Interlayer Exciton Condensate Stiffness Is Non-Monotonic in Quantum Metric
Bo Zou, Yitong Zhang, Siddhartha Sarkar +3
Identifying the origin of the superfluid stiffness of electron-electron and electron-hole pair condensates is an important issue in flat-band physics. Here, we study the stiffness…
How Similar Can Fractional Chern Insulators Be to Fractional Quantum Hall States? Moiré-Enhanced Gaps and Excitation-Spectrum Correspondence
Siddhartha Sarkar, Yitong Zhang, Kai Sun
Fractional Chern insulators (FCIs) realize fractional quantum Hall topology in lattice bands, but their excitation spectra remain far less understood than their ground states. Here…
Beyond the Lowest Landau Level: Unlocking More Robust Fractional States Using Flat Chern Bands with Higher Vortexability
Yitong Zhang, Siddhartha Sarkar, Xiaohan Wan +3
Enhancing the many-body gap of a fractional state is crucial for realizing robust fractional excitations. For fractional Chern insulators, existing studies suggest that making flat…
Ideal topological flat bands in chiral symmetric moiré systems from non-holomorphic functions
Siddhartha Sarkar, Xiaohan Wan, Yitong Zhang +1
Recent studies on topological flat bands and their fractional states have revealed increasing similarities between moiré flat bands and Landau levels (LLs). For instance, like the…
