Photon-Assisted Quasiparticle Transport and Andreev Transport through an Interacting Quantum Dot
Sam Young Cho, Kicheon Kang, Chang-Mo Ryu
Resonant tunneling through a quantum dot coupled to superconducting reservoirs in the presence of time-dependent external voltage has been studied. A general formula of the current…
Origin of the giant magnetic moments of Fe impurities on and in Cs films
S. K. Kwon, B. I. Min
To explore the origin of the observed giant magnetic moments () of Fe impurities on the surface and in the bulk of Cs films, we have performed the relativistic LSDA + U…
Phenomenological Theory of Superconductivity and Magnetism in HoDyNiBC
Hyeonjin Doh, Manfred Sigrist, B. K. Cho +1
The coexistence of the superconductivity and magnetism in the HoDyNiBC is studied by using Ginzburg-Landau theory. This alloy shows the coexistence and complex…
A study of the superconducting gap in RNiBC (R = Y, Lu) single crystals by inelastic light scattering
In-Sang Yang, M. V. Klein, S. L. Cooper +3
Superconductivity-induced changes in the electronic Raman scattering response were observed for the RNiBC (R = Y, Lu) system in different scattering geometries. In the supe…
Phase Separation Based on U(1) Slave-boson Functional Integral Approach to the t-J Model
Tae-Hyoung Gimm, Sung-Ho Suck Salk
We investigate the phase diagram of phase separation for the hole-doped two dimensional system of antiferromagnetically correlated electrons based on the U(1) slave-boson functiona…
Full Numerical Estimation of Neutrino Mixing Parameters from Solar Neutrino Data
Jai Sam Kim, C. W. Kim
We have numerically computed survival probabilities of solar neutrinos interacting with matter via MSW mechanism in the full three generation formalism with $Δm^2_{23}=2.2\times 10…
Conservation laws for a class of Third order Evolutionary differential systems
Sung Ho Wang
The conservation laws of the third order quasilinear scalar evolution equations are considered via differential system and characteristic cohomology. We find a subspace of 2 forms…
Microwave-induced constant voltage steps in surface junctions of Bi_{2}Sr_{2}CaCu_{2}O_{8+δ} single crystals
Yong-Joo Doh, Jinhee Kim, Kyu-Tae Kim +1
We have observed the zero-crossing steps in a surface junction of a mesa structure micro-fabricated on the surface of a Bi-2212 single crystal. With the application of microwave of…
Progressive evolution of tunneling characteristics of in-situ fabricated intrinsic Josephson junctions in Bi_2Sr_2CaCu_2O_{8+delta} single crystals
Yong-Joo Doh, Hu-Jong Lee, Hyun-Sik Chang
Stacks of a few intrinsic tunnel junctions were micro-fabricated on the surface of Bi-2212 single crystals. The number of junctions in a stack was tailored by progressively increas…
Effects of nonmagnetic impurities on optical conductivity in strongly correlated systems
Seung-Pyo Hong, Kwangyl Park, Sung-Ho Suck Salk
Effects of nonmagnetic impurities on optical conductivity in the systems of antiferromagnetically correlated electrons are examined based on the Lanczos exact diagonalization schem…
High Phase Diagram based on the SU(2) Slave-Boson Approach to the t-J Hamiltonian
Sung-Sik Lee, Sung-Ho Suck Salk
Based on an improved SU(2) slave-boson approach to the t-J Hamiltonian, we derive a phase diagram of high cuprates which displays both the superconducting and pseudogap phase…
Temperature-scaling behavior of the Hall conductivity for Hg-based superconducting thin films
