Quantum Hall effect in multilayered massless Dirac fermion systems with tilted cones
N. Tajima, T. Yamauchi, T. Yamaguchi +6
We report the first observation of Shubnikov-de Haas (SdH) oscillations and quantized Hall resistance in the multilayered massless Dirac fermion system -(BEDT-TTF)I with…
Multiple length and time scales of dynamic heterogeneities in model glass-forming liquids: A systematic analysis of multi-point and multi-time correlations
Kang Kim, Shinji Saito
We report an extensive and systematic investigation of the multi-point and multi-time correlation functions to reveal the spatio-temporal structures of dynamic heterogeneities in g…
Temperature Dependence of Highly Excited Exciton Polaritons in Semiconductor Microcavities
Tomoyuki Horikiri, Yasuhiro Matsuo, Yutaka Shikano +4
Observations of polariton condensation in semiconductor microcavities suggest that polaritons can be exploited as a novel type of laser with low input-power requirements. The low-e…
Infrared and Terahertz Spectroscopy of Strongly Correlated Electron Systems under Extreme Conditions
Shin-ichi Kimura, Hidekazu Okamura
Owing to its high brilliance, infrared and terahertz synchrotron radiation (IR/THz-SR) has emerged as a powerful tool for spectroscopy under extreme (i.e., technically more difficu…
Strongly hybridized electronic structure of YbAl2: An angle-resolved photoemission study
M. Matsunami, T. Hajiri, H. Miyazaki +2
We report the electronic structure of a prototypical valence fluctuation system, YbAl2, using angle-resolved photoemission spectroscopy. The observed band dispersions and Fermi sur…
Novel Pauli-paramagnetic quantum phase in a Mott insulator
D. Watanabe, M. Yamashita, S. Tonegawa +9
In Mott insulators, the strong electron-electron Coulomb repulsion prevents metallicity and charge excitations are gapped. In dimensions greater than one, their spins are usually o…
Anisotropic optical conductivity of the putative Kondo insulator CeRuSn
V. Guritanu, P. Wissgott, T. Weig +11
Kondo insulators and in particular their non-cubic representatives have remained poorly understood. Here we report on the development of an anisotropic energy pseudogap in the tetr…
Extracting joint weak values from two-dimensional spatial displacements
Hirokazu Kobayashi, Graciana Puentes, Yutaka Shikano
The joint weak value is a counterfactual quantity related to quantum correlations and quantum dynamics, which can be retrieved via weak measurements, as initiated by Aharonov and c…
Nitrogen-Functionalized Graphene Nanoflakes (GNFs:N): Tunable Photoluminescence and Electronic Structures
J. W. Chiou, Sekhar C. Ray, S. I. Peng +22
This study investigates the strong photoluminescence (PL) and X-ray excited optical luminescence observed in nitrogen-functionalized 2D graphene nanoflakes (GNFs:N), which arise fr…
Hybridized electronic states in potassium-doped picene probed by soft x-ray spectroscopies
Hiroyuki Yamane, Nobuhiro Kosugi
The electronic structure of the unoccupied and occupied states of potassium (K)-doped and undoped picene crystalline films has been investigated by using the element-selective and…
Probing a non-biaxial behavior of infinitely thin hard platelets
Hitomi Nomura, Tomonori Koda, Akihiro Nishioka +1
We give a criterion to test a non-biaxial behavior of infinitely thin hard platelets of symmetry based upon the components of three order parameter tensors. We investigate…
Amino-acid-dependent main-chain torsion-energy terms for protein systems
Yoshitake Sakae, Yuko Okamoto
Many commonly used force fields for protein systems such as AMBER, CHARMM, GROMACS, OPLS, and ECEPP have amino-acid-independent force-field parameters of main-chain torsion-energy…
Photoemission Evidence for Valence Fluctuations and Kondo Resonance in YbAl2
M. Matsunami, A. Chainani, M. Taguchi +9
We use hard x-ray photoemission spectroscopy (HAXPES) to investigate the electronic structure of YbAl2, for which the Yb valence has not been consistently reported to date. The bul…
Optical study of archetypical valence-fluctuating Eu-systems
V. Guritanu, S. Seiro, J. Sichelschmidt +5
We have investigated the optical conductivity of the prominent valence fluctuating compounds EuIr2Si2 and EuNi2P2 in the infrared energy range to get new insights into the electron…
Existence of Heavy Fermions in the Antiferromagnetic Phase of CeIn3
Takuya Iizuka, Takafumi Mizuno, Byeong Hun Min +2
We report the pressure-dependent optical conductivity spectra of a heavy fermion (HF) compound CeIn3 below the Neel temperature of 10 K to investigate the existence of the HF state…
Optimal Probe Wavefunction of Weak-Value Amplification
Yuki Susa, Yutaka Shikano, Akio Hosoya
The weak measurement proposed by Aharonov and his colleagues extracts information of a physical quantity of the system by the post selection as the shifts of the argument of the pr…
