Robustness of critical U(1) spin liquids and emergent symmetries in tensor networks
Henrik Dreyer, Laurens Vanderstraeten, Ji-Yao Chen +2
We study the response of critical Resonating Valence Bond (RVB) spin liquids to doping with longer-range singlets, and more generally of U(1)-symmetric tensor networks to non-symme…

SU Chiral Spin Liquid on the Square Lattice: a View from Symmetric PEPS
Ji-Yao Chen, Sylvain Capponi, Alexander Wietek +3
Quantum spin liquids can be faithfully represented and efficiently characterized within the framework of Projected Entangled Pair States (PEPS). Guided by extensive exact diagonali…
