Computing the topological susceptibility from fixed topology QCD simulations
TL;DR: In this paper, the authors explore two methods to extract the topological susceptibility from lattice QCD simulations restricted to a single topological sector, based on the correlation function of the topology charge density, while the second method relies on measuring the topologically charge within spacetime subvolumes.

TL;DR: In this article, a method of tuning the quark masses to their physical values is discussed, where the singlet quark mass is kept fixed, which solves the problem of different renormalisations occuring for non-chirally invariant lattice fermions.

TL;DR: In this article, a set of Wilson coefficients is evaluated on a 24 3 × 48 lattice with overlap quarks, and results for the leading Wilson coefficients are extracted by means of Singular Value Decomposition.

New insight into the Berezinskii-Kosterlitz-Thouless phase transition
TL;DR: In this paper, the authors investigated the 2D XY model by using the constraint angle action, which belongs to the class of topological lattice actions and shows excellent scaling behavior.

A non-perturbative study of non-commutative U(1) gauge theory )
TL;DR: In this paper, Monte Carlo simulations are performed after mapping the regularized theory onto a U(N) lattice gauge theory in d = 2, where the dispersion relation involves a negative IR-singular term.
