Collision-Hull Compression for Homogeneous Keller Maps and a Forty-Variable Counterexample to Zhao's Vanishing Conjecture
Thomas Prellberg
We formulate an elementary collision-generated compression principle for homogeneous Keller maps. In the language of polarization algebras, the construction takes the subalgebra ge…
Four-moment criteria for Poisson convergence on Poisson and Rademacher chaoses
Guangqu Zheng
In this paper, we establish Poisson limit theorems on Poisson and Rademacher chaoses. Our principal result is a total-variation bound, valid in both settings, for an integer-valued…
Fermiology and the Candidate Chiral Superconductor in Rhombohedral Tetralayer Graphene
Sandesh S. Kalantre, Ben H. Alexander, Julian May-Mann +11
Chiral superconductivity, in which the phase of the superconducting order parameter winds in momentum space, has long been sought for its close link to topological superconductivit…
Interplay between many-body correlations, strain and lattice relaxation in twisted bilayer graphene
Lorenzo Crippa, Gautam Rai, Dumitru CÄlugÄru +6
In twisted bilayer graphene, a unified understanding of the mechanisms governing temperature-dependent electronic spectra and thermodynamic properties remains controversial despite…
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…
Exact models of chiral flat-band superconductors
Zhaoyu Han, Jonah Herzog-Arbeitman, Qiang Gao +1
Recent experiments have reported the surprising observation of superconductivity in flavor polarized, nearly flat bands (FBs) of rhombohedral graphene. Motivated by these findings,…
