Subdivisions of root polytopes, generalized tropical oriented matroids, and generalized matching ensembles
Tianyu Jiang, Yuan Yao, Qingyue Yu +1
The paper extends tropical oriented matroids and proves they correspond bijectively to subdivisions of root polytopes (sub‑polytopes of a product of two simplices), and also genera…

On the hardness of learning ground state entanglement of geometrically local Hamiltonians
Adam Bouland, Chenyi Zhang, Zixin Zhou
Characterizing the entanglement structure of ground states of local Hamiltonians is a fundamental problem in quantum information. In this work we study the computational complexity…
