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...

Each week, we hold a relatively informal seminar/discussion series with an emphasis on extra-galactic and large-scale structure astrophysics.

During Galread a leader/visitor presents a recent paper to the discussion group. The PDF of the paper is...

I will discuss an adaptation of Gromov's ideal-valued measures to symplectic topology. It leads to a unified viewpoint at three "big fiber theorems": the Centerpoint Theorem in combinatorial geometry, the Maximal Fiber Inequality in topology, and...

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...

Asteroseismology uses the natural oscillation modes of stars to study their interiors. The wonderfully precise measurements by NASA's Kepler and TESS missions are ideal data sources for the technique. These space telescopes have been monitoring the...
