High Chern Number Quantum Anomalous Hall States in Haldane-Graphene Multilayers

Posted by dbos This Week: Theoretical Physics, UCAS

Kavli Affiliate: Long Zhang | First 5 Authors: Yuejiu Zhao, Long Zhang, Fu-Chun Zhang, , | Summary: Quantum anomalous Hall (QAH) systems with high Chern number ($|C|>1$) are rare. This Letter introduces a Haldane-graphene multilayer heterostructure hosting QAH states with arbitrary Chern number. In a rhombohedral-stacked graphene $N$-layer, the Dirac points at $K_{pm}$ become $N^text{th}$-order […]

Emergent magnetism and spin liquids in an extended Hubbard description of moiré bilayers

Posted by dbos UCSB

Kavli Affiliate: Leon Balents | First 5 Authors: Zhenhao Song, Urban F. P. Seifert, Leon Balents, Hong-Chen Jiang, | Summary: Motivated by twisted transition metal dichalcogenides (TMDs), we study an extended Hubbard model with both on-site and off-site repulsive interactions, in which Mott insulating states with concomitant charge order occur at fractional fillings. To resolve […]

Convex Relaxation for Robust Vanishing Point Estimation in Manhattan World

Posted by dbos UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: Bangyan Liao, Zhenjun Zhao, Haoang Li, Yi Zhou, Yingping Zeng | Summary: Determining the vanishing points (VPs) in a Manhattan world, as a fundamental task in many 3D vision applications, consists of jointly inferring the line-VP association and locating each VP. Existing methods are, however, either sub-optimal […]
