Mn-doping induced ferromagnetism and enhanced superconductivity in Bi_4-x Mn_x O_4 S_3 (0.075 < = x < = 0.15)

Posted by klaurent Caltech

Kavli Affiliate: N. C. Yeh | First 5 Authors: Zhenjie Feng, Xunqing Yin, Yiming Cao, Xianglian Peng, Tian Gao | Summary: We demonstrate that Mn-doping in the layered sulfides Bi_4O_4S_3 leads to stable Bi_4-x Mn_x O_4 S_3 compounds that exhibit both long-range ferromagnetism and enhanced superconductivity for 0.075 < = x < = 0.15, with […]

Manifest Duality for Partially Massless Higher Spins

Posted by Chicago

Kavli Affiliate: Austin Joyce | First 5 Authors: Kurt Hinterbichler, Austin Joyce, , , | Summary: In four dimensions, partially massless fields of all spins and depths possess a duality invariance akin to electric-magnetic duality. We construct metric-like gauge invariant curvature tensors for partially massless fields of all integer spins and depths, and show how […]
