Manifold tensor categories
Christoph Weis
We introduce Manifold tensor categories, which make precise the notion of a tensor category with a manifold of simple objects. A basic example is the category of vector spaces grad…
The Drinfel'd centres of String 2-groups
Christoph Weis
Let be a compact connected Lie group and a cohomology class. The String 2-group is the central extension of by the 2-group cl…
Constructing the Virasoro groups using differential cohomology
Arun Debray, Yu Leon Liu, Christoph Weis
The Virasoro groups are a family of central extensions of , the group of orientation-preserving diffeomorphisms of , by the circle group . We…
Simulation strategies for the massless lattice Schwinger model in the dual formulation
Daniel Göschl, Christof Gattringer, Alexander Lehmann +1
The dual form of the massless Schwinger model on the lattice overcomes the complex action problems from two sources: a topological term, as well as non-zero chemical potential, mak…
