Magnon Spin Nernst Effect in Antiferromagnets.
We predict that a temperature gradient can induce a magnon-mediated spin Hall response in an antiferromagnet with nontrivial magnon Berry curvature. We develop a linear response theory which gives a general condition for a Hall current to be well defined, even when the thermal Hall response is forbidden by symmetry. We apply our theory to a honeycomb lattice antiferromagnet and discuss a role o...
متن کاملThree-dimensional beta shapes
The Voronoi diagram of a point set has been extensively used in various disciplines ever since it was first proposed. Its application realms have been even further extended to estimate the shape of point clouds when Edelsbrunner and Mücke introduced the concept of α-shape based on the Delaunay triangulation of a point set. In this paper, we present the theory of β-shape for a set of three-dimen...
متن کاملThree - dimensional Alpha Shapes 1
Frequently, data in scientiic computing is in its abstract form a nite point set in space, and it is sometimes useful or required to compute what one might call the \shape" of the set. For that purpose, this paper introduces the formal notion of the family of-shapes of a nite point set in IR 3. Each shape is a well-deened polytope, derived from the Delaunay triangulation of the point set, with ...
متن کاملSynthesis of Supported Pt Alloy three Dimensional Rhombus Shapes Nanoparticles for Oxygen Reduction Reaction
In this study PtFeCo ternary alloys nanoparticles of three dimentional (3D) rhombus shapes dispersed on graphene nanosheets (PtFeCo/Gr) were successfully prepared and studied as electrocatalysts for oxygen reduction reaction (ORR) in polymer-electrolyte fuel cells. A combination of analytical techniques including powder X-ray diffraction, X-ray photoelectron spectra, inductively coupled plasma-...
متن کاملTwo-magnon instabilities and other surprises in magnetized quantum antiferromagnets
The ordered states of a planar antiferromagnet with a triangular lattice are investigated in the presence of a magnetic field. The spin wave free energy is taken into account and proves to be important for determining the properties of the system. The phase diagram is constructed. It contains four different phases with rigorous long-range order. Three of them are characterised by different conf...
