Speaker: Boris Kjær (​University of Copenhagen).Abstract:In recent years, the analysis of topologically ordered ground states of 2d quantum lattice systems in the thermodynamic limit has been developed to provide a rigorous invariant of gapped phases. The methodology is based on the approach of Doplicher, Haag, and Roberts in the context of algebraic quantum field theory, and derives a braided C*-tensor category which represents the anyonic excitations above the ground state and the fusion and braiding among them. We present the computation of this category for the class of Levin-Wen models, which yields the Drinfeld center Z(C) of an arbitrary unitary fusion category C up to braided monoidal equivalence. Previous methods, applied to quantum double models based on finite groups, relied on defining string operators on the quasi-local observable algebra implementing an action of Z(Vec_G). But there are obstructions in K-theory that limit this approach to group-like models with integer quantum dimensions. Our approach requires detailed understanding of the local ground state spaces of the model in terms of topological quantum field theory based on skein modules. Based on work joint with Alex Bols.

SDU and NAFA invite you to a webinar where PhD Sizwe Nxasana presents his research on how to support teachers in unlearning old habits and adopting new, more student-centered teaching methods – and on identifying which forms of professional development actually work to make this happen. This presentation offers a unique insight into how project-based learning (PBL) is being adopted and developed in a South African context.At NiSE webinars, Danish science education researchers meet to further develop the science education knowledge ecology.It is about ensuring that everyone both receives knowledge and contributes knowledge and experiences within the pedagogical and scientific work of science education.The NiSE webinars are organized by the STEM Education Research Center – FNUG and the Center of Excellence in Science Education/Naturfagsakademiet (CESE/NAFA). NiSE is the name of the network: Network in STEM Education.This webinar is the second in a series of three during the autumn semester of 2025.Everyone is welcome.
