Counterexamples to a conjecture and improved bounds for bipanchromatic colorings
Stefan Novaković, Duško Jojić
We study the bipanchromatic number , introduced by Lalou et al. (Discrete Appl. Math. 391 (2026), 511-522) as the maximum number of colors in a panchromatic hypergraph colorin…
Nontrivial Boundary-Mediated Superconducting Transport in a TRSB Topological Iron-Based Superconductor
Wenyao Liu, Gabriel Natale, Camron Farhang +22
The interplay of superconductivity, band topology, and spontaneous time-reversal-symmetry breaking (TRSB) is expected to enable topological superconducting boundary states. FeTe0.5…
Quantum Geometry Induced Kekulé Superconductivity in Haldane phases
Yafis Barlas, Fan Zhang, Enrico Rossi
Chiral two-dimensional electron gases, which capture the electronic properties of graphene and rhombohedral graphene systems, exhibit singular momentum-space vortices and are susce…
Weyl-Superconductivity revealed by Edge Mode mediated Nonlocal Transport
Wenyao Liu, Gabriel Natale, Camron Farhang +24
Topological superconductivity (TSC) hosts exotic modes enabling error-free quantum computation and low-temperature spintronics. Despite preliminary evidence of edge modes, unambigu…
