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…
Lifshitz transitions and isospin polarization in twist-decoupled monolayer-bilayer graphene
Alex Boschi, Leonardo Sabattini, Sergey Slizovskiy +11
Bernal-stacked bilayer graphene (BLG) hosts correlated electronic phases tied to low-energy Lifshitz transitions at saddle points in its valence band. To access this regime, ultral…
Anomalous metal and superconducting phases in rhombohedral graphene
Anna Okounkova, Abigail Sohm, Tobias Faehndrich +7
The paper investigates gate‑tuned regions in rhombohedral graphene on a WSe₂ substrate that show either zero‑resistance superconductivity or a finite‑resistance “anomalous metal” s…
Quantum oscillation spectroscopy of Fermi-surface topologies in tetralayer graphene
Abhijit Halder, Harsh Varshney, Snehamoyee Hazra +7
Quantum oscillations offer a direct probe of Fermi-surface topology and electronic degeneracy, yet disentangling both simultaneously across the Lifshitz transitions of multiband sy…
Van Hove singularity-driven giant Nernst signal in twisted double bilayer graphene
Ujjal Roy, Monosij Roy, Unmesh Ghorai +8
Twisted graphene layers host van Hove singularities (vHSs), peaks in the electronic density of states, thought to drive exotic phases in moiré materials, but their effect on therm…
Multi-Knob Switchable Chiral Superconductivity Quartet in Rhombohedral Graphene
Zhenqi Hua, Shenyong Ye, Phatthanon Pattanakanvijit +17
Chiral superconductors break orbital time-reversal symmetry and may host topological quasiparticles with non-Abelian statistics. In rhombohedral graphene, superconductivity develop…
