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…

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…

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…

Quantum subsystem codes, CFTs and their -gaugings

Keiichi Ando, Kohki Kawabata, Tatsuma Nishioka

We construct Narain conformal field theories (CFTs) from quantum subsystem codes, a more comprehensive class of quantum error-correcting codes than quantum stabilizer codes, for qu…

Entanglement Rényi entropy and boson-fermion duality in massless Thirring model

Harunobu Fujimura, Tatsuma Nishioka, Soichiro Shimamori

We investigate the second Rényi entropy of two intervals in the massless Thirring model describing a self-interacting Dirac fermion in two dimensions. Boson-fermion duality relatin…

Supersymmetric conformal field theories from quantum stabilizer codes

Kohki Kawabata, Tatsuma Nishioka, Takuya Okuda

We construct fermionic conformal field theories (CFTs) whose spectra are characterized by quantum stabilizer codes. We exploit our construction to search for fermionic CFTs with su…
