Magnetization dynamics induced by in-plane currents in ultrathin magnetic nanostructures
Kyoung-Whan Kim, Soo-Man Seo, Jisu Ryu +2
Ultrathin magnetic systems have properties qualitatively different from their thicker counterparts, implying that different physics governs their properties. We demonstrate that va…
Signatures of asymmetric and inelastic tunneling on the spin torque bias dependence
A. Manchon, S. Zhang, K. -J. Lee
The influence of structural asymmetries (barrier height and exchange splitting), as well as inelastic scattering (magnons and phonons) on the bias dependence of the spin transfer t…
Spin Hall Effect-driven Spin Torque in Magnetic Texture
Aurelien Manchon, Kyung-Jin Lee
Current-induced spin torque and magnetization dynamics in the presence of spin Hall effect in magnetic textures is studied theoretically. The local deviation of the charge current…
Interferometric and noise signatures of Majorana fermion edge states in transport experiments
Grégory Strübi, Wolfgang Belzig, Mahn-Soo Choi +1
Domain walls between superconducting and magnetic regions placed on top of a topological insulator support transport channels for Majorana fermions. We propose to study noise corre…
Electrically Tunable Macroscopic Quantum Tunneling in a Graphene-based Josephson Junction
Gil-Ho Lee, Dongchan Jeong, Jae-Hyun Choi +2
Stochastic switching-current distribution in a graphene-based Josephson junction exhibits a crossover from the classical to quantum regime, revealing the macroscopic quantum tunnel…
Effect of spin diffusion on current generated by spin motive force
Kyoung-Whan Kim, Jung-Hwan Moon, Kyung-Jin Lee +1
Spin motive force is a spin-dependent force on conduction electrons induced by magnetization dynamics. In order to examine its effects on magnetization dynamics, it is indispensabl…
Scaling properties of induced density of chiral and non-chiral Dirac fermions in magnetic fields
P. S. Park, S. C. Kim, S. -R. Eric Yang
We find that a repulsive potential of graphene in the presence of a magnetic field has bound states that are peaked inside the barrier with tails extending over \ell(N + 1), where…
Finite Size Effect on Nanomechanical Mass Detection: Role of Surface Elasticity
Mai Duc Dai, Chang-Wan Kim, Kilho Eom
Nanomechanical resonators have recently been highlighted because of their remarkable ability to perform the sensing and detection. Since the nanomechanical resonators are character…
Nanomechanical Resonators and Their Applications in Biological/Chemical Detection: Nanomechanics Principles
Kilho Eom, Harold S. Park, Dae Sung Yoon +1
Recent advances in nanotechnology have led to the development of nano-electro-mechanical systems (NEMS) such as nanomechanical resonators, which have recently received significant…
Above-gap Conductance Anomaly Studied in Superconductor-graphene-superconductor Josephson Junctions
Jae-Hyun Choi, Hu-Jong Lee, Yong-Joo Doh
We investigated the electrical transport properties of superconductor-graphene-superconductor (SGS) Josephson junctions. In low voltage bias, we observed conventional proximity-cou…
Observation of Supercurrent in PbIn-Graphene-PbIn Josephson Junction
Dongchan Jeong, Jae-Hyun Choi, Gil-Ho Lee +3
Superconductor-graphene-superconductor (SGS) junction provides a unique platform to study relativistic electrodynamics of Dirac fermions combined with proximity-induced superconduc…
Many-body Correlation Effect on Mesoscopic Charge Relaxation
Minchul Lee, Rosa Lopez, Mahn-Soo Choi +2
We investigate in a nonperturbative way the dynamics of a correlated quantum capacitor. We find that the many-body correlations do not disturb the universal low-frequency relaxatio…
