Condensed, Soft & Living Matter Seminar: Geometry for Many Body Systems: Geometrical Sum Rules and Lattice Models

Jie Wang (Temple University)
- David Rittenhouse Laboratory, A8

Geometry describes how quantum states change locally in parameter space and governs many important physical phenomena, including many-body phases and their responses. The classic example of zero-temperature…



Astrophysics Seminar: High-redshift star formation under the cosmic microscope with SPT+ALMA+JWST

Joaquin Vieira (UIUC)
- David Rittenhouse Laboratory, 4E19



Condensed, Soft & Living Matter Seminar: Light Probes and Structural Color in Dense Complex Media: Lost Between Single and Multiple Scattering

Frank Scheffold (University of Fribourg, Switzerland)
- David Rittenhouse Laboratory, 2N3

Visible light can be used to probe dense, complex media such as colloidal suspensions or compact sediments. In liquid samples, the temporal fluctuations contain information about the local viscoelastic…



High Energy Theory Seminar: The Quantum Universe from Quantum Gravity

Yasunori Nomura (Berkeley)
- David Rittenhouse Laboratory, 3W2

I will discuss issues involved in formulating a quantum theory of the universe, including nonperturbative aspects of quantum gravity. In particular, I will explore how to pose physically meaningful questions in…



Rittenhouse Lecture: Measuring Cosmic Sound with the Dark Energy Spectroscopic Instrument

Daniel Eisenstein (Harvard University)
- David Rittenhouse Laboratory, A8

I will describe recent results from the Dark Energy Spectroscopic Instrument (DESI) on the measurement of the cosmic distance scale with the baryon acoustic oscillation (BAO) method and its resulting…



High Energy Theory Seminar: Love numbers for astrophysical compact objects in theories beyond General Relativity

Kent Yagi (University of Virginia)
- David Rittenhouse Laboratory, 3W2

One can probe nuclear physics with gravitational waves from a binary neutron star merger through measurements of a tidal Love number. The latter is a linear response coefficient of the stellar quadrupole moment…



Condensed, Soft & Living Matter Seminar: Physical approaches to understanding and predicting viral evolution

John Barton (University of Pittsburgh)
- David Rittenhouse Laboratory, A8

How predictable is evolution? This question has inspired biological research for decades, but it remains challenging to address quantitatively. In this talk, I will describe how we adapted methods from…



Astrophysics Seminar: Why a tiny neutrino particle inspired me to simulate and reconstruct the entire Universe

Adrian Bayer (Flatiron)
- David Rittenhouse Laboratory, 4E19

Massive neutrinos suppress the growth of cosmic structure on small, non-linear scales, making it crucial to go beyond a traditional power spectrum analysis to tighten constraints on their mass.
