    We study the p-wave holographic superconductor for AdS black holes with planar event horizon topology for a particular Lovelock gravity, in which the action is characterized by a self-interacting scalar field nonminimally coupled to the gravity theory which is labeled by an integer kk. As the Lovelock theory of gravity is the most general metric theory of gravity based on the fundamental assumptions of general relativity, it is a desirable theory to describe the higher dimensional spacetime geometry. The present work is devoted to studying the properties of the p-wave holographic superconductor by including a Maxwell field which nonminimally couples to a complex vector field in a higher dimensional background metric. In the probe limit, we find that the critical temperature decreases with the increase of the index kk of the background black hole metric, which shows that a larger kk makes it harder for the condensation to form. We also observe that the index kk affects the conductivity and the gap frequency of the holographic superconductors.Comment: 14 pages, 6 figure

    In the title coupound, [Mn(C9H6O4)(C12H8N2)]n, the MnII ion is coordinated by two N atoms [Mn—N = 2.273 (3) and 2.305 (2) Å] from a 1,10-phenanthroline ligand and four O atoms [Mn—O = 2.112 (2)–2.343 (3) Å] from three 5-methyl­isophthalate (mip) ligands in a distorted octa­hedral geometry. Each mip dianion acts as a tetra­dentate ligand connecting three Mn ions. The crystal packing exhibits π–π inter­actions [3.599 (2)–3.755 (2) Å] between the centroids of the six-membered rings of neighbouring 1,10-phenanthroline ligands
