Photonic quantum ring laser
J. C. Ahn, K. S. Kwak, B. H. Park +3
We report a quantum ring-like toroidal cavity naturally formed in a vertical-cavity-like active microdisk plane due to Rayleigh's band of whispering gallery modes. The -d…
Holon Pair Condensation and Phase Diagram of High T_c Cuprates
T. -H. Gimm, S. -S. Lee, S. -P. Hong +1
A possibility of holon (boson) pair condensation is explored for hole doped high T_c cuprates, by using the U(1) slave-boson representation of the t-J Hamiltonian with the inclusio…
Quantum phase transitions in superconducting arrays under external magnetic fields
Beom Jun Kim, Gun Sang Jeon, M. -S. Choi +1
We study the zero-temperature phase transitions of two-dimensional superconducting arrays with both the self- and the junction capacitances in the presence of external magnetic fie…
Quantum Phase Transitions in Capacitively Coupled Two-Dimensional Josephson-Junction Arrays
Mahn-Soo Choi
Quantum-phase transitions in two layers of ultrasmall Josephson junctions, coupled capacitively with each other, are investigated. As the interlayer capacitance is increased, the s…
Suppressed Superconductivity of the Surface Conduction Layer in BiSrCaCuO Single Crystals Probed by {\it c}-Axis Tunneling Measurements
Nam Kim, Yong Joo Doh, Hyun-Sik Chang +1
We fabricated small-size stacks on the surface of BiSrCaCuO (BSCCO-2212) single crystals with the bulk transition temperature 90 K, each containing…
Statistical Mechanics of Membrane Protein Conformation: A Homopolymer Model
Pyeong Jun Park, W. Sung
The conformation and the phase diagram of a membrane protein are investigated via grand canonical ensemble approach using a homopolymer model. We discuss the nature and pathway of…
Current responses and voltage fluctuations in Josephson-junction systems
Mahn-Soo Choi, M. Y. Choi, Sung-Ik Lee
We consider arrays of Josephson junctions as well as single junctions in both the classical and quantum-mechanical regimes, and examine the generalized (frequency-dependent) resist…
Unlimited Vocabulary Grapheme to Phoneme Conversion for Korean TTS
Byeongchang Kim, WonIl Lee, Geunbae Lee +1
This paper describes a grapheme-to-phoneme conversion method using phoneme connectivity and CCV conversion rules. The method consists of mainly four modules including morpheme norm…
Cotunneling Transport and Quantum Phase Transitions in Coupled Josephson-Junction Chains with Charge Frustration
Mahn-Soo Choi, M. Y. Choi, Taeseung Choi +1
We investigate the quantum phase transitions in two capacitively coupled chains of ultra-small Josephson-junctions, with emphasis on the external charge effects. The particle-hole…
Mirror Symmetry and Toric Degenerations of Partial Flag Manifolds
Victor V. Batyrev, Ionut Ciocan-Fontanine, Bumsig Kim +1
In this paper we propose and discuss a mirror construction for complete intersections in partial flag manifolds . This construction includes our previous mirro…
Multi-anyons in the magnetic field
Taeseung Choi, Chang-Mo Ryu, Chul Koo Kim
We consider the external magnetic field effects on the two types of anyon with fractional statistical parameters with coprimes and , one with fractional charge …
Capacitively coupled Josephson-junction chains: straight and slanted coupling
Mahn-Soo Choi
Two chains of ultrasmall Josephson junctions, coupled capacitively with each other in the two different ways, straight and slanted coupling, are considered. As the coupling capacit…
Quantum Phase Transitions and Particle-Hole Pair Transport in Capacitively Coupled Josephson-Junction Chains
Mahn-Soo Choi, M. Y. Choi, Sung-Ik Lee
We consider two chains of ultrasmall Josephson junctions, coupled capacitively with each other, and investigate the transport of particle-hole pairs and the quantum phase transitio…
Polymer translocation induced by adsorption
Pyeong Jun Park, Wokyung Sung
We study the translocation of a flexible polymer through a pore in a membrane induced by its adsorption on \trans side of the membrane. When temperature is higher than , t…
Polymer Release out of a Spherical Vesicle through a Pore
Pyeong Jun Park, Wokyung Sung
Translocation of a polymer out of curved surface or membrane is studied via mean first passage time approach. Membrane curvature gives rise to a constraint on polymer conformation,…
Polymer Translocation througha Pore in a Membrane
W. Sung, P. J. Park
We construct a new statistical physical model of polymer translocation through a pore in a membrane treated as the diffusion process across a free energy barrier. We determine the…
Directional dependence of spin currents induced by Aharonov-Casher phase
Taeseung Choi, Chang-Mo Ryu, A. M. Jayannavar
We have calculated the persistent spin current of an open ring induced by the Aharonov-Casher phase. For unpolarized electrons there exist no persistent charge currents, but persis…
