Beyond the Flat-Band Paradigm: Open Orbits as a Route to Correlated States in Dispersive Moiré Minibands
Zihao Wang, Pablo M. Perez-Piskunow, Calvin Pei Yu Wong +16
The realization of fractional Chern insulators has largely relied on isolated flat bands in complex bilayer or multilayer moiré systems with ideal quantum geometry. Whether such ph…
Thickness-driven crossover from conventional to chiral nonreciprocal superconductivity in kagome metal CsV3Sb5
Wei Zhang, Jiangbo Luo, Nikolai Peshcherenko +10
Superconductivity and its potential applications are governed by the symmetry of the superconducting order parameter. In the kagome metal CsV3Sb5, most bulk studies indicate conven…
Giant field-tunable nonlinear Hall effect by Lorentz skew scattering in a graphene moire superlattice
Pan He, Min Zhang, Yue-Xin Huang +13
The nonlinear Hall effect (NHE) can enable rectification and energy harvesting, and its control by external fields, including gate, strain and magnetic field, has been pursued inte…
Room temperature control of axial and basal antiferromagnetic anisotropies using strain
Jack Harrison, Junxiong Hu, Charles Godfrey +6
Antiferromagnetic materials are promising platforms for the development of ultra-fast spintronics and magnonics due to their robust magnetism, high-frequency relativistic dynamics,…
Open-orbit induced low field extremely large magnetoresistance in graphene/h-BN superlattices
