March 24, 2022 9:30 amI will talk about the edge physics of the deconfined quantum phase transition (DQCP) between a spontaneous quantum spin Hall (QSH) insulator and a spin-singlet superconductor (SC). Although the bulk...

March 24, 2022 9:00 amThe operadic structure on the moduli spaces of algebraic curves encodes in a combinatorial way how nodal curves in the boundary can be obtained by glueing smooth curves along marked...

March 24, 2022 1:00 pmThe developmental cycle of Myxococcus xanthus involves the coordination of many hundreds of thousands of cells aggregating to form mounds known as fruiting bodies. This aggregation process begins with the sequential formation...

March 23, 2022 9:30 amOver the last century, ecologists, statisticians, physicists, financial quants, and other scientists discovered that, in many examples, the sample variance approximates a power of the sample mean of each of...

SEMINARS, OPEN NEIGHBORHOOD
March 23, 2022 4:30 pmThese are three concepts that examine how quantities vary: invariance and equivariance, from mathematics, and covariance, from statistics. How do they relate to each other? We will see how groups...

March 23, 2022 3:00 pmCohen and Lenstra gave a conjectural distribution for the class group of a random quadratic number field. Since the class group is the Galois group of the maximum abelian unramified...

CMSA GENERAL RELATIVITY SEMINAR, SEMINARS
March 23, 2022 2:00 pmWe explore the use of expert iteration in the context of language modeling applied to formal mathematics. We show that at same compute budget, expert iteration, by which we mean...

March 23, 2022 10:30 amI will show that a quantum state in a lattice spin (boson) system must be long-range entangled if it has non-zero lattice momentum, i.e. if it is an eigenstate of...

March 22, 2022 9:30 amWe introduce a class of random graph processes, which we call \emph{flip processes}. Each such process is given by a \emph{rule} which is just a function $\mathcal{R}:\mathcal{H}_k\rightarrow \mathcal{H}_k$ from all...
