Classifying Patents Based on their Semantic Content
Antonin Bergeaud, Yoann Potiron, Juste Raimbault
In this paper, we extend some usual techniques of classification resulting from a large-scale data-mining and network approach. This new technology, which in particular is designed…
Spontaneous Distortion and Ferromagnetism Induced by Quantum-well States in Pd(100) Ultrathin Films
Shunsuke Sakuragi, Hiroo Tajiri, Hiroyuki Kageshima +1
We study the crystal structure of Pd(100) ultrathin films, which show ferromagnetism induced by the quantum confinement effect, using in-situ X-ray crystal truncation rod measureme…
Kinematics of Ultra-High-Velocity Gas in the Expanding Molecular Shell adjacent to the W44 Supernova Remnant
Masaya Yamada, Tomoharu Oka, Shunya Takekawa +6
We mapped the ultra-high-velocity feature (the "Bullet") detected in the expanding molecular shell associated with the W44 supernova remnant using the Nobeyama Radio Observatory 45…
Ground-state thermodynamic quantities of homogeneous spin- fermions from the BCS region to the unitarity limit
Munekazu Horikoshi, Masato Koashi, Hiroyuki Tajima +2
We experimentally determined various thermodynamic quantities of interacting two-component fermions at the zero-temperature limit from the Bardeen-Cooper-Schrieffer (BCS) region to…
Physical Contact between the +20 km/s Cloud and the Galactic Circumnuclear Disk
Shunya Takekawa, Tomoharu Oka, Kunihiko Tanaka
This paper reports the discovery of evidence for physical contact between the Galactic circumnuclear disk (CND) and an exterior giant molecular cloud. The central 10 pc of our Gala…
A statistical study of giant molecular clouds traced by CO, CO, CS, and CHOH in the disk of NGC 1068 based on ALMA observations
Tomoka Tosaki, Kotaro Kohno, Nanase Harada +7
We present (98 pc) resolution ALMA observations of CO(=1-0), CO(=1-0), CS(=2-1) and CHOH(=-) molecular lines in the central (…
Low-energy Effective Worldsheet theory of a non-Abelian vortex in high-density QCD Revisited: A regular gauge construction
Chandrasekhar Chatterjee, Muneto Nitta
Color symmetry is spontaneously broken in quark matter at high density as a consequence of di-quark condensations with exhibiting color superconductivity. Non-Abelian vortices or c…
Collective excitations of a quantized vortex in superfluids in neutron stars
Chandrasekhar Chatterjee, Mareike Haberichter, Muneto Nitta
We discuss collective excitations (both fundamental and solitonic excitations) of quantized superfluid vortices in neutron superfluids, which likely exist in high density n…
Alleviating Overfitting for Polysemous Words for Word Representation Estimation Using Lexicons
Yuanzhi Ke, Masafumi Hagiwara
Though there are some works on improving distributed word representations using lexicons, the improper overfitting of the words that have multiple meanings is a remaining issue det…
Magnetic field sensitivity and decoherence spectroscopy of an ensemble of narrow-linewidth nitrogen-vacancy centers close to a diamond surface
Kento Sasaki, Ed E. Kleinsasser, Zhouyang Zhu +5
We perform pulsed optically detected electron spin resonance to measure the DC magnetic field sensitivity and electronic spin coherence time T_2 of an ensemble of near-surface, hig…
Chiral transport of neutrinos in supernovae
Naoki Yamamoto
The conventional neutrino transport theory for core-collapse supernovae misses one key property of neutrinos: the left-handedness. The chirality of neutrinos modifies the hydrodyna…
Holographic Floquet states: (I) A strongly coupled Weyl semimetal
Koji Hashimoto, Shunichiro Kinoshita, Keiju Murata +1
Floquet states can be realized in quantum systems driven by continuous time-periodic perturbations. It is known that a state known as the Floquet Weyl semimetal can be realized whe…
Pure Gaussian states from quantum harmonic oscillator chains with a single local dissipative process
Shan Ma, Matthew J. Woolley, Ian R. Petersen +1
We study the preparation of entangled pure Gaussian states via reservoir engineering. In particular, we consider a chain consisting of quantum harmonic oscillators wh…
Fermi/non-Fermi mixing in SU() Kondo effect
Taro Kimura, Sho Ozaki
We apply conformal field theory analysis to the -channel SU() Kondo system, and find a peculiar behavior in the cases , which we call Fermi/non-Fermi mixing: The l…
Meissner effect and a stringlike interaction
Chandrasekhar Chatterjee, Ishita Dutta Choudhury, Amitabha Lahiri
We find that a recently proposed interaction involving the vorticity current of electrons, which radiatively induces a photon mass in 3+1 dimensions in the low-energy effective the…
Flavor structure, Higgs boson mass and dark matter in supersymmetric model with vector-like generations
Tetsutaro Higaki, Michinobu Nishida, Naoyuki Takeda
We study a supersymmetric model in which the Higgs mass, the muon anomalous magnetic moment and the dark matter are simultaneously explained with extra vector-like generation multi…
Inflation from periodic extra dimensions
Tetsutaro Higaki, Yoshiyuki Tatsuta
We discuss a realization of a small field inflation based on string inspired supergravities. In theories accompanying extra dimensions, compactification of them with small radii is…
Pseudogap phenomena near the BKT transition of a two-dimensional ultracold Fermi gas in the crossover region
