Recycled Gas Dominates the Metal-rich Fuel of Supermassive Black Holes
Dongyun Kwak, Ena Choi, Hannah Jhee +5
Understanding the origin and chemical properties of gas accreted by supermassive black holes (SMBHs) is essential for linking black hole growth to galaxy evolution. Using a suite o…
Magnetic-Field-Driven Insulator-Superconductor Transition in Rhombohedral Graphene
Jian Xie, Zihao Huo, Zhimou Chen +5
Recent studies of rhombohedral multilayer graphene (RMG) have revealed a variety of superconducting states that can be induced or enhanced by magnetic fields, reinforcing RMG as a…
Does Moire Matter? Critical Moire Dependence with Quantum Fluctuations in Graphene Based Integer and Fractional Chern Insulators
Zihao Huo, Wenxuan Wang, Jian Xie +11
Rhombohedral multilayer graphene has emerged as a powerful platform for investigating flat-band-driven correlated phenomena, yet most aspects remain not understood. In this work, w…
Unconventional Orbital Magnetism in Graphene-based Fractional Chern Insulators
Jian Xie, Zaizhe Zhang, Xi Chen +11
Orbital magnetism in graphene originates from correlation-driven spontaneous valley symmetry breaking1-7. It can lead to various anomalous transport phenomena such as integer and f…
Tunable Fractional Chern Insulators in Rhombohedral Graphene Superlattices
Jian Xie, Zihao Huo, Xin Lu +11
Fractional Chern insulators (FCIs) showing a transport effect with fractionally quantized Hall plateaus emerging under zero magnetic field, provide a radically new opportunity to e…
