Tuning spin-density separation via finite-range interactions: Dimensionality-driven signatures in dynamic structure factors
Xiaoran Ye, Yi Zhang, Ziheng Zhou +1
Spin-density (charge) separation, marked by distinct propagation velocities of spin and density excitations, epitomizes strong correlations, historically confined to one-dimensiona…

(1,0,0)-colorability of planar graphs without cycles of length 4 or 6
Ligang Jin, Yingli Kang, Peipei Liu +1
A graph is -colorable if the vertex set can be partitioned into three subsets and such that for , the induced graph $G[V_i]…

Partially normal 5-edge-colorings of cubic graphs
Ligang Jin, Yingli Kang
In a proper edge-coloring of a cubic graph, an edge is normal if the set of colors used by the edges adjacent to has cardinality 3 or 5. The Petersen coloring conjecture as…
