Floquet chiral hinge modes and their interplay with Weyl physics in a three-dimensional lattice

Kavli Affiliate: Biao Huang | First 5 Authors: Biao Huang, Viktor Novičenko, André Eckardt, Gediminas Juzeliūnas, | Summary: We demonstrate that a three dimensional time-periodically driven (Floquet) lattice can exhibit chiral hinge states and describe their interplay with Weyl physics. A peculiar type of the hinge states are enforced by the repeated boundary reflections with […]

Local Operator Entanglement in Spin Chains

Kavli Affiliate: Masahiro Nozaki | First 5 Authors: Eric Mascot, Masahiro Nozaki, Masaki Tezuka, , | Summary: Understanding how and whether local perturbations can affect the entire quantum system is a fundamental step in understanding non-equilibrium phenomena such as thermalization. This knowledge of non-equilibrium phenomena is applicable for quantum computation, as many quantum computers employ […]

XraySyn: Realistic View Synthesis From a Single Radiograph Through CT Priors

Kavli Affiliate: Cheng Peng | First 5 Authors: Cheng Peng, Haofu Liao, Gina Wong, Jiebo Luo, Shaohua Kevin Zhou | Summary: A radiograph visualizes the internal anatomy of a patient through the use of X-ray, which projects 3D information onto a 2D plane. Hence, radiograph analysis naturally requires physicians to relate the prior about 3D […]

P-orbital magnetic topological states on square lattice

Kavli Affiliate: Bo Gu | First 5 Authors: Jing-Yang You, Bo Gu, Gang Su, , | Summary: Honeycomb or triangular lattices were extensively studied and thought to be proper platforms for realizing quantum anomalous Hall effect (QAHE), where magnetism is usually caused by d orbitals of transition metals. Here we propose that square lattice can […]

Doped Mott Insulators in the Triangular Lattice Hubbard Model

Kavli Affiliate: Zheng Zhu | First 5 Authors: Zheng Zhu, D. N. Sheng, Ashvin Vishwanath, , | Summary: We investigate the evolution of the Mott insulators in the triangular lattice Hubbard Model, as a function of hole doping $delta$ in both the strong and intermediate coupling limits. Using the advanced density matrix renormalization group (DMRG) […]

Enhanced corrections near holographic entanglement transitions: a chaotic case study

Kavli Affiliate: Huajia Wang | First 5 Authors: Xi Dong, Huajia Wang, , , | Summary: Recent work found an enhanced correction to the entanglement entropy of a subsystem in a chaotic energy eigenstate. The enhanced correction appears near a phase transition in the entanglement entropy that happens when the subsystem size is half of […]

Entanglement of Local Operators and the Butterfly Effect

Kavli Affiliate: Masahiro Nozaki | First 5 Authors: Jonah Kudler-Flam, Masahiro Nozaki, Shinsei Ryu, Mao Tian Tan, | Summary: We study the robustness of quantum and classical information to perturbations implemented by local operator insertions. We do this by computing multipartite entanglement measures in the Hilbert space of local operators in the Heisenberg picture. The […]
