Prandtl-Meyer Reflection for Supersonic Flow past a Solid Ramp
Myoungjean Bae, Gui-Qiang Chen, Mikhail Feldman
We present our recent results on the Prandtl-Meyer reflection for supersonic potential flow past a solid ramp. When a steady supersonic flow passes a solid ramp, there are two poss…
Pressure-induced Phonon Softenings and the Structural and Magnetic Transitions in CrO
Sooran Kim, Kyoo Kim, Chang-Jong Kang +1
To investigate the pressure-induced structural transitions of chromium dioxide (CrO), phonon dispersions and total energy band structures are calculated as a function of pres…
On the Vlasov-Poisson-Fokker-Planck equation near Maxwellian
Hyung Ju Hwang, Juhi Jang
We establish the exponential time decay rate of smooth solutions of small amplitude to the Vlasov-Poisson-Fokker-Planck equations to the Maxwellian both in the whole space and in t…
Robust nodal superconductivity induced by isovalent doping in Ba(FeRu)As and BaFe(AsP)
X. Qiu, S. Y. Zhou, H. Zhang +9
We present the ultra-low-temperature heat transport study of iron-based superconductors Ba(FeRu)As and BaFe(AsP). For optimally doped Ba(Fe$…
Detecting Chiral Orbital Angular Momentum by Circular Dichroism ARPES
Jin-Hong Park, Choong H. Kim, Jun Won Rhim +1
We show, by way of tight-binding and first-principles calculations, that a one-to-one correspondence between electron's crystal momentum k and non-zero orbital angular momentum (OA…
New insights in quantum geometry
Hanno Sahlmann
Quantum geometry, i.e., the quantum theory of intrinsic and extrinsic spatial geometry, is a cornerstone of loop quantum gravity. Recently, there have been many new ideas in this f…
Effects of static and temporally fluctuating tensions on semiflexible polymer looping
Jaeoh Shin, Wokyung Sung
Biopolymer looping is a dynamic process that occurs ubiquitously in cells for gene regulation, protein folding, etc. In cellular environments, biopolymers are often subject to tens…
Effects of the Spin-Orbit Coupling and the Superconductivity in simple-cubic alpha-Polonium
Chang-Jong Kang, Kyoo Kim, B. I. Min
We have investigated the mechanism of stabilizing the simple-cubic (SC) structure in polonium (alpha- Po), based on the phonon dispersion calculations using the first-principles al…
Four-nucleon contact interactions from holographic QCD
Youngman Kim, Deokhyun Yi, Piljin Yi
We calculate the low energy constants of four-nucleon interactions in an effective chiral Lagrangian in holographic QCD. We start with a D4-D8 model to obtain meson-nucleon interac…
Ab initio calculation of d-d excitations in quasi-one-dimensional Cu d9 correlated materials
Hsiao-Yu Huang, Nikolay A. Bogdanov, Liudmila Siurakshina +3
With wavefunction-based electronic-structure calculations we determine the Cu d-d excitation energies in quasi-one-dimensional spin-chain and ladder copper oxides. A complete set o…
Structures and lower bounds for binary covering arrays
Soohak Choi, Hyun Kwang Kim, Dong Yeol Oh
A -ary -covering array is an matrix with entries from with the property that for any column positions, all possible vectors of len…
Restriction of Fourier transforms to some complex curves
Jong-Guk Bak, Seheon Ham
The purpose of this paper is to prove a Fourier restriction estimate for certain 2-dimensional surfaces in , . These surfaces are defined by a complex curve $γ(z…
Central-moment description of polarization for quantum states of light
G. Björk, J. Söderholm, Y. -S. Kim +6
We present a moment expansion method for the systematic characterization of the polarization properties of quantum states of light. Specifically, we link the method to the measurem…

We find the realization of large converse magnetoelectric (ME) effects at room temperature in a multiferroic hexaferrite BaSrCoFeO single crys…
Nanoscale inhomogeneities: A new path toward high Curie temperature ferromagnetism in diluted materials
Akash Chakraborty, Richard Bouzerar, Stefan Kettemann +1
Room temperature ferromagnetism has been one of the most sought after topics in today's emerging field of spintronics. It is strongly believed that defect- and inhomogeneity- free…
Magnetization dynamics induced by in-plane currents in ultrathin magnetic nanostructures
Kyoung-Whan Kim, Soo-Man Seo, Jisu Ryu +2
Ultrathin magnetic systems have properties qualitatively different from their thicker counterparts, implying that different physics governs their properties. We demonstrate that va…
