October 17, 2022 9:00 amI will explain a new type of holographic dualities between n+1D topological orders with a chosen boundary condition and nD (potentially gapless) quantum liquids. It is based on the idea of topological Wick...

Gauge Theory and Topology Seminar, SEMINARS
October 14, 2022 3:30 pmRepresentations of 3-manifold groups into groups such as SU(2) and SL(2,C) have been actively studied for decades. Many topological invariants are defined by considering these representations, such as the Casson...

October 14, 2022 11:00 amSolutions of the algebraic Bethe ansatz for quantum magnet chains are, generally, multivalued functions of the parameters of the integrable system. I will explain how to compute some monodromies of solutions...

ALGEBRAIC DYNAMICS, SEMINARS
October 13, 2022 4:00 pm I will discuss joint work with V. Alexeev which builds a correspondence between degenerations of polarized K3 surfaces and integral-affine structures on the 2-sphere containing a weighted balanced graph. Under...

October 12, 2022 9:00 amWe propose an externally imposed superlattice potential as a platform for manipulating topological phases, which has both advantages and disadvantages compared to a moire superlattice. In the first example, we...

SEMINARS, OPEN NEIGHBORHOOD
October 12, 2022 4:30 pmIn 2016, Ellenberg and Gijswijt made a breakthrough on the famous cap-set problem, which asks about the maximum size of a subset of (F_3)^n not containing a three-term arithmetic progression....
