Role of orbital hybridization in anisotropic magnetoresistance
Hye-Won Ko, Hyeon-Jong Park, Gyungchoon Go +3
We theoretically and numerically show that longitudinal orbital currents in ferromagnets depend on the magnetization direction, which contribute to the anisotropic magnetoresistanc…
Numerical Computation of Spin-Transfer Torques for Antiferromagnetic Domain walls
Hyeon-Jong Park, Yunboo Jeong, Se-Hyeok Oh +5
We numerically compute current-induced spin-transfer torques for antiferromagnetic domain walls, based on a linear response theory in a tight-binding model. We find that, unlike fo…
Transport theory of coupled quantum dots based on auxiliary operator method
Jung Hyun Oh, D. Ahn, Vladimir Bubanja
We formulate the theory of electron transport through coupled-quantum dots by extending the auxiliary operator representation. By using the generating functional technique, we deri…
Current and noise expressions for radio-frequency single-electron transistors
Jung Hyun Oh, D. Ahn, S. W. Hwang
We derive self-consistent expressions of current and noise for single-electron transistors driven by time-dependent perturbations. We take into account effects of the electrical en…
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…
