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 […]
