Disorder-sensitive superconductivity in the iron silicide LuFeSi studied by the Lu-site substitutions
T. Watanabe, H. Sasame, H. Okuyama +2
We studied effect of non-magnetic and magnetic impurities on superconductivity in LuFeSi by small amount substitution of the Lu site, which investigated structural, mag…
Slow-roll k-essence
Takeshi Chiba, Sourish Dutta, Robert J. Scherrer
We derive slow-roll conditions for thawing k-essence with a separable Lagrangian . We examine the evolution of the equation of state parameter, , as a function…
Successive phase transitions under high pressure in FeTe0.92
Hironari Okada, Hiroyuki Takahashi, Yoshikazu Mizuguchi +2
We performed magnetization and electrical resistivity measurements under high pressures of up to 19 GPa for FeTe0.92. The compound shows an anomaly in magnetization and resistivity…
Quantum anomalies and some recent developments
Kazuo Fujikawa
Some of the developments related to quantum anomalies and path integrals during the past 10 years are briefly discussed. The covered subjects include the issues related to the loca…
Multigraded rings, diagonal subalgebras, and rational singularities
Kazuhiko Kurano, Ei-ichi Sato, Anurag K. Singh +1
We study the properties of F-rationality and F-regularity in multigraded rings and their diagonal subalgebras. The main focus is on diagonal subalgebras of bigraded rings: these co…
