Core-Shell Magneto-Optical Trap for Alkaline-Earth-Metal-Like Atoms
Jeongwon Lee, Jae Hoon Lee, Jiho Noh +1
We propose and demonstrate a new magneto-optical trap (MOT) for alkaline-earth-metal-like (AEML) atoms where the narrow transition and the broad $…
Room temperature magnetic order on zigzag edges of narrow graphene nanoribbons
Gabor Zsolt Magda, Xiaozhan Jin, Imre Hagymasi +6
Magnetic order emerging in otherwise non-magnetic materials as carbon is a paradigmatic example of a novel type of s-p electron magnetism predicted to be of exceptional high-temper…
Magnetic Bubblecade Memory
Kyoung-Woong Moon, Duck-Ho Kim, Sang-Cheol Yoo +6
Unidirectional motion of magnetic domain walls is the key concept underlying next-generation domain-wall-mediated memory and logic devices. Such motion has been achieved either by…
Neutron calibration facility with an Am-Be source for pulse shape discrimination measurement of CsI(Tl) crystals
H. S. Lee, H. Bhang, J. H. Choi +19
We constructed a neutron calibration facility based on a 300-mCi Am-Be source in conjunction with a search for weakly interacting massive particle candidates for dark matter. The f…
Experiences with a two terminal-pair digital impedance bridge
Luca Callegaro, Vincenzo D'Elia, Marian Kampik +3
This paper describes the realization of a two terminal-pair digital impedance bridge and the test measurements performed with it. The bridge, with a very simple architecture, is ba…
Substrate-supported thermometry platform for nanomaterials like graphene, nanotubes, and nanowires
Zuanyi Li, Myung-Ho Bae, Eric Pop
We demonstrate a substrate-supported thermometry platform to measure thermal conduction in nanomaterials like graphene, with no need to suspend them. We use three-dimensional simul…
Electrical Modulation of Superconducting Critical Temperature in Liquid-Gated Thin Niobium Films
Jiman Choi, Pradheesh R., Hyungsang Kim +3
We demonstrate that the superconducting critical temperature (Tc) of thin niobium films can be electrically modulated in a liquid-gated geometry device. Tc can be suppressed and en…
Tests on NaI(Tl) crystals for WIMP search at the Yangyang Underground Laboratory
K. W. Kim, W. G. Kang, S. Y. Oh +17
Among the direct search experiments for WIMP dark matter, the DAMA experiment observed an annual modulation signal interpreted as WIMP interactions with 9.2 significance. Howeve…
Search for bosonic superweakly interacting massive dark matter particles with the XMASS-I detector
K. Abe, K. Hieda, K. Hiraide +42
Bosonic superweakly interacting massive particles (super-WIMPs) are a candidate for warm dark matter. With the absorption of such a boson by a xenon atom these dark matter candidat…
Controlling the nanoscale rippling of graphene with SiO2 nanoparticles
Zoltán Osváth, Eszter Gergely-Fülöp, Norbert Nagy +5
The electronic properties of graphene can be significantly influenced by mechanical strain. One practical approach to induce strain in graphene is to transfer this atomically thin…
Quantum coherence and population transfer in a driven cascade three-level artificial atom
Sung Un Cho, Han Seb Moon, Young-Tak Chough +2
We present an experimental investigation on the spectral characteristics of an artificial atom "transmon qubit" constituting a three-level cascade system (Ξ-system) in the presence…
Search for Low-Mass Dark Matter with CsI(Tl) Crystal Detectors
H. S. Lee, H. Bhang, J. H. Choi +27
We present a search for low-mass () weakly interacting massive particles(WIMPs), strong candidates of dark matter particles,using the low-background CsI(Tl) dete…
Linear-response calculation of the effective Coulomb interaction between closed-shell localized electrons: Cu, Zn, and ZnO
Woo-Jin Lee, Yong-Sung Kim
A linear-response method to calculate the effective Coulomb interaction () between closed-shell localized electrons is suggested and applied to the closed-shell systems (Cu…
Charge frustration in a triangular triple quantum dot
M. Seo, H. K. Choi, S. -Y. Lee +5
We experimentally investigate the charge (isospin) frustration induced by a geometrical symmetry in a triangular triple quantum dot. We observe the ground-state charge configuratio…
Multi-Valued Logic Gates based on Ballistic Transport in Quantum Point Contacts
M. Seo, C. Hong, S. -Y. Lee +5
Multi-valued logic gates, which can handle quaternary numbers as inputs, are developed by exploiting the ballistic transport properties of quantum point contacts in series. The pri…
Thermal Model and Optimization of a Large Crystal Detector using a Metallic Magnetic Calorimeter
G. B. Kim, S. Choi, Y. S. Jang +9
We established a simple thermal model of the heat flow in a large crystal detector designed for a neutrinoless double beta decay experiment. The detector is composed of a CaMoO$_{4…
