Polarization-Dependent Three-Dimensional Angle-Resolved Photoemission Spectroscopy of BaFeCoAs
Tetsuya Hajiri, Takahiro Ito, Masaharu Matsunami +3
We performed polarization- and photon-energy-dependent angle-resolved photoemission spectroscopy of a slightly overdoped iron pnictide superconductor, BaFeCoAs$_{2}…
Stereographical visualization of a polarization state using weak measurements with an optical-vortex beam
Hirokazu Kobayashi, Koji Nonaka, Yutaka Shikano
We propose a stereographical-visualization scheme for a polarization state by two-dimensional imaging of a weak value with a single setup. The key idea is to employ Laguerre-Gaussi…
Electronic Structure Reconstruction across the Antiferromagnetic Transition in TaFeTe Spin Ladder
M. Xu, Li-Min Wang, R. Peng +19
With angle-resolved photoemission spectroscopy, we studied the electronic structure of TaFeTe, which is a two-leg spin ladder compound with a novel antiferromagnetic g…
I molecule for neutrino mass spectroscopy: ab initio calculation of spectral rate
Motomichi Tashiro, Masahiro Ehara, Susumu Kuma +4
It has recently been argued that atoms and molecules may become good targets of determining neutrino parameters still undetermined, if atomic/molecular process is enhanced by a new…
Dynamic Length Scales in Glass-Forming Liquids: A Inhomogeneous Molecular Dynamics Simulation Approach
Kang Kim, Shinji Saito, Kunimasa Miyazaki +2
In this work we numerically investigate a new method for the characterization of growing length scales associated with spatially heterogeneous dynamics of glass-forming liquids. Th…
Spin-polarized angle-resolved photoelectron spectroscopy of the so-predicted Kondo topological insulator SmB6
Shigemasa Suga, Kazuyuki Sakamoto, Taichi Okuda +13
Undoped and slightly Eu-doped SmB6 show the opening of a gap with decreasing temperature below ~150 K. The spectral shapes near the Fermi level (EF) at 15 K have shown strong incre…
A Strained Organic Field-Effect-Transistor with a Gate-Tunable Superconducting Channel
Hiroshi M. Yamamoto, Masaki Nakano, Masayuki Suda +3
In state-of-the-art silicon devices, mobility of the carrier is enhanced by the lattice strain from the back substrate. Such an extra control of device performance is significant i…
Microscopic mechanism for asymmetric charge distribution in Rashba-type surface states and the origin of the the energy splitting scale
Beomyoung Kim, Panjin Kim, Wonsig Jung +9
Microscopic mechanism for the Rashba-type band splitting is examined in detail. We show how asymmetric charge distribution is formed when local orbital angular momentum (OAM) and c…
From Discrete Time Quantum Walk to Continuous Time Quantum Walk in Limit Distribution
Yutaka Shikano
The discrete time quantum walk defined as a quantum-mechanical analogue of the discrete time random walk have recently been attracted from various and interdisciplinary fields. In…
An ARPES Study of the Electronic Structure of the Quantum Spin Liquid EtMe3Sb[Pd(dmit)2]2
Q. Q. Ge, H. C. Xu, X. P. Shen +10
The electronic structure of a quantum spin liquid compound, EtMe3Sb[Pd(dmit)2]2, has been studied with angle-resolved photoemission spectroscopy, together with two other Pd(dmit)2…
Reply to "Comment on `Optimal probe wave function of weak-value amplification' "
Yuki Susa, Yutaka Shikano, Akio Hosoya
It is pointed out that the "counter example" presented in the Comment is a family of probe wave functions which are increasingly broad as the shift becomes large. Furthermore, the…
Frequency dependence of specific heat in supercooled liquid water and emergence of correlated dynamics
Shinji Saito, Iwao Ohmine, Biman Bagchi
Molecular origin of the well-known specific heat anomaly in supercooled liquid water is investigated here by using extensive computer simulations and theoretical analyses. A rather…
An analytical continuation approach for evaluating emission lineshapes of molecular aggregates and the adequacy of multichromophoric Förster theory
Leonardo Banchi, Gianluca Costagliola, Akihito Ishizaki +1
In large photosynthetic chromophore-protein complexes not all chromophores are coupled strongly, and thus the situation is well described by formation of delocalized states in cert…
Strong Correlation Effects of A-site Ordered Perovskite CaCu3Ti4O12 revealed by Angle-Resolved Photoemission Spectroscopy
H. J. Im, M. Tsunekawa, T. Sakurada +8
We report angle-resolved photoemission spectroscopy (ARPES) results of A-site ordered perovskite CaCuTiO. We have observed the clear band dispersions, which are shif…
Discrete-time quantum walk with feed-forward quantum coin
Yutaka Shikano, Tatsuaki Wada, Junsei Horikawa
Constructing a discrete model like a cellular automaton is a powerful method for understanding various dynamical systems. However, the relationship between the discrete model and i…
Self-Assembled Nanowires with Giant Rashba-Type Band Splitting
Jewook Park, Sung Won Jung, Min-Cherl Jung +3
We investigated Pt-induced nanowires on the Si(110) surface using scanning tunneling microscopy (STM) and angle-resolved photoemission (ARP). High resolution STM images show a well…
Operational derivation of Maxwell-Boltzmann distribution with Maxwell's demon model
Akio Hosoya, Koji Maruyama, Yutaka Shikano
The resolution of the Maxwell's demon paradox linked thermodynamics with information theory through information erasure principle. By considering a demon endowed with a Turing-mach…
