Anderson duality of topological modular forms and its differential-geometric manifestations
Yuji Tachikawa, Mayuko Yamashita
We construct and study a morphism of spectra implementing the Anderson duality of topological modular forms (). Its differential version will then be introduced, allo…
Non-supersymmetric heterotic branes
Justin Kaidi, Kantaro Ohmori, Yuji Tachikawa +1
The common statement that any consistent quantum gravity theory contains dynamical objects with all possible charges suggests that there are still a number of hitherto-unidentified…
Classification of chiral fermionic CFTs of central charge
Philip Boyle Smith, Ying-Hsuan Lin, Yuji Tachikawa +1
We classify two-dimensional purely chiral conformal field theories which are defined on two-dimensional surfaces equipped with spin structure and have central charge less than or e…
Remarks on mod-2 elliptic genus
Yuji Tachikawa, Mayuko Yamashita, Kazuya Yonekura
For physicists: For supersymmetric quantum mechanics, there are cases when a mod-2 Witten index can be defined, even when a more ordinary -valued Witten index vanishes.…
On supersymmetry enhancements in three dimensions
Benjamin Assel, Yuji Tachikawa, Alessandro Tomasiello
We introduce a class of 3d theories consisting of strongly-coupled systems coupled to Chern-Simons gauge multiplets, which exhibit ${\mathcal N}=4…
Asymptotic density of states in 2d CFTs with non-invertible symmetries
Ying-Hsuan Lin, Masaki Okada, Sahand Seifnashri +1
It is known that the asymptotic density of states of a 2d CFT in an irreducible representation of a finite symmetry group is proportional to . We show how this s…
