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…
Higher-Winding Fractionalization
Kishore Iyer, Christophe Mora, Daniele Guerci
Higher-winding skyrmion textures can generate emergent magnetic fields with multiple flux quanta per unit cell. This opens an intriguing route toward fractionalization, allowing fr…
