# Zero-temperature phase of the XY spin glass in two dimensions: Genetic embedded matching heuristic

@article{Weigel2008ZerotemperaturePO, title={Zero-temperature phase of the XY spin glass in two dimensions: Genetic embedded matching heuristic}, author={Martin Weigel and Michel J. P. Gingras}, journal={Physical Review B}, year={2008}, volume={77}, pages={104437} }

For many real spin-glass materials, the Edwards-Anderson model with continuous-symmetry spins is more realistic than the rather better understood Ising variant. In principle, the nature of an occurring spin-glass phase in such systems might be inferred from an analysis of the zero-temperature properties. Unfortunately, with few exceptions, the problem of finding ground-state configurations is a non-polynomial problem computationally, such that efficient approximation algorithms are called for…
