Partition of Two Interacting Electrons by a Potential Barrier
Sungguen Ryu, H. -S. Sim
Scattering or tunneling of an electron at a potential barrier is a fundamental quantum effect. Electron-electron interactions often affect the scattering, and understanding of the…

Ultrafast Emission and Detection of a Single-Electron Gaussian Wave Packet: A Theoretical Study
Sungguen Ryu, M. Kataoka, H. -S. Sim
Generating and detecting a prescribed single-electron state is an important step towards solid-state fermion optics. We propose how to generate an electron in a Gaussian state, usi…

Minimax optimization of entanglement witness operator for the quantification of three-qubit mixed-state entanglement
Sungguen Ryu, Seung-Sup B. Lee, H. -S. Sim
We develop a numerical approach for quantifying entanglement in mixed quantum states by convex-roof entanglement measures, based on the optimal entanglement witness operator and th…
