Macroscopic evidence for quantum criticality and field-induced quantum fluctuations in cuprate superconductors
A. D. Beyer, V. S. Zapf, H. Yang +5
We present macroscopic experimental evidence for field-induced microscopic quantum fluctuations in different hole- and electron-type cuprate superconductors with varying doping lev…
Josephson-vortex-flow terahertz emission in layered high- superconducting single crystals
Myung-Ho Bae, Hu-Jong Lee, Jae-Hyun Choi
We report on the successful terahertz emission (0.61 THz) that is continuous and tunable in its frequency and power, by driving Josephson vortices in resonance with the colle…
Collective Josephson vortex dynamics in a finite number of intrinsic Josephson junctions
Myung-Ho Bae, Jae-Hyun Choi, Hu-Jong Lee
We report the experimental confirmation of the collective transverse plasma modes excited by the Josephson vortex lattice in stacks of intrinsic Josephson junctions in BiSr$_…
Ballistic spin field-effect transistors: Multichannel effects
Jae-Seung Jeong, Hyun-Woo Lee
We study a ballistic spin field-effect transistor (SFET) with special attention to the issue of multi-channel effects. The conductance modulation of the SFET as a function of the R…
Correlation-induced resonances and population switching in a quantum dot coulomb valley
Hyun-Woo Lee, Sejoong Kim
Strong correlation effects on electron transport through a spinless quantum dot are considered. When two single-particle levels in the quantum dot are degenerate, a conserved pseud…
Topological minimal genus and -signatures
Jae Choon Cha
We obtain new lower bounds of the minimal genus of a locally flat surface representing a 2-dimensional homology class in a topological 4-manifold with boundary, using the von Neuma…
Injectivity theorems and algebraic closures of groups with coefficients
Jae Choon Cha
Recently, Cochran and Harvey defined torsion-free derived series of groups and proved an injectivity theorem on the associated torsion-free quotients. We show that there is a unive…
Baryons in AdS/QCD
Deog Ki Hong, Takeo Inami, Ho-Ung Yee
We construct a holographic model for baryons in the context of AdS/QCD and study the spin-1/2 nucleon spectra and its couplings to mesons, taking fully account of the effects from…
Recursive relations for a quiver gauge theory
Jaemo Park, Woojoo Sim
We study the recursive relations for a quiver gauge theory with the gauge group with bifundamental fermions transforming as . We work out t…
Initial growth behavior and resulting microstructural properties of heteroepitaxial ZnO thin films on sapphire (0001) substrates
C. Liu, S. H. Chang, T. W. Noh +5
We have investigated the initial growth behavior and resulting microstructural properties of heteroepitaxial ZnO thin films prepared by pulsed laser deposition on sapphire (0001) s…
Dynamic critical behaviors in two-dimensional Josephson junction arrays with positional disorder
Jaegon Um, Beom Jun Kim, Petter Minnhagen +2
We numerically investigate dynamic critical behaviors of two-dimensional (2D) Josephson-junction arrays with positional disorder in the scheme of the resistively shunted junction d…
The case for the bulk nature of the spectroscopic Luttinger liquid signatures observed in angle resolved photoemission of Li0.9Mo6O17
Feng Wang, S. -K. Mo, J. W. Allen +7
Angle resolved photoemission spectroscopy (ARPES) has been performed on quasi-one dimensional Li0.9Mo6O17 using photon energy 500 eV. Measured band dispersions are in agreement wit…
Photoemission study of (VM)O (M=Cr, Ti)
S. -K. Mo, H. -D. Kim, J. D. Denlinger +8
We present high-resolution bulk-sensitive photoemission spectra of (VM)O (M=Cr, Ti). The measurements were made for the paramagnetic metal (PM), paramagnetic in…
Late Hadronization and Matter Formed at RHIC: Vector Manifestation, Brown-Rho Scaling and Hadronic Freedom
Gerald E. Brown, Jeremy W. Holt, Chang-Hwan Lee +1
Recent developments in our description of RHIC and related heavy-ion phenomena in terms of hidden local symmetry theories are reviewed with a focus on the novel nearly massless sta…
Market Efficiency in Foreign Exchange Markets
Gabjin Oh, Seunghwan Kim, Cheoljun Eom
We investigate the relative market efficiency in financial market data, using the approximate entropy(ApEn) method for a quantification of randomness in time series. We used the gl…
Instanton interpolating current for --tetraquark
Hee-Jung Lee, N. I. Kochelev
We perform a QCD sum rule analysis for the light scalar meson () with a tetraquark current related to the instanton picture for QCD vacuum. We demonstrate that instan…
Pair Tunneling and shot noise through a single molecule in a strong electron-phonon coupling
Myung-Joong Hwang, Mahn-Soo Choi, Rosa Lopez
We investigate the electronic transport through a single molecule in a strong electron-phonon coupling regime. Based on a particle-hole transformation which is made suitable for no…

Age Andreas Falnes Olsen, Tom Henning Johansen, Daniel Shantsev +4
Magneto-optical imaging was used to observe flux dendrites with opposite polarities simultaneously penetrate superconducting, ring-shaped MgB films. By applying a perpendicular…
