For the cases in which the two vertical sides of the rectangle have up-spin boundary conditions + and the two horizontal sides with either down-spin boundary conditions − or with free-spin boundary conditions f, exact results are presented for the density profiles of the energy and the order parameter which display a surprisingly rich behavior. The new results follow by means of conformal transformations from known results in the half plane with +−+−+ and +f+f+ boundary conditions. The corners with mixed boundary conditions lead to interesting behavior, even in the limit of a half-infinite strip. The behavior near these corners can be described by a “corner-operator-expansion,” which is discussed in the second part of the paper. The analytic predictions agree very well with simulations, with no adjustable parameters.}, cin = {IBI-5 / IAS-2}, ddc = {530}, cid = {I:(DE-Juel1)IBI-5-20200312 / I:(DE-Juel1)IAS-2-20090406}, pnm = {5243 - Information Processing in Distributed Systems (POF4-524)}, pid = {G:(DE-HGF)POF4-5243}, typ = {PUB:(DE-HGF)16}, pubmed = {37978636}, UT = {WOS:001095367500003}, doi = {10.1103/PhysRevE.108.044133}, url = {https://juser.fz-juelich.de/record/1017346}, }
