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…
Fermionic and parafermionic CFTs with and symmetry
Kohki Kawabata
We investigate two-dimensional conformal field theories (CFTs) with affine and algebra symmetry. Their bosonic modular-invariant partition funct…
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…
Symmetry fractionalization and duality defects in Maxwell theory
Naoto Kan, Kohki Kawabata, Hiroki Wada
We consider Maxwell theory on a non-spin manifold. Depending on the choice of statistics for line operators, there are three non-anomalous theories and one anomalous theory with di…
Orbifolds of chiral fermionic CFTs and their duality
Kohki Kawabata, Shinichiro Yahagi
We consider chiral fermionic conformal field theories (CFTs) constructed from lattices and investigate their orbifolds under reflection and shift symmetries. For lat…
