Tangent fermions can restore vacuum stability of discrete-time Dirac models
C. W. J. Beenakker
The Dirac quantum walk (a 1+1 dimensional space-time discretization of the Dirac equation) has a mass gap both at the center and at the corner of the quasi-energy-momentum Bri…

Quantum circuit decomposition of the tangent-fermion Dirac operator
C. W. J. Beenakker
The Dirac operator on a lattice cannot be both local and free of fermion doubling, at least not without breaking fundamental symmetries. Non-local, symmetry-preserving discretizati…

Symmetric mass generation of interacting chiral fermions on a one-dimensional lattice without fermion doubling
V. A. Zakharov, Atsushi Ueda, Frank Verstraete +1
Symmetric mass generation is the interaction-induced opening of a fermion gap without spontaneous symmetry breaking. The anomaly-free 3-4-5-0 model of Wang and Wen provides a minim…
