Floating Phases in One-Dimensional Rydberg Ising Chains
Michael Rader, Andreas M. Läuchli
We report on the quantitative ground state phase diagram of a van der Waals interacting chain of Rydberg atoms. These systems are known to host crystalline phases locked to the und…

Finite Correlation Length Scaling in Lorentz-Invariant Gapless iPEPS Wave Functions
Michael Rader, Andreas M. Läuchli
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 ma…
