 pm (CDT) Hawking Auditorium
DISTINGUISHED LECTURE: From Nonlinear Optics to High-Intensity Laser Physics

Speaker: Donna Strickland (University of Waterloo and Hagler Institute for Advanced Studies)Host: Marlan Scully, Director, Institute for Quantum Science and Engineering

The is the distinguished lecture for April 21, 4:00 PM in Hawking Auditorium (MIST MB01), with a reception in the MIST Penrose Plaza (first floor) at 3:15 PM.This event is sponsored by the Department of Physics and Astronomy, George P. and Cynthia Woods Mitchell Institute for Fundamental Physics and Astronomy, [...]
