Finite Correlation Length Scaling in Lorentz-Invariant Gapless iPEPS Wave Functions
It is an open question how well tensor network states in the form of an infinite projected entangled-pair states (iPEPS) tensor network can approximate gapless quantum states of matter. Here we address this issue for two different physical scenarios: (i) a conformally invariant (2+1)d quantum critic...
