Majorana zero modes in the Kitaev chain protect boundary quantum Fisher information from delocalization, maintaining a nonzero plateau for exponentially long times.
Rounded hard squares confined in a circle transition from a cross-shaped tetratic domain with four +1/4 disclinations to a six-domain partition with six +1/4 disclinations and one central -1/2 disclination as roundness increases.
