Note on Hamiltonicity of basis graphs of even delta-matroids
Donggyu Kim, Sang-il Oum
We show that the basis graph of an even delta-matroid is Hamiltonian if it has more than two vertices. More strongly, we prove that for two distinct edges and sharing a com…

Preparation of Entangled Many-Body States with Machine Learning
Donggyu Kim, Eun-Gook Moon
Preparation of a target quantum many-body state on quantum simulators is one of the significant steps in quantum science and technology. With a small number of qubits, a few quantu…

Orthogonal matroids over tracts
Tong Jin, Donggyu Kim
We generalize Baker-Bowler's theory of matroids over tracts to orthogonal matroids, define orthogonal matroids with coefficients in tracts in terms of Wick functions, orthogonal si…
