Query: LG (Landau-Ginzburg) in GL (Gregory-Laflamme)   This paper continues the study of the Gregory-Laflamme instability of black
strings, or more precisely of the order of the transition, being either first
or second order, and the critical dimension which separates the two cases.
First, we describe a novel method based on the Landau-Ginzburg perspective for
the thermodynamics that somewhat improves the existing techniques. Second, we
generalize the computation from a circle compactification to an arbitrary torus
compactifications. We explain that the critical dimension cannot be lowered in
this way, and moreover in all cases studied the transition order depends only
on the number of extended dimensions. We discuss the richer phase structure
that appears in the torus case.
