We study the two-dimensional complex theory at finite chemical potential using the tensor renormalization group. This model exhibits the Silver Blaze phenomenon in which bu…
Development of High-Speed Ion Conductance Microscopy
Shinji Watanabe, Satoko Kitazawa, Linhao Sun +2
Scanning ion conductance microscopy (SICM) can image the surface topography of specimens in ionic solutions without mechanical probe--sample contact. This unique capability is adva…
Horizon thermodynamics in holographic cosmological models with a power-law term
Nobuyoshi Komatsu
Thermodynamics on the horizon of a flat universe at late times is studied in holographic cosmological models that assume an associated entropy on the horizon. In such models, a $Λ(…
Robots Assembling Machines: Learning from the World Robot Summit 2018 Assembly Challenge
Felix von Drigalski, Christian Schlette, Martin Rudorfer +5
The Industrial Assembly Challenge at the World Robot Summit was held in 2018 to showcase the state-of-the-art of autonomous manufacturing systems. The challenge included various ta…
X-ray study of the double source plane gravitational lens system Eye of Horus observed with XMM-Newton
Keigo Tanaka, Ayumi Tsuji, Hiroki Akamatsu +19
A double source plane (DSP) system is a precious probe for the density profile of distant galaxies and cosmological parameters. However, these measurements could be affected by the…
Active gas features in three HSC-SSP CAMIRA clusters revealed by high angular resolution analysis of MUSTANG-2 SZE and XXL X-ray observations
Nobuhiro Okabe, Simon Dicker, Dominique Eckert +33
We present results from simultaneous modeling of high angular resolution GBT/MUSTANG-2 90 GHz Sunyaev-Zel'dovich effect (SZE) measurements and XMM-XXL X-ray images of three rich ga…
Bright gamma-ray flares observed in GRB131108A
Donggeun Tak, Z. Lucas Uhm, Bing Zhang
GRB 131108A is a bright long Gamma-Ray Burst (GRB) detected by the Large Area Telescope and the Gamma-ray Burst Monitor on board the Fermi Gamma-ray Space Telescope. Dedicated temp…
Thermally Driven Approach To Fill Sub-10-nm Pipettes with Batch Production
Linhao Sun, Kazuki Shigyou, Toshio Ando +1
Typically, utilization of small nanopipettes results in either high sensitivity or spatial resolution in modern nanoscience and nanotechnology. However, filling a nanopipette with…
First-principles Study of Spiral Spin Density Waves in Monolayer MnCl Using Generalized Bloch Theorem
Teguh Budi Prayitno, Fumiyuki Ishii
We investigated the spiral spin density waves in the monolayer 1T-MnCl for a set of spiral vectors based on first-principles calculations. The magnetic ground states were evalu…
Spectral analysis of Fermi-LAT gamma-ray bursts with known redshift and their potential use as cosmological standard candles
F. Fana Dirirsa, S. Razzaque, F. Piron +6
Long duration Gamma-Ray Bursts (LGRBs) may serve as standard candles to constrain cosmological parameters by probing the Hubble diagram well beyond the range of redshift currently…
Effect of the Surface Diffusion and Evaporation of Impurities on Step Bunching Induced by Impurities
Masahide Sato
We consider a vicinal face, where atoms and impurities impinge and evaporate to a vapor phase, to study how the surface diffusion and evaporation of impurities affect step bunching…
Gravitational waves from chiral phase transition in a conformally extended standard model
Mayumi Aoki, Jisuke Kubo
The gravitational wave (GW) background produced at the cosmological chiral phase transition in a conformal extension of the standard model is studied. To obtain the bounce solution…
Mean first passage times reconstruct the slowest relaxations in potential energy landscapes of nanoclusters
Teruaki Okushima, Tomoaki Niiyama, Kensuke S. Ikeda +1
Relaxation modes are the collective modes in which all probability deviations from equilibrium states decay with the same relaxation rates. In contrast, a first passage time is the…
Critical endpoint in the continuum limit and critical endline at of the finite temperature phase transition of QCD with clover fermions
Yoshifumi Nakamura, Yoshinobu Kuramashi, Hiroshi Ohno +1
We investigate the critical endpoints of the finite temperature phase transition of QCD at zero chemical potential. We employ the renormalization-group improved Iwasaki gauge actio…
Torus-covering knot groups and their irreducible metabelian -representations
Inasa Nakamura
A torus-covering -knot is a surface-knot of genus one determined from a pair of commutative braids. For a torus-covering -knot , we determine the number of irreducible…
A finite electric-field approach to evaluate the vertex correction for the screened Coulomb interaction in the quasiparticle self-consistent GW method
Hirofumi Sakakibara, Takao Kotani, Masao Obata +1
We apply the quasiparticle self-consistent GW method (QSGW) to slab models of ionic materials, LiF, KF, NaCl, MgO, and CaO, under electric field. Then we obtain the optical dielect…
