Demonstration of Magnetic Confinement in graphene with Fano-type resonances
Journal of the Korean Physical Society, 2013Co-Authors: Nojoon Myoung, Kyungchul Seo, Gukhyung IhmAbstract:We demonstrate the Magnetic Confinement in graphene by investigating the Fano-type resonant features in the transmission spectra. The Fano-type resonance occurs due to the interference between extended states and Magnetically-bound states as a result of the interaction of Dirac fermions with the oscillating field. We also find another type of resonance that results from the quasi-bound states induced by the oscillating field. In contrast to the Magnetically-bound states, the quasibound states generally have complex eigenenergies whose imaginary parts are associated with finite lifetimes. The results may inspire experimental research on Magnetic Confinement in graphene.

Fano resonance in electronic transport induced by the Magnetic Confinement in a graphene nanoribbon
Current Applied Physics, 2013Co-Authors: Nojoon Myoung, Gukhyung Ihm, Kyungchul SeoAbstract:Abstract Based on the Floquet scattering theory, a model of graphene-based electronic device is presented, in which electrical transport is controlled by adjusting Dirac fermions energy near resonance conditions. The presence of an oscillating field leads to the Fano resonance in transport through a Magnetic structure in an armchair graphene nanoribbon (AGNR). The Fano resonance originates from bound states of the Magnetic Confinement, according to subband indices in the AGNR. The ballistic conductance is markedly affected by the Fano resonance due to the quasi-one-dimensional nature of AGNRs. The results may help realizing graphene electronics with the resonant characteristics in the conductance.

Roles of electric field on toroidal Magnetic Confinement
IEEE Transactions on Plasma Science, 1994Co-Authors: Kimitaka Itoh, Sanae-i. Itoh, Heiji Sanuki, Atsushi FukuyamaAbstract:Theoretical research on the influence of electric field on toroidal Magnetic Confinement is surveyed. The static electric field is first described. A physical picture of the radial electric field generation and its influence on Confinement are shown. Neoclassical effects as well as the non-classical processes are discussed. Emphasis is made on the connection with improved Confinement. Convective cells with a nonuniform potential on the Magnetic surface are also discussed. The roles of the fluctuating electric field are then reviewed. Recent progress in anomalous transport theory is addressed. Through these surveys, the impact of experiments using the heavy ion beam probes on modern plasma physics is illustrated. >

Progress in Magnetic Confinement fusion research
Contemporary Physics, 1998Co-Authors: T. N. Todd, C. G. WindsorAbstract:This article reviews the present status of research into controlled fusion using Magnetic Confinement of ionized gas or plasma. It concentrates on the world's leading Magnetic configurations for this purpose, comprising the conventional tokamak, stellarator, reversed field pinch and spherical tokamak. These configurations are described in some detail, along with an introduction to the basics of this line of fusion research, the progress so far and the principal scientific and technical problems outstanding. The environmental implications are briefly addressed, in the context of some power generation alternatives and every-day radiation exposures.
