Abstract
We compute numerically the zero-temperature defect energy of the vector spin glass in the limit of an infinite number of spin components , for a range of dimensions . Fitting to , where is the system size, we obtain: , , , and . These results show that the lower critical dimension (the dimension where changes sign) is significantly higher for than for finite (where ).
