Green's function approach to transport through a gate-all-around Si nanowire under impurity scattering
J. H. OH, D. Ahn, Y. S. Yu +1
We investigate transport properties of gate-all-around Si nanowires using non-equilibrium Green's function technique. By taking into account of the ionized impurity scattering we c…
Dissipation of quantum information near the event horizon of Schwarzschild black holes
D. Ahn, S. W. Hwang
We found that the Wigner rotation of a particle with spin 1/2, which is unitary in Minkowski spacetime, becomes non-unitary as the particle is falling onto the black hole. This imp…
Time-dependent Currents of a Single-electron Transistor in Dissipative Environments
Jung Hyun Oh, D. Ahn, S. W. Hwang
Currents of the single-electron transistors driven by time-dependent fields via external dissipative circuits are investigated theoretically. By expressing the external circuit in…
Is quantum entanglement invariant in special relativity?
D. Ahn, H. J. Lee, S. W. Hwang +1
Quantum entanglements are of fundamental importance in quantum physics ranging from the quantum information processing to the physics of black hole. Here, we show that the quantum…
Electrical control of superposed quantum states evolution in quantum dot molecule by pulsed field
S. W. Hwang, D. Y. Jeong, M. S. Jun +4
Quantum computing (or generally, quantum information processing) is of prime interest for it potentially has a significant impact on present electronics and computations1-5. Essenc…
Relativity of Entanglement
W. Y. Hwang, J. Lee, D. Ahn +1
It has recently been suggested that various entanglement measures for bipartite mixed states do not in general give the same ordering even in the asymptotic cases [S. Virmani and M…
