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: 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: 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 […]
