Multiversality and unnecessary criticallity in one dimension
We present microscopic models of spin ladders which exhibit continuous critical surfaces whose properties and existence, unusually, cannot be inferred from those of the flanking phases. These models exhibit either “multiversality”—the presence of different universality classes over finite regions of...
