Description
We study the effects of non-zero isospin density on the topological susceptibility in lattice simulations with $N_f = 2 + 1$ flavors of improved staggered quarks at multiple lattice spacings. To reduce lattice artifacts, we employ a generalization of the eigenvalue reweighting technique known from vanishing densities to non-zero isospin chemical potentials, using the (massive) singular values of the Dirac operator. The results are compared with predictions from chiral perturbation theory.
