Engineering topological flat bands in -valley moiré systems with Ising-type SOC: twisted 1T-ZrS and 1T-SnSe
Hanqi Pi, Yves H. Kwan, Haoyu Hu +8
Twisted moiré superlattices hosting topological flat bands provide a platform to explore the interplay between topology and correlations. Here we investigate topological band stru…
Superconductivity and Ferroelectric Orbital Magnetism in Semimetallic Rhombohedral Hexalayer Graphene
Jinghao Deng, Jiabin Xie, Hongyuan Li +5
Rhombohedral multilayer graphene has emerged as a promising platform for exploring correlated and topological quantum phases, enabled by its Berry-curvature-bearing flat bands. Whi…
Emergence of a symmetry-broken Chern insulator near a moiré Kondo breakdown
Wanghao Tian, Bowen Shen, Lizhong Li +14
Moiré semiconductors built on angle-aligned transition metal dichalcogenide (TMD) heterobilayers provide a physical realization of the Kondo lattice model, in which one TMD layer…
Electric-field-tuned consecutive topological phase transitions between distinct correlated insulators in moire MoTe2/WSe2 heterobilayer
Xumin Chang, Zui Tao, Bowen Shen +10
Consecutive topological phase transitions (TPTs) between strongly correlated electronic phases that differ simultaneously in symmetry breaking and topological order are of fundamen…
Mechanical sensing of metamagnetic tricriticality in two-dimensional CrI3
Feng Liu, Jiayong Xiao, Shengwei Jiang +2
Layered Ising metamagnets are antiferromagnetic (AF) materials consisting of monolayer Ising ferromagnets coupled to each other via interlayer AF interactions. They exhibit rich ma…
Imaging propagating terahertz collective modes in two-dimensional semiconductor double layers
Andrew T. Pierce, Chirag Vaswani, Dimitri Pimenov +7
Two-dimensional transition metal dichalcogenide (TMD) semiconductors exhibit a wide range of novel phenomena at millielectronvolt (terahertz-frequency) energy scales, including sup…
