Critical exponents of the U(n) vector spin glasses

The critical exponents of the classical spin glasses with
symmetry are obtained to order 
of
the ϵ-expansion around six dimensions, where 
.
This new unitary symmetry is realized in the
m-vector (
)
spin glasses with
anisotropic quenched random Dzyaloshinskii-Moriya (DM)
interaction. Such a random DM interaction with n
correlated couplings
leads to critical exponents which
are different from those of any isotropic m-vector spin glass
and thus belong to
new universality classes.
