Taste-splitting mass and edge modes in D staggered fermions
Tatsuhiro Misumi, Tetsuya Onogi, Tatsuya Yamaoka
We investigate the symmetry structure of the D staggered fermion Hamiltonian and its implications for anomalies. Since the spin and flavor degrees of freedom of Dirac fermion…
The Axial Charge in Hilbert Space and the Role in Chiral Gauge Theories
Tatsuya Yamaoka
We investigate the Hamiltonian formulation of 1+1-dimensional staggered fermions and reconstruct the vector and axial charge operators, originally identified by Arkya Chatterjee et…
Non-singlet conserved charges and anomalies in 3+1 D staggered fermions
Tetsuya Onogi, Tatsuya Yamaoka
In this paper, we show that the 3+1 D staggered fermion Hamiltonian possesses, in addition to the conserved charge that generates the vector transformation,…
Quantized Axial Charge in the Hamiltonian Approach to Wilson Fermions
Tatsuya Yamaoka
We investigate the Hamiltonian formulation of 1+1~D staggered fermions and reconstruct vector and axial charge operators, found by Arkya Chatterjee et al., using the Wilson fermion…
Discrete symmetry and 't Hooft anomalies for 3450 model
Tetsuya Onogi, Hiroki Wada, Tatsuya Yamaoka
We report our study of the discrete symmetry for lattice 3450 model proposed by Wang and Wen. Lattice 3450 model is expected to describe the anomaly free chiral U(1) gauge theory i…
SU(6) model revisited
Tetsuya Onogi, Hiroki Wada, Tatsuya Yamaoka
We discuss the vacuum structure of the SU(6) model, a chiral gauge theory, from the perspective of anomaly matching. To this end, we first identify all possible 't Hooft anomalies…
