PARABOLIC AND HYPERBOLIC SCREW MOTION SURFACES IN ℍ2×ℝ [PDF]
Journal of the Australian Mathematical Society, 2008 AbstractIn this paper we find many families in the product space ℍ2×ℝ of complete embedded, simply connected, minimal and surfaces with constant mean curvature H such that |H|≤1/2. We study complete surfaces invariant either by parabolic or by hyperbolic screw motions. We study the notion of isometric associate immersions.

Van der Waals thin films of WTe2 for natural hyperbolic plasmonic surfaces [PDF]
Nature Communications, 2020 A hyperbolic plasmonic surface supports highly directional propagating polaritons with extremely large density of states. Such plasmon polaritons have been realized in artificially structured metasurfaces.

, 2002 A cubic polyhedron is a polyhedral surface whose edges are exactly all the edges of the cubic lattice. Every such polyhedron is a discrete minimal surface, and it appears that many (but not all) of them can be relaxed to smooth minimal surfaces (under an

On the Problem of Reducing the Equations of Rigid Body Dynamics in Hyperbolic Space
Вестник Пермского университета. Математика. Механика. Информатика, 2023 An affine transformation of the space of velocities of the system of equations of motion of an absolutely rigid body is given, moving relative to the center of inertia in a hyperbolic space of constant negative curvature.

Imaging of buried objects from experimental backscattering time dependent measurements using a globally convergent inverse algorithm [PDF]
, 2014 We consider the problem of imaging of objects buried under the ground using backscattering experimental time dependent measurements generated by a single point source or one incident plane wave.

THE LOGARITHMIC SPIRAL AND ITS SPHERICAL COUNTERPART
Journal of Industrial Design and Engineering Graphics, 2020 Logarithmic spirals are isogonal trajectories of pencils of lines. From a series of geometric consequences, we pick out a few which are relevant for kinematics: When a logarithmic spiral rolls on a line, its asymptotic point traces a straight line. Hence,

Giant Spin Seebeck Effect through an Interface Organic Semiconductor [PDF]
, 2019 Interfacing an organic semiconductor C60 with a non-magnetic metallic thin film (Cu or Pt) has created a novel heterostructure that is ferromagnetic at ambient temperature, while its interface with a magnetic metal (Fe or Co) can tune the anisotropic ...

The transfer matrix: a geometrical perspective [PDF]
, 2012 We present a comprehensive and self-contained discussion of the use of the transfer matrix to study propagation in one-dimensional lossless systems, including a variety of examples, such as superlattices, photonic crystals, and optical resonators. In all
