### Condensed Matter Seminar - "Interplay of correlations and topology in the narrow bands of twisted bilayer graphene" Oskar Vafek, Florida State University

I will present an overview of the current theoretical understanding of the remarkable phenomenology of the twisted bilayer graphene (TBG) near the magic angle. This includes the early insights obtained using the 2D exponentially localized Wannier basis[1] which revealed a qualitative difference between the effect of the...

This seminar will be presented **in-person in Wolfensohn Hall at the IAS and on Zoom. **

### PGI Fall Seminar Series|Rita Teixeira da Costa|Princeton University|"The Teukolsky Equation on Kerr Black Hole Spacetimes"

Abstract:

The Teukolsky master equations describe the linear behavior of extremal perturbations of the Kerr black hole family.

### Biophysics Seminar: Andrej Kosmrlj| Princeton University: Pattern formation in biological systems via mechanical instabilities and phase separation

Pattern formation is ubiquitous in biological systems. While pattern formations are often associated with Turing-like reaction-diffusion systems, biology also exploits many other mechanisms such as mechanical instabilities and phase separation.

### FPO - Preethi Pallegar - "Symmetries and Large N Limits of Majorana Fermion Models"

In this thesis, we study generalizations of well-known Majorana fermion models, including the SYK model and the Klebanov-Tarnopolsky tensor model. The models are compared at finite and large N, where we find that the models simplify considerably and can even become solvable.

### FPO - Seong Woo Oh - "Cryogen-Free Scanning Probe Microscopy in Silicon Device Physics at milli-Kelvin temperatures"

Spin qubits housed in silicon quantum dots are rapidly emerging as a viable quantum computing platform. In recent years, there have been single- and two-qubit gate demonstrations, which showed high fidelities to the extent that implementing quantum error correction codes appears to be within reach.

### FPO - Ho Tat Lam - "On Symmetries, Anomalies and Their Generalizations"

This dissertation explores various generalizations of global symmetries and ’t Hooft anomalies. Chapter two is based on work with Po-Shen Hsin and Nathan Seiberg [1]. It is dedicated to the study of one-form global symmetries in three and four dimensions. We investigate their physical implications, classify their ’t Hooft anomalies and analyze...

### FPO - Sarah Marie Bruno - "Focal Plane Development for Observations of the Cosmic Microwave Background with the Simons Observatory"

A promising avenue for studying the origin and evolution of the universe is to measure the Cosmic Microwave Background (CMB), the thermal radiation remaining from the Big Bang after billions of years of expansion. Today, this remnant takes the form of an extraordinarily uniform thermal blackbody of ~2.7 K in temperature.
