Need to print spin configuration snapshots #11

Closed shishirkrpandey closed 2 years ago

Hello Finn, May I know if it is possible to generate spin configurations snapshots at different frequency as well as for the ground state?

Thanks for your help.

Hi, The pseudofermion-FRG algorithm is formulated such that it fundamentally relies on the computation of two-spin correlations. Unfortunately, the method is therefore unable to resolve the magnetic order itself -- at least in the sense of observing finite spin expectation values associated with spontaneous symmetry breaking (see also Sec. 2.5.1 of my PhD thesis for a comment on symmetry breaking and phase transitions). It is, however, possible to resolve two-spin correlations (rather than spin configurations) and visualize them in real space, see the last example plot in the README.md. I hope this helps!
