Localized RG flows on composite defects and -theorem
Dongsheng Ge, Tatsuma Nishioka, Soichiro Shimamori
We consider a composite defect system where a lower-dimensional defect (sub-defect) is embedded to a higher-dimensional one, and examine renormalization group (RG) flows localized…

Fermionic CFTs from topological boundaries in abelian Chern-Simons theories
Kohki Kawabata, Tatsuma Nishioka, Takuya Okuda +1
A quantum field theory is referred to as bosonic (non-spin) if its physical quantities are independent of the spacetime spin structure, and as fermionic (spin) if they depend on it…

Gauging symmetries of Narain CFTs
Keiichi Ando, Kohki Kawabata, Tatsuma Nishioka
We investigate the gauging of a symmetry in lattice conformal field theories (CFTs), also known as Narain CFTs. For prime , we derive a spin selection rule for op…
