Study of Asymptotic Velocity in the Bondi-Hoyle Accretion Flows in the Domain of Kerr and 4-D Einstein-Gauss-Bonnet Gravities
Orhan Donmez, Fatih Dogan, Tugba Sahin
Understanding the physical structures of the accreated matter very close to the black hole in quasars and active galactic nucleus (AGNs) is an important milestone to constrain the…
Tailoring spin-orbit torque in diluted magnetic semiconductors
Hang Li, Xuhui Wang, Fatih Dogan +1
We study the spin orbit torque arising from an intrinsic linear Dresselhaus spin-orbit coupling in a single layer III-V diluted magnetic semiconductor. We investigate the transport…
Emerging nonequilibrium bound state in spin-current-local-spin scattering
Fatih Dogan, Lucian Covaci, Wonkee Kim +1
Magnetization reversal is a well-studied problem with obvious applicability in computer hard-drives. One can accomplish a magnetization reversal in at least one of two ways: applic…
Electron and Spin Transport in the Presence of Complex Absorbing Potential
Fatih Dogan, Wonkee Kim, C. M. Blois +1
We examine the impact of a complex absorbing potential on electron transport, both in the continuum and on a lattice. This requires the use of non-Hermitian Hamiltonians; the requi…
Quantum mechanics of spin transfer in coupled electron-spin chains
Wonkee Kim, L. Covaci, F. Dogan +1
The manner in which spin-polarized electrons interact with a magnetized thin film is currently described by a semi-classical approach. This in turn provides our present understandi…
Magnetic Excitations and their energy change available to Superconducting Condensation in Optimally Doped YBaCuO
Hyungje Woo, Pengcheng Dai, S. M. Hayden +5
Understanding the magnetic excitations in high-transition temperature (high-) copper oxides is important because they may mediate the electron pairing for superconductivity. B…
