Topological Multivortex Solutions of the Self-Dual Maxwell-Chern-Simons-Higgs System
Dongho Chae, Namkwon Kim
We study existence and various behaviors of topological multivortices solutions of the relativistic self-dual Maxwell-Chern-Simons-Higgs system. We first prove existence of general…
Quantum Phase Transitions in Josephson Junction Chains
Mahn-Soo Choi, J. Yi, M. Y. Choi +2
We investigate the quantum phase transition in a one-dimensional chain of ultra-small superconducting grains, considering both the self- and junction capacitances. At zero temperat…
Dissipative Dynamics of Quantum Vortices in Superconducting Arrays
Mahn-Soo Choi, Sung-Ik Lee, M. Y. Choi
We consider a two-dimensional array of ultra-small superconducting grains, weakly coupled by Josephson junctions with large charging energy. We start from an effective action based…
Magnetic Penetration Depth in a Superconductor
Sang Boo Nam
It is shown that the notion of the finite pairing interaction energy range results in a linear temperature dependence of the London magnetic penetration depth $Δλ/ λ(0) = (T/…
Pairing Theory of High and Low Temperature Superconductors
Sang Boo Nam
A scenario which can account for all observed features of both high- superconductors (HTS) and low- superconductors (LTS) is discussed. This scenario is based on the fact…
New Vortex with Zero Fluxoid Quantum in a Superconductor Anomalous Hall Effect in High T_c and Low T_c Superconductors
Sang Boo Nam
It is shown that there are three kinds of vortices in a superconductor; a vortex with the fluxoid quantum 1 (VF), a new vortex with 0 (VZF), and a vortex with -1 (VAF), respectivel…
Charge ordering in doped manganese oxides: lattice dynamics and magnetic structure
J. D. Lee, B. I. Min
Based on the Hamiltonian of small polarons with the strong nearest neighbor repulsion, we have investigated the charge ordering phenomena observed in half-doped manganites R_{1/2}A…
Polaron transport and lattice dynamics in colossal magnetoresistance manganites
J. D. Lee, B. I. Min
Based on the model combining the spin double exchange and the lattice polaron, we have studied the colossal magnetoresistance phenomena observed in perovskite manganites R_{1-x}A_x…
Effect of Quantum Confinement on Electron Tunneling through a Quantum Dot
Kicheon Kang, B. I. Min
Employing the Anderson impurity model, we study tunneling properties through an ideal quantum dot near the conductance minima. Considering the Coulomb blockade and the quantum conf…
Effects of Electron Correlations on Hofstadter Spectrum
Hyeonjin Doh, Seung-Pyo Hong, Sung-Ho Suck Salk
By allowing interactions between electrons, a new Harper's equation is derived to examine the effects of electron correlations on the Hofstadter energy spectra. It is shown that th…
Anisotropic strains and magnetoresistance of La_{0.7}Ca_{0.3}MnO_{3}
T. Y. Koo, S. H. Park, K. B. Lee +1
Thin films of perovskite manganite La_{0.7}Ca_{0.3}MnO_{3} were grown epitaxially on SrTiO_3(100), MgO(100) and LaAlO_3(100) substrates by the pulsed laser deposition method. Micro…
