Lattice regularizations of θ vacua: anomalies and qubit models

HIGHLIGHTS

• who: Mendel Nguyen from the DepartmentState University, Raleigh, North Carolina, USA have published the research work: Lattice regularizations of u03b8 vacua: Anomalies and qubit models, in the Journal: (JOURNAL) of 11/01/2023
• what: Using the Grassmannian NLu03c3Ms as a case study the authors provide examples of lattice regularizations in which both possibilities are realized. The authors show that perhaps surprisingly the conventional lattice regularization of u03b8 vacua due to Berg and Lu00fcscher reproduces the anomaly exactly on the lattice providing a realization of the second possibility. The authors take a step back and attempt . . .
