The t-J model on the square lattice, close to the t-J z limit, is studied by quantum Monte Carlo techniques at finite temperature and in the underdoped regime. A variant of the Hoshen-Koppelman algorithm was implemented to identify the antiferromagnetic domains on each Trotter slice. The results show that the model at high enough temperature presents finite antiferromagnetic (AF) domains, which collapse at lower temperatures into a single ordered AF state. While there are domains, holes would…
