Prediction of spin orientations in terms of HOMO-LUMO interactions using spin-orbit coupling as perturbation
Myung-Hwan Whangbo, Elijah E. Gordon, Hongjun Xiang +2
The preferred spin orientation of a magnetic ion can be predicted on the basis of density functional theory (DFT) calculations including electron correlation and spin-orbit couplin…
Time-evolution of holographic entanglement entropy and metric perturbations
Nakwoo Kim, Jung Hun Lee
We study the holographic entanglement entropy under small deformations of AdS, including time-dependence. It is found through perturbative analysis that the divergent terms are not…
Planck cold clumps in the Orionis complex: I. Discovery of an extremely young Class 0 protostellar object and a proto-brown dwarf candidate in a bright rimmed clump PGCC G192.32-11.88
Tie Liu, Qizhou Zhang, Kee-Tae Kim +37
We are performing a series of observations with ground-based telescopes toward Planck Galactic cold clumps (PGCCs) in the Orionis complex in order to systematically investigate…
A New Calibrated Sunspot Group Series Since 1749: Statistics of Active Day Fractions
I. G. Usoskin, G. A. Kovaltsov, M. Lockwood +3
Although the sunspot-number series have existed since the mid-19th century, they are still the subject of intense debate, with the largest uncertainty being related to the "calibra…
Near-Infrared Polarization Source Catalog of the Northeastern Regions of the Large Magellanic Cloud
Jaeyeong Kim, Woong-Seob Jeong, Soojong Pak +2
We present a near-infrared band-merged photometric and polarimetric catalog for the 39$\arcmin$ 69$\arcmin$ fields on the northeastern part of the Large Magellanic Cloud (…
Is an axizilla possible for di-photon resonance?
Jihn E. Kim
Heavy axion-like particles, called axizillas, are simple extensions of the standard model(SM). An axizilla is required not to couple to the quarks, leptons, and Brout-Englert-Higgs…
Dynamic Clustering and ON/OFF Strategies for Wireless Small Cell Networks
Sumudu Samarakoon, Mehdi Bennis, Walid Saad +1
In this paper, a novel cluster-based approach for maximizing the energy efficiency of wireless small cell networks is proposed. A dynamic mechanism is proposed to group locally-cou…
Magneto-static modelling of the mixed plasma Beta solar atmosphere based on SUNRISE/IMaX data
T. Wiegelmann, T. Neukirch, D. H. Nickeler +3
Our aim is to model the 3D magnetic field structure of the upper solar atmosphere, including regions of non-negligible plasma beta. We use high-resolution photospheric magnetic fie…
Direct Spectral Detection: An Efficient Method to Detect and Characterize Binary Systems
Kevin Gullikson, Adam Kraus, Sarah Dodson-Robinson +6
Young, intermediate-mass stars are experiencing renewed interest as targets for direct-imaging planet searches. However, these types of stars are part of multiple systems more ofte…
Solar magnetoconvection and small-scale dynamo: Recent developments in observation and simulation
J. M. Borrero, S. Jafarzadeh, M. Schüssler +1
A number of observational and theoretical aspects of solar magnetoconvection are considered in this review. We discuss recent developments in our understanding of the small-scale s…
A statistical study of decaying kink oscillations detected using SDO/AIA
C. R. Goddard, G. Nistic`o, V. M. Nakariakov +1
Despite intensive studies of kink oscillations of coronal loops in the last decade, a large scale statistically significant investigation of the oscillation parameters has not been…
Discovery of A Faint Quasar at z~6 and Implications for Cosmic Reionization
Yongjung Kim, Myungshin Im, Yiseul Jeon +15
Recent studies suggest that faint active galactic nuclei may be responsible for the reionization of the universe. Confirmation of this scenario requires spectroscopic identificatio…
Variation of the Mn I 539.4 nm line with the solar cycle
S. Danilovic, S. K. Solanki, W. Livingston +2
As a part of the long-term program at Kitt Peak National Observatory (KPNO), the Mn I 539.4 nm line has been observed for nearly three solar cycles using the McMath telescope and t…
Stability theorem of depolarizing channels for the minimal output quantum Rényi entropies
Eunok Bae, Gilad Gour, Soojoon Lee +2
We show that the stability theorem of the depolarizing channel holds for the output quantum -Rényi entropy for or , which is an extension of the well known case $…
Quantum non-signalling assisted zero-error classical capacity of qubit channels
Jeonghoon Park, Soojoon Lee
In this paper, we explicitly evaluate the one-shot quantum non-signalling assisted zero-error classical capacities $\M_0^{\mathrm{QNS}}$ for qubit channels. In particular, we show…
Joint Deployment of Small Cells and Wireless Backhaul Links in Next-Generation Networks
Xiangxiang Xu, Walid Saad, Xiujun Zhang +2
In this paper, a novel approach for optimizing the joint deployment of small cell base stations and wireless backhaul links is proposed. This joint deployment scenario is cast as a…
Ferroelectric polarization switching with a remarkably high activation-energy in orthorhombic GaFeO3 thin films
Seungwoo Song, Hyun Myung Jang, Nam-Suk Lee +5
Orthorhombic GaFeO3 (o-GFO) with the polar Pna21 space group is a prominent ferrite by virtue of its piezoelectricity and ferrimagnetism, coupled with magneto-electric effects. Her…
