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…
Proposal for the Quantum Simulation of the CP(2) Model on Optical Lattices
Catherine Laflamme, Wynne Evans, Marcello Dalmonte +5
The 2d CP(N-1) models share a number of features with QCD, like asymptotic freedom, a dynamically generated mass gap and topological sectors. They have been formulated and analysed…
Simulations at fixed topology: fixed topology versus ordinary finite volume corrections
Arthur Dromard, Wolfgang Bietenholz, Urs Gerber +2
Lattice QCD simulations tend to get stuck in a single topological sector at fine lattice spacing, or when using chirally symmetric quarks. In such cases computed observables differ…
Measuring the Topological Susceptibility in a Fixed Sector
Irais Bautista, Wolfgang Bietenholz, Arthur Dromard +5
For field theories with a topological charge Q, it is often of interest to measure the topological susceptibility chi_t = ( < Q^2 > - < Q >^2 ) / V. If we manage to perform a Monte…
