Critical phenomena in superlattices: Reentrant dimensional crossover and anomalous critical amplitudes
Lev Mikheev
A crossover from to , and then back to -dimensional critical behavior is argued to be a generic feature characterizing ordering in a -dimensional superlattice compos…

From surface to random criticality in layered planar Ising models
Lev Mikheev
A general case of a spatially nonuniform planar layered Ising model, or an equivalent quantum Ising chain, is analysed with an exact functional real space renormalization group. Va…
