Topological Susceptibility of the 2d O(3) Model under Gradient Flow / Bietenholz, Wolfgang (UNAM, Mexico ; U. Bern, AEC) ; de Forcrand, Philippe (Zurich, ETH) ; Gerber, Urs (U. Bern, AEC) ; Mejía-Díaz, Héctor (UNAM, Mexico) ; Sandoval, Ilya O. (UNAM, Mexico)
The 2d O(3) model is widely used as a toy model for ferromagnetism and for Quantum Chromodynamics. With the latter it shares --- among other basic aspects --- the property that the continuum functional integral splits into topological sectors. [...]

Topological Susceptibility under Gradient Flow / Mejía-Díaz, Héctor (Mexico U., ICN) ; Bietenholz, Wolfgang (Mexico U., ICN) ; Cichy, Krzysztof (Frankfurt U. ; Mickiewicz U., Poznan) ; de Forcrand, Philippe (CERN ; Zurich, ETH) ; Dromard, Arthur (Regensburg U.) ; Gerber, Urs (IFM-UMSNH, Michoacan ; Mexico U., ICN) ; Sandoval, Ilya Orson (Mexico U., ICN)
We study the impact of the Gradient Flow on the topology in various models of lattice field theory. The topological susceptibility $\chi_{\rm t}$ is measured directly, and by the slab method, which is based on the topological content of sub-volumes ("slabs") and estimates $\chi_{\rm t}$ even when the system remains trapped in a fixed topological sector.

Topology in the 2d Heisenberg Model under Gradient Flow / Sandoval, Ilya O. (Mexico U., ICN) ; Bietenholz, Wolfgang (Mexico U., ICN) ; de Forcrand, Philippe (CERN ; Zurich, ETH) ; Gerber, Urs (IFM-UMSNH, Michoacan ; Mexico U., ICN) ; Mejía-Díaz, Héctor (Mexico U., ICN)
The 2d Heisenberg model --- or 2d O(3) model --- is popular in condensed matter physics, and in particle physics as a toy model for QCD. Along with other analogies, it shares with 4d Yang-Mills theories, and with QCD, the property that the configurations are divided in topological sectors. [...]
