Kaon Condensation in a Neutron Star under Strong Magnetic Fields by Using the Modified Quark-meson Coupling Model

C. Y. Ryu, S. W. Hong

We have considered the antikaon condensation in a neutron star in the presence of strong magnetic fields by using the modified quark-meson coupling (MQMC) model. The structure of t…

Neutrino induced reactions related to the $ν$ -process nucleosynthesis of $^{92}$ Nb and $^{98}$ Tc

Myung-Ki Cheoun, Eunja Ha, T. Hayakawa +4

It has recently been proposed that $_{41}^{92}$ Nb and $_{43}^{98}$ Tc may have been formed in the $ν$ -process. We investigate the neutrino induced reactions related to the $ν$ -p…

Roles of High-lying Excited States on Neutrino Reactions and the Gamow Teller strength for $^{40}$ Ar

Eunja Ha, Myung-Ki Cheoun

Neutrino reactions on $^{40}$ Ar via charged and neutral currents for detecting solar and core collapsing supernovae (SNe) neutrinos and the Gamow Teller strength are calculated by…

QHD equation of state for strongly magnetized neutron stars

Chung-Yeol Ryu, Myung-Ki Cheoun, Toshitaka Kajino +2

We investigate the quantum hadrodynamic equation of state for neutron stars (with and without including hyperons) in the presence of strong magnetic fields. The deduced masses and…

Giant Flexoelectric Effect in Ferroelectric Epitaxial Thin Films

Daesu Lee, A. Yoon, S. Y. Jang +5

We report on nanoscale strain gradients in ferroelectric HoMnO3 epitaxial thin films, resulting in a giant flexoelectric effect. Using grazing-incidence in-plane X-ray diffraction,…

Degeneracy pressure of relic neutrinos and cosmic coincidence problem

Tae Hoon Lee

We consider the universe as a huge $ν_{R}$ -sphere formed with degenerate relic neutrinos and suggest that its constant energy density play a role of an effective cosmological constan…

Time Dependent Quark Masses and Big Bang Nucleosynthesis Revisited

Myung-Ki Cheoun, Toshitaka Kajino, Motohiko Kusakabe +1

We reinvestigate the constraints from primordial nucleosynthesis on a possible time-dependent quark mass. The limits on such quark-mass variations are particularly sensitive to the…

Charge states and magnetic ordering in LaMnO3/SrTiO3 superlattices

Woo Seok Choi, D. W. Jeong, S. S. A. Seo +5

We investigated the magnetic and optical properties of [(LaMnO3)n/(SrTiO3)8]20 (n = 1, 2, and 8) superlattices grown by pulsed laser deposition. We found a weak ferromagnetic and s…

Asymptotically Static Universe

Seyen Kouwn, Joohan Lee, Tae Hoon Lee +2

We consider a cosmology in which the final stage of the Universe is neither accelerating nor decelerating, but approaches an asymptotic state where the scale factor becomes a const…

Parallel Algorithm for Calculation of the Exact Partition Function of a Lattice Polymer

Jae Hwan Lee, Seung-Yeon Kim, Julian Lee

We develop a parallel algorithm that calculates the exact partition function of a lattice polymer, by enumerating the number of conformations for each energy level. An efficient pa…

Exact partition function zeros and the collapse transition of a two-dimensional lattice polymer

Jae Hwan Lee, Seung-Yeon Kim, Julian Lee

We study the collapse transition of the lattice homopolymer on a square lattice by calculating the exact partition function zeros. The exact partition function is obtained by enume…

Step bunching-induced vertical lattice mismatch and crystallographic tilt in vicinal BiFeO3(001) films

T. H. Kim, S. H. Baek, S. Y. Jang +7

Epitaxial (001) BiFeO3 thin films grown on vicinal SrTiO3 substrates are under large anisotropic stress from the substrates. The variations of the crystallographic tilt angle and t…
