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…
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…
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…
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…
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…
Elliptic genera from classical error-correcting codes
Kohki Kawabata, Shinichiro Yahagi
We consider chiral fermionic conformal field theories constructed from classical error-correcting codes and provide a systematic way of computing their elliptic genera. We exploit…
Narain CFTs from quantum codes and their gauging
Kohki Kawabata, Tatsuma Nishioka, Takuya Okuda
We investigate the gauging of a symmetry in Narain conformal field theories (CFTs) constructed from qudit stabilizer codes. Considering both orbifold and fermionizat…
Narain CFTs from nonbinary stabilizer codes
Yasin Ferdous Alam, Kohki Kawabata, Tatsuma Nishioka +2
We generalize the construction of Narain conformal field theories (CFTs) from qudit stabilizer codes to the construction from quantum stabilizer codes over the finite field of prim…
Fermionic CFTs from classical codes over finite fields
Kohki Kawabata, Shinichiro Yahagi
We construct a class of chiral fermionic CFTs from classical codes over finite fields whose order is a prime number. We exploit the relationship between classical codes and Euclide…
Narain CFTs from qudit stabilizer codes
Kohki Kawabata, Tatsuma Nishioka, Takuya Okuda
We construct a discrete subset of Narain CFTs from quantum stabilizer codes with qudit (including qubit) systems whose dimension is a prime number. Our construction exploits three…
Replica wormholes and capacity of entanglement
Kohki Kawabata, Tatsuma Nishioka, Yoshitaka Okuyama +1
We consider the capacity of entanglement as a probe of the Hawking radiation in a two-dimensional dilaton gravity coupled with conformal matter of large degrees of freedom. A formu…
Probing Hawking radiation through capacity of entanglement
Kohki Kawabata, Tatsuma Nishioka, Yoshitaka Okuyama +1
We consider the capacity of entanglement in models related with the gravitational phase transitions. The capacity is labeled by the replica parameter which plays a similar role to…
