The Deconfined Phase Transition under the Fuzzy Sphere Microscope: Approximate Conformal Symmetry, Pseudo-Criticality, and Operator Spectrum
Zheng Zhou, Liangdong Hu, W. Zhu +1
The deconfined quantum critical point (DQCP) is an example of phase transitions beyond the Landau symmetry breaking paradigm that attracts wide interest. However, its nature has no…
Phase diagrams of spin- Kitaev ladders
Yushao Chen, Yin-Chen He, Aaron Szasz
We investigate the ground states of spin- Kitaev ladders using exact analytical solutions (for ), perturbation theory, and the density matrix renormalization group (DMR…
Phase diagram of a bilinear-biquadratic spin-1 model on the triangular lattice from density matrix renormalization group simulations
Aaron Szasz, Chong Wang, Yin-Chen He
We investigate a highly frustrated spin-1 model on the triangular lattice, with nearest- and next-nearest-neighbor antiferromagnetic interactions and nearest-neighbor $(…
Topological characterization of Lieb-Schultz-Mattis constraints and applications to symmetry-enriched quantum criticality
Weicheng Ye, Meng Guo, Yin-Chen He +2
Lieb-Schultz-Mattis (LSM) theorems provide powerful constraints on the emergibility problem, i.e. whether a quantum phase or phase transition can emerge in a many-body system. We d…
Conformal bootstrap bounds for the Dirac spin liquid and Stiefel liquid
Yin-Chen He, Junchen Rong, Ning Su
We apply the conformal bootstrap technique to study the Dirac spin liquid (i.e. QED) and the newly proposed Stiefel liquid (i.e. a conjectured 3d non-Lagra…
Stiefel Liquids: Possible Non-Lagrangian Quantum Criticality from Intertwined Orders
Liujun Zou, Yin-Chen He, Chong Wang
We propose a new type of quantum liquids, dubbed Stiefel liquids, based on dimensional nonlinear sigma models on target space , supplemented with Wess-Zumino-Wit…
