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 […]
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 […]
Kavli Affiliate: Shenghan Jiang | First 5 Authors: Brenden Roberts, Shenghan Jiang, Olexei I. Motrunich, , | Summary: We continue recent efforts to discover examples of deconfined quantum criticality in one-dimensional models. In this work we investigate the transition between a $mathbb{Z}_3$ ferromagnet and a phase with valence bond solid (VBS) order in a spin […]

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) […]
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 […]
Kavli Affiliate: Biao Huang | First 5 Authors: Xunyuan Yin, Song Bo, Jinfeng Liu, Biao Huang, | Summary: The development of advanced closed-loop irrigation systems requires accurate soil moisture information. In this work, we address the problem of soil moisture estimation for the agro-hydrological systems in a robust and reliable manner. A nonlinear state-space model […]
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 […]
Kavli Affiliate: Fuchun Zhang | First 5 Authors: Yi Zhang, Kun Jiang, Fuchun Zhang, Jian Wang, Ziqiang Wang | Summary: Topological superconductors (TSCs) are correlated quantum states with simultaneous off-diagonal long-range order and nontrivial topological invariants. They produce gapless or zero energy boundary excitations, including Majorana zero modes and chiral Majorana edge states with topologically […]
Kavli Affiliate: Xinan Zhou | First 5 Authors: Nadav Drukker, Simone Giombi, Arkady A. Tseytlin, Xinan Zhou, | Summary: Surface operators in the 6d (2,0) theory at large $N$ have a holographic description in terms of M2 branes probing the AdS$_7 times S^4$ M-theory background. The most symmetric, 1/2-BPS, operator is defined over a planar […]
