Title: High-throughput calculations of topological and nodal 
superconductivity in materials
Date/Time: 16:30-18:00, Friday, October 21, 2022 (Please note that the time 
slot is 30 minute later than usual.)
Abstract: Symmetry-transformation properties of Cooper pairs under spatial 
symmetries, dubbed pairing symmetry, are closely related to how electrons 
pair up. However, pairing symmetries for the majority of materials are not 
known. Sidestepping this issue, we tackle an alternative problem: we 
predict topological and nodal superconductivity in materials for each 
possible pairing symmetry. Our results could be compared with experimental 
results and reduce the candidates of pairing symmetries. In this talk, 
after reviewing our diagnostic scheme, we apply our method to some recently 
discovered superconductors.
This talk is based on the following paper: Feng Tang*, Seishiro Ono*, 
Xiangang Wan, and Haruki Watanabe, Phys. Rev. Lett. 129, 027001 (2022).

Title: Structures and functions of chemical reaction networks
Date/Time: 16:00-17:30, Friday, November 25, 2022
Abstract: Chemical reactions form a large web of networks inside living 
cells and they are responsible for physiological functions. Understanding 
the behavior of complex reaction networks is a challenging and interesting 
problem. In this talk, I would like to illustrate how the techniques used 
in algebraic topology can shed light on the relationship between structures 
and functions of chemical reaction systems. In particular, we will discuss 
the following two problems: (1) response of reaction systems to external 
perturbations and (2) simplification of complex reaction networks without 
altering the behavior of the system.
