Shadow of complex fixed point: Approximate conformality of Q>4 Potts model
Han Ma, Yin-Chen He
We study the famous example of weakly first order phase transitions in the 1+1D quantum Q-state Potts model at Q>4. We numerically show that these weakly first order transitions ha…
Higher Rank Deconfined Quantum Criticality at the Lifshitz Transition and the Exciton Bose Condensate
Han Ma, Michael Pretko
Deconfined quantum critical points are characterized by the presence of an emergent gauge field and exotic fractionalized particles, which exist as well-defined excitations only at…
Fracton topological order from Higgs and partial confinement mechanisms of rank-two gauge theory
Han Ma, Michael Hermele, Xie Chen
Fractons are gapped point-like excitations in topological ordered phases whose motion is constrained. They have been discovered in several gapped models but a unifying physic…
Possible phases of the spin- model on a honeycomb lattice by boson-vortex duality
Han Ma
Motivated by recent numerical work, we use the boson-vortex duality to study the possible phases of the frustrated spin- XXZ models on the honeycomb lattice.…
