Incommensurability in the Frustrated TwoDimensional XY Model
Abstract
To examine the properties of the frustrated XY model at an incommensurate field we have examined a sequence of magnetic filling factors f which approach the irrational value of one minus the golden mean. At all f studied, the system undergoes a finitetemperature weak firstorder transition involving the freezing out of Isinglike domain walls. As one approaches incommensurability, the low temperature phase of the system changes from the staircase states found by Halsey to a striped phase consisting of a superlattice of parallel shift (Pott'slike) domain walls.
