Abrupt recovery of Fermi-liquid transport by the c-axis collapse in CaFe2(As1-xPx)2 single crystals
S. Kasahara, T. Shibauchi, Y. Nakai +4
Single crystals of CaFe(AsP) are found to exhibit the tetragonal (T) to collapsed-tetragonal (cT) transition at \,K for . The c-…
Comments on Gaugino Mass and Landscape of Vacua
Yuichiro Nakai, Yutaka Ookouchi
In direct gauge mediation, gaugino masses often vanish at the leading order of supersymmetry breaking. Recently, this phenomenon is understood in connection with the global structu…
Revisiting superparticle spectra in superconformal flavor models
Tatsuo Kobayashi, Yuichiro Nakai, Ryo Takahashi
We study superparticle spectra in the superconformal flavor scenario with non-universal gaugino masses. The non-universality of gaugino masses can lead to the wino-like or higgsino…
Unconventional superconductivity and antiferromagnetic quantum critical behavior in the isovalent-doped BaFe2(As1-xPx)2
Y. Nakai, T. Iye, S. Kitagawa +7
Spin dynamics evolution of BaFe(AsP) was probed as a function of P concentration via P NMR. Our NMR study reveals that two-dimensional antiferromagnetic…
Inflation and Gauge Mediation in Supersymmetric Gauge Theory
Yuichiro Nakai, Manabu Sakai
We propose a simple high-scale inflationary scenario based on a phenomenologically viable model with direct gauge mediation of low-scale supersymmetry breaking. Hybrid inflation is…
Nonlinearly Realized Extended Supergravity
K. -I. Izawa, Y. Nakai, Ryo Takahashi
We provide nonlinear realization of supergravity with an arbitrary number of supersymmetries by means of coset construction. The number of gravitino degrees of freedom counts the n…
