Physics Calendar

The Physics calendar contains High Energy Theory events hosted by the Institute for Advanced Study and Princeton University. A condensed version of the calendar is sent to the general Physics mailing list on Friday afternoons. Reminder emails are sent the morning of the event. If you are a local faculty member, postdoc or graduate student and would like to be added to the general Physics mailing list, please contact Lisa Fleischer, lisa@ias.edu

IAS CMT/QFT Group Meeting

Lattice Realization of Topological Defects in 2D Conformal Field Theories (CFTs)
Madhav Sinha
11:00am|Bloomberg Lecture Hall (IAS)

Abstract: Topological defect lines in 2D CFTs have found resurgence in the context of categorical symmetries. In this talk, I will present the lattice realization of these for unitary Minimal Models. I will use Spin chains, such as Transverse Field...

Learning more from Teukolsky’s radial equation for quasi-normal modes
Lionel London
12:30pm|Princeton University, Jadwin Hall, Princeton Gravity Initiative, 4th Floor

Abstract:  Although solutions to Teukolsky’s radial equation play a key role in black hole perturbation theory, there are limitations in our understanding that obscure our practical use of e.g. quasi-normal mode overtone solutions. Towards...

IAS High Energy Theory Seminar

" “Unnecessary” Quantum Critical Points in Condensed Matter and Field Theory"
Senthil Todadri
2:30pm|Bloomberg Lecture Hall (IAS) & Zoom

Abstract: Quantum critical points usually separate two distinct phases of matter. Here I will discuss a class of "unnecessary" quantum critical points that lie within a single phase of matter (much like the liquid-gas transition, except that they...

On a $Z_3$ Topological Term in 10d Heterotic String Theories
Yuji Tachikawa
11:00am|Bloomberg Lecture Hall (IAS)

Abstract: I will compare the gravitational sectors of two 10d heterotic string theories, with E8 x E8 and Spin(32)/$Z_2$ gauge groups, and show that they differ by a subtle $Z_3$-valued topological term. I also discuss its relation to the...

IAS High Energy Theory Seminar

Aspects of Topological Symmetry, Holography, and Branes
Ibrahima Bah
11:00am|Bloomberg Lecture Hall (IAS) & Zoom

Abstract: In this talk I will discuss holographic duals of topological operators.  At low energy sugra, they can be realized by Page charge associated to Gauss law constraints. In the UV string theory, topological operators can be characterized by...

Bubbles of AdS as Black Hole Mimickers
Suvendu Giri
12:30pm|Princeton University, Jadwin Hall, Princeton Gravity Initiative, 4th Floor

Abstract: I will present a case for the striking resemblance between bubbles of anti-de Sitter (AdS) within Minkowski spacetime and black holes. These solutions of Einstein’s equations are motivated by high-energy physics and lack horizons. We will...
