Ultrafast signatures of spin and orbital order in antiferromagnetic α-Sr2CrO4
Communications Physics, 2022 Strongly correlated electron systems, such as the chromates, can exhibit a range of unique electronic configurations, the phase diagram of which can become even richer when considering non-equilibrium properties. Here, the authors apply ultrafast optical

Chromatic Bounds on Orbital Chromatic Roots [PDF]
The Electronic Journal of Combinatorics, 2014 Given a group $G$ of automorphisms of a graph $\Gamma$, the orbital chromatic polynomial $OP_{\Gamma,G}(x)$ is the polynomial whose value at a positive integer $k$ is the number of orbits of $G$ on proper $k$-colorings of $\Gamma.$ Cameron and Kayibi introduced this polynomial as a means of understanding roots of chromatic polynomials.

Journal of Combinatorial Theory, Series A, 2021 In 1995 Stanley introduced the chromatic symmetric function $X_G$ of a graph $G$, whose $e$-positivity and Schur-positivity has been of large interest. In this paper we study the relative $e$-positivity and Schur-positivity between connected graphs on $n$ vertices.
