CREST Research Seminar on "Theoretical studies of topological phases of matter"

We have an online seminar on "Theoretical studies of topological phases of matter", which is a research subject in the CREST program "Creation of Core Technology based on the Topological Materials Science for Innovative Devices" of Japan Science and Technology Agency. This is supported by the CREST Grant (Number: JPMJCR19T2) held by Yasuyuki Kawahigashi (the University of Tokyo) together with Akira Furusaki (RIKEN) and Masatoshi Sato (Yukawa Institute for Theoretical Physics, Kyoto University). The aim of this seminar is to foster interactions between mathematicians and physicists and promote joint research among the CREST group members. We plan to have one talk every month approximately.

• Speaker: Philip Boyle Smith (Kavli IPMU)
• Title: Duality webs of chiral fermionic CFTs with c ≤ 16
• Date/Time: 17:00-18:30, Friday, December 22, 2023 (Note that the time slot is different from the usual one.)
• Abstract: We classified all chiral fermionic CFTs of central charge ≤ 16 using Kac's theorem and bosonisation. This talk will discuss the derivation of this result, its application to non-supersymmetric heterotic strings, and how such theories fall into duality webs under topological manipulations involving the spin structure. The latter part will involve addressing some often-overlooked subtleties of bosonisation in gravitationally-anomalous theories, which we do from various perspectives involving anomalies, topological phases, and TFTs.

Registration

The talk will be online with Zoom. The Zoom link will be sent by e-mail to those who have registered on the above form. If you have any inquiry, please contact Kawahigashi (yasuyuki@ms.u-tokyo.ac.jp).
