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…
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…
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…
Electrical control of a Kondo spin screening cloud
Ngoc Han Tu, Donghoon Kim, Minsoo L. Kim +8
Quantitative analysis of quantum many-body systems, consisting of numerous itinerant electrons that interact with localized spins or electrons, is a long-standing issue. The Kondo…
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…
