Disentangling Haldane Phase by Generalized Clifford Circuits
Minsoo Kim, Changhun Oh, Donghoon Kim
Disentangling transformations play a central role in the classical simulation of quantum many-body systems, yet their analytic structure and underlying mechanism remain largely une…
Variational preparation and characterization of chiral spin liquids in quantum circuits
Zi-Yang Zhang, Donghoon Kim, Ji-Yao Chen
Quantum circuits have been shown to be a fertile ground for realizing long-range entangled phases of matter. While various quantum double models with non-chiral topological order h…
Clifford Circuits Augmented Grassmann Matrix Product States
Atis Yosprakob, Wei-Lin Tu, Tsuyoshi Okubo +2
Recent progress in combining Clifford circuits with tensor-network (TN) methods has shown that local Clifford disentanglers can reduce bipartite entanglement across TN bonds prior…
Universal Spin Screening Clouds in Local Moment Phases
Minsoo L. Kim, Jeongmin Shim, H. -S. Sim +1
When a local impurity spin interacts with conduction electrons whose density of states (DOS) has a (pseudo)gap or diverges at the Fermi energy, a local moment (LM) phase can be fav…
