Abstract
For finite quantum systems, the boundary condition has physical as well as computational significance. Here planar spin chains are investigated with the use of a boundary condition that differs from the most commonly used periodic boundary condition. The symmetry properties then explicitly distinguish between even and odd half-integer spins. Finite-size scaling performs better with the use of this boundary.Keywords
