Universal Behavior in Entanglement Entropy Reveals Quantum Criticality and Underlying Symmetry Breaking
Zhe Wang, Zehui Deng, Zenan Liu +5
Entanglement plays a key role in quantum physics, but how much information it can extract from many-body systems is still an open question, particularly regarding quantum criticali…

Surface phase transitions in a (1+1)-dimensional conformal field theory boundary coupled to a (2+1)-dimensional bulk
Zhe Wang, Shang-Qiang Ning, Zenan Liu +4
We design a (2+1))-dimensional [(2+1)D] quantum spin model in which spin-1/2 ladders are coupled through antiferromagnetic Ising interactions. The model hosts a quantum phase trans…
