Topological Susceptibility under Gradient Flow
Héctor Mejía-Díaz, Wolfgang Bietenholz, Krzysztof Cichy +4
We study the impact of the Gradient Flow on the topology in various models of lattice field theory. The topological susceptibility is measured directly, and by the slab…
Comparison of topological charge definitions in Lattice QCD
Constantia Alexandrou, Andreas Athenodorou, Krzysztof Cichy +5
In this paper, we show a comparison of different definitions of the topological charge on the lattice. We concentrate on one small-volume ensemble with 2 flavours of dynamical, max…
The Slab Method to Measure the Topological Susceptibility
Wolfgang Bietenholz, Krzysztof Cichy, Philippe de Forcrand +2
In simulations of a model with topological sectors, algorithms which proceed in small update steps tend to get stuck in one sector, especially on fine lattices. This distorts the n…
Computing the topological susceptibility from fixed topology QCD simulations
Arthur Dromard, Wolfgang Bietenholz, Krzysztof Cichy +1
The topological susceptibility is an important quantity in QCD, which can be computed using lattice methods. However, at a fine lattice spacing, or when using high quality chirally…
Interpreting Numerical Measurements in Fixed Topological Sectors
Wolfgang Bietenholz, Christopher Czaban, Arthur Dromard +4
For quantum field theories with topological sectors, Monte Carlo simulations on fine lattices tend to be obstructed by an extremely long auto-correlation time with respect to the t…
Combining ordinary and topological finite volume effects for fixed topology simulations
Arthur Dromard, Wolfgang Bietenholz, Urs Gerber +2
In lattice quantum field theories with topological sectors, simulations at fine lattice spacings --- with typical algorithms --- tend to freeze topologically. In such cases, specif…
