Comment on "Individual external dose monitoring of all citizens of Date City by passive dosimeter 5 to 51 months after the Fukushima NPP accident (series): II"
Shin-ichi Kurokawa, Yoh Tanimoto, Yutaka Hamaoka +3
This Letter to the Editor points out several inconsistencies found in the paper written by Makoto Miyazaki and Ryugo Hayano published as J. Radiol. Prot. 37(2017) 623-634. This Let…
A study on correlation effects in two dimensional topological insulators
Y. Tada, R. Peters, M. Oshikawa +3
We investigate correlation effects in two dimensional topological insulators (TI). In the first part, we discuss finite size effects for interacting systems of different sizes in a…
Elementary excitations and specific heat in quantum sine-Gordon spin chain KCuGaF6
I. Umegaki, T. Ono, H. Tanaka +2
Elementary excitations of an S = 1/2 antiferromagnetic Heisenberg chain KCuGaF6 were investigated through specific heat and electron spin resonance (ESR) measurements. In this comp…
Effective charge of a deconfined slave particle: Comment on ``Confinement of Slave Particles in U(1) Gauge Theories of Strongly Interacting Electrons''
Masaki Oshikawa
I reexamine the Nayak's criticism [Phys. Rev. Lett. 85, 178 (2000); 86, 943 (2001).] on the U(1) gauge theory approach to the strongly correlated systems. Contrary to his conclusio…
Characterization of a Quasi-One Dimensional Spin-1/2 Magnet which is Gapless and Paramagnetic for g mu_B H <= J and k_B T << J
P. R. Hammar, M. B. Stone, Daniel H. Reich +5
High field mangetization, field-dependent specific heat measurements, and zero field inelastic magnetic neutron scattering have been used to explore the magnetic properties of copp…
A novel intermediate phase in S=2 antiferromagnetic chains with uniaxial anisotropy
M. Oshikawa, M. Yamanaka, S. Miyashita
We study ground state properties of the quantum antiferromagnetic chain with a uniaxially anisotropic Hamiltonian: b…
