Journal ArticleDOI
Collective modes of the axi-planar phase
TL;DR: In this paper, the collective mode frequencies of the axi-planar phase of a uniform spin triplet p-wave superfluid were derived using a time dependent Ginzburg-Landau model.
Journal ArticleDOI

TL;DR: In this article, an artificially atomic-scale ordered superlattice alloy system was proposed to pursue high-ZT materials, where the electronic structure can be modified from semimetal, through zero-gap, to semiconductor by changing the super lattice period and sublayer thicknesses using electrical resistivity, thermopower and magneto-transport measurements.
Journal ArticleDOI
Nonreciprocal spin-wave propagation in YIG/GGG: a limit on the DMI parameter
Proceedings Article
Nonlinear optical properties of potassium titanyl phosphate thin film deposited by UV laser ablation
H. Zhou,P. M. Lundquist,D. N. Hahn,John B Ketterson,George K. Wong,F. Xong,Robert P. H. Chang +6 more
TL;DR: In this article, the second-order nonlinear optical susceptibility of a thin KTiOPO/sub 4/ film was measured on a sapphire (100) substrate by laser ablating a target made by polycrystalline KTP ceramic powder.
Proceedings ArticleDOI
Nonlinear optical properties of metal nitride thin films
TL;DR: In this paper, the authors present experimental studies of gallium nitride and aluminum nitride thin films, including fabrication and optical characterization, which indicate that they may have potential for cost effective development of nonlinear optical waveguide devices.
