The Infrared behavior of SU(3) Nf=12 gauge theory -about the existence of conformal fixed point-
Kenji Ogawa, Tatsumi Aoyama, Hiroaki Ikeda +8
Incorporated with twisted boundary condition, Polyakov loop correlators can give a definition of the renormalized coupling. We employ this scheme for the step scaling method (with…
Metamagnetic Behavior and Kondo Breakdown in Heavy-Fermion CeFePO
S. Kitagawa, H. Ikeda, Y. Nakai +5
We report that nonmagnetic heavy-fermion (HF) iron oxypnictide CeFePO with two-dimensional XY-type anisotropy shows a metamagnetic behavior at the metamagnetic field H_M \simeq 4 T…
Extremely strong coupling superconductivity in artificial two-dimensional Kondo lattices
Y. Mizukami, H. Shishido, T. Shibauchi +8
When interacting electrons are confined to low-dimensions, the electron-electron correlation effect is enhanced dramatically, which often drives the system into exhibiting behavior…
Conformal fixed point of SU(3) gauge theory with 12 fundamental fermions
Tatsumi Aoyama, Hiroaki Ikeda, Masafumi Kurachi +7
We study the infrared properties of SU(3) gauge theory coupled to 12 massless Dirac fermions in the fundamental representation. The renormalized running coupling constant is calcul…
Fermi-Suface Evolution by Transition-metal Substitution in the Iron-based Superconductor LaFeAsO
S. Konbu, K. Nakamura, H. Ikeda +1
We study how Co- and Ni-substitution affect the electronic structure of the iron-based superconductor, LaFeAsO. We perform {\it ab initio} supercell calculations and unfold the fir…
Rotational Symmetry Breaking in the Hidden-Order Phase of URu2Si2
R. Okazaki, T. Shibauchi, H. J. Shi +6
A second-order phase transition is characterized by spontaneous symmetry breaking. The nature of the broken symmetry in the so-called "hidden order" phase transition in the heavy f…
Nodeless vs nodal order parameters in LiFeAs and LiFeP superconductors
K. Hashimoto, S. Kasahara, R. Katsumata +7
High-precision measurements of magnetic penetration depth in clean single crystals of LiFeAs and LiFeP superconductors reveal contrasting low-energy quasiparticle excitations.…
Nodal gap structure of BaFe_2(As_{1-x}P_x)_2 from angle-resolved thermal conductivity in a magnetic field
M. Yamashita, Y. Senshu, T. Shibauchi +8
The structure of the superconducting order parameter in the iron-pnictide superconductor BaFe(AsP) (\,K) with line nodes is studied by the angle-r…
