Lattice and magnetic dynamics in YVO Mott insulator studied by neutron scattering and first-principles calculations
Yu Tao, Douglas L. Abernathy, Tianran Chen +5
The Mott insulator YVO with = 118 K is revisited to explore the role of spin, lattice and orbital correlations across the multiple structural and magnetic transitions…
GPU-accelerated path tracker for polyhedral homotopy
Tianran Chen
The polyhedral homotopy method of Huber and Sturmfels is a particularly efficient and robust numerical method for solving system of (Laurent) polynomial equations. A central compon…
Volume of convex polytopes equals mixed volume of simplices
Tianran Chen
This note provides a simple proof for the equality between the normalized volume of a convex polytope with vertices and the mixed volume of simplices and thus shows the see…
Facets and facet subgraphs of symmetric edge polytopes
Tianran Chen, Robert Davis, Evgeniia Korchevskaia
Symmetric edge polytopes, a.k.a. PV-type adjacency polytopes, associated with undirected graphs have been defined and studied in several seemingly independent areas including numbe…
