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…
Continuous correlated states and dual-flatness in a moiré heterostructure
Mohammed M. Al Ezzi, Na Xin, Yanmeng Shi +13
Many-body effects in condensed matter yield novel quantum states when the electronic density of states is enhanced. A vivid example is flat bands, which suppress kinetic energy and…
On the Fundamental Resource for Exponential Advantage in Quantum Channel Learning
Minsoo Kim, Changhun Oh
Quantum resources enable us to achieve an exponential advantage in learning the properties of unknown physical systems by employing quantum memory. While entanglement with quantum…
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…
Multiphase superconductivity in PdBi2
Lewis Powell, Wenjun Kuang, Gabriel Hawkins-Pottier +13
Unconventional superconductivity, where electron pairing does not involve electron-phonon interactions, is often attributed to magnetic correlations in a material. Well known examp…
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…
