Gigantic Impact of Magnetic Impurity on Stripe Order in LaSrCuO (1/8)

M. Fujita, M. Enoki, S. Iikubo +3

Precise neutron-scattering experiments on LaSrCuRO (=0 for R=Cu, Zn and =0.01 for R=Ga, Fe) were performed to examine the stabilit…

Probing the faint end of the quasar luminosity function at z ~ 4 in the COSMOS field

H. Ikeda, T. Nagao, K. Matsuoka +16

We searched for quasars that are ~ 3 mag fainter than the SDSS quasars in the redshift range 3.7 < z < 4.7 in the COSMOS field to constrain the faint end of the quasar luminosity f…

Neutron-scattering study of spin correlations in La1.94-xSrxCe0.06CuO4

M. Enoki, M. Fujita, K. Yamada

We performed a neutron-scattering experiment to investigate the effect of distortion of CuO2 planes on the low-energy spin correlation of La1.94-xSrxCe0.06CuO4 (LSCCO). Due to the…

Unravelling local spin polarization of Zhang-Rice singlet in lightly hole-doped cuprates using high-energy optical conductivity

Iman Santoso, Wei Ku, Tomonori Shirakawa +11

Unrevealing local magnetic and electronic correlations in the vicinity of charge carriers is crucial in order to understand rich physical properties in correlated electron systems.…

Investigation of the spin-glass regime between the antiferromagnetic and superconducting phases in FeSeTe

N. Katayama, S. Ji, D. Louca +12

Using bulk magnetization along with elastic and inelastic neutron scattering techniques, we have investigated the phase diagram of FeSeTe and the nature of ma…

The Hyper Suprime-Cam SSP Survey: Overview and Survey Design

H. Aihara, N. Arimoto, R. Armstrong +139

Hyper Suprime-Cam (HSC) is a wide-field imaging camera on the prime focus of the 8.2m Subaru telescope on the summit of Maunakea in Hawaii. A team of scientists from Japan, Taiwan…

Star formation history of galaxies from z=0 to z=0.7 A backward approach to the evolution of star-forming galaxies

V. Buat, S. Boissier, D. Burgarella +6

We investigate whether the mean star formation activity of star-forming galaxies from z=0 to z=0.7 in the GOODS-S field can be reproduced by simple evolution models of these system…

Spin-stripe density varies linearly with hole content in single-layer Bi2201 cuprate

M. Enoki, M. Fujita, T. Nishizaki +5

We have performed inelastic neutron scattering measurements on the single-layer cuprate Bi2+xSr2-xCuO6+y (Bi2201) with x=0.2, 0.3, 0.4 and 0.5, a doping range that spans the spin-g…

The Quasar-LBG Two-point Angular Cross-correlation Function at z ~ 4 in the COSMOS Field

H. Ikeda, T. Nagao, Y. Taniguchi +15

In order to investigate the origin of quasars, we estimate the bias factor for low-luminosity quasars at high redshift for the first time. In this study, we use the two-point angul…

Constraints on the faint end of the quasar luminosity function at z~5 in the COSMOS field

H. Ikeda, T. Nagao, K. Matsuoka +12

We present the result of our low-luminosity quasar survey in the redshift range of 4.5 < z < 5.5 in the COSMOS field. Using the COSMOS photometric catalog, we selected 15 quasar ca…

Hidden itinerant-spin phase in heavily-overdoped La2-xSrxCuO4 revealed by dilute Fe doping: A combined neutron scattering and angle-resolved photoemission study

Rui-Hua He, M. Fujita, M. Enoki +9

We demonstrated experimentally a direct way to probe a hidden propensity to the formation of spin density wave (SDW) in a non-magnetic metal with strong Fermi surface nesting. Subs…

Thermodynamic origin of solute-enriched stacking-fault in dilute Mg-Zn-Y alloys

M. Egami, I. Ohnuma, M. Enoki +2

We investigate thermodynamic behaviors of dilute Mg-Zn-Y ternary alloys to form a unique solute-enriched stacking-fault (SESF), which is an intrinsic-II type stacking-fault (I2-SF)…
