### HET Seminar | Andrew Strominger, Harvard University | "Progress on Celestial Holography" | via Zoom

### PGI Virtual Seminar Series | Fani Dosopoulou, "The Merger History of Elliptical Galaxies: Mass Deficit"

Abstract: The structure and kinematics of galactic nuclei are fossil relics of the merger histories of galaxies and of the interaction between stars and SMBH binaries. Stars ejection during the SMBH binary evolution should reduce a galaxy’s central density and expand its core.

### Biophysics Seminar: Kranthi Kiran Mandadapu, University of California Berkeley: On the role of motility and glassy dynamics in growth of bacterial monolayers into the third dimension| Zoom

Many mature bacterial colonies and biofilms are complex three-dimensional (3D) structures. A key step in their developmental program is a transition from a two-dimensional (2D) monolayer into a 3D architecture.

### Gravity Group Lunch Seminar, Anne Gambrel | KICP, U. Chicago "The XFaster Power Spectrum and Likelihood Estimator and its Application to SPIDER"

Every analysis of cosmic microwave background observations faces the challenge of compressing large amounts of data into the comparatively tiny spaces of power spectra and cosmological parameters.

### Hamilton Colloquium Series, Cumrun Vafa, Harvard University, "The String Landscape and the Swampland"

String theory landscape of vacua point to new consistency conditions that a quantum gravitational system must satisfy. There are only a small number of quantum field theories that satisfy these conditions and all the rest belong to the `Swampland' which cannot be consistently coupled to gravity. In this talk I review some of these conditions...

### Condensed Matter Zoom Seminar | Titus Neupert,UZH | "Heating and blackhole dynamics in critical Floquet systems"

While driven interacting quantum matter is generically subject to heating and scrambling, certain classes of systems evade this paradigm. I will discuss such an exceptional class in periodically driven critical (1 + 1)-dimensional systems with a spatially modulated, but disorder-free time evolution operator.

### PRISM / PCCM Seminar Series Fall 2020

The Princeton Center for Complex Materials (PCCM) and the Princeton Institute for the Science and Technology of Materials (PRISM) co-sponsor a seminar series that is held on Wednesdays throughout the semester.

### PGI Virtual Seminar Series | Eliot Hijano Cubelos, "Where are BMS symmetries in the flat limit of AdS/CFT?"

Abstract: A holographic description of physics in Minkowski space is still elusive. A tempting approach is to implement a flat limit from AdS/CFT. Such a limit has not properly been understood, even at the level of the symmetries of the theory; How do BMS symmetries emerge from the flat limit of the asymptotic symmetries of anti-de Sitter space...

### Biophysics Seminar: Seppe Kuehn, University of Chicago| A sparse mapping from structure to function in microbial communities|Zoom

The metabolic function of microbial communities emerges through a complex hierarchy of genome-encoded processes, from gene expression to interactions between diverse taxa. Therefore, a central challenge for microbial ecology is deciphering how genomic structure determines metabolic function in communities.

### HET Seminar | Sridip Pal, Member, School of Natural Sciences, IAS | "Universality in Asymptotic Bounds and their Saturation in 2D CFT" | via Zoom

### Gravity Group Seminar | Speakers TBA "The Simons Observatory Instrument: Status of Ongoing Research at Princeton"

The Simons Observatory (SO) will be a cosmic microwave background (CMB) survey experiment with four small-aperture telescopes (SATs) and one large-aperture telescope, which will observe from the Atacama Desert in Chile.

### Hamilton Colloquium Series, Charles M Marcus, NBI, "The Search for Fractional Statistics"

Panel discussion with Duncan Haldane (Princeton), Michael Manfra (Purdue) and Gwendal Feve (ENS)

### Condensed Matter Zoom Seminar | Jiaxin Yin | "Tunneling into emergent topological matter"

The search for topological matter is evolving towards strongly interacting systems including topological magnets and superconductors, where novel effects emerge from the quantum level interplay between geometry, correlation, and topology.

### PRISM / PCCM Seminar Series Fall 2020

The Princeton Center for Complex Materials (PCCM) and the Princeton Institute for the Science and Technology of Materials (PRISM) co-sponsor a seminar series that is held on Wednesdays throughout the semester.

### Hamilton Colloquium Series, Monika Schleier-Smith, Stanford University, "Choreographing Quantum Spin Dynamics with Light"

The power of quantum information lies in its capacity to be non-local, encoded in correlations among two, three, or many entangled particles. Yet our ability to produce, understand, and exploit such correlations is hampered by the fact that the interactions between particles and ordinarily local.

### Condensed Matter Zoom Seminar | Johnpierre Paglione, U of MD | "Exotic superconductivity in nearly ferromagnetic UTe2"

Topological superconductivity has attracted great interest in condensed matter physics because of its potential applications in quantum computing. Spin-triplet superconductors are one promising class that can host the topological excitations of interest, but experimental realizations are few and far between.
