Fractionalization in an Easy-axis Kagome Antiferromagnet

, 2001
We study an antiferromagnetic spin-1/2 model with up to third nearest-neighbor couplings on the Kagome lattice in the easy-axis limit, and show that its low-energy dynamics are governed by a four site XY ring exchange Hamiltonian. Simple ``vortex pairing'

Application of Hexagonal Reference Maps in Gravity-Assisted Inertial Navigation

Journal of Marine Science and Engineering
High-resolution and high-precision marine gravity reference maps are core prerequisites for the practical application of gravity-assisted inertial navigation algorithms, and their accuracy directly determines the performance of the navigation system.

Comparative evaluation of peri-implant tissues in patients wearing mandibular overdenture with different implant platforms

Journal of Indian Society of Periodontology, 2017
Background: The poor hygiene of peri-implant tissues causes inflammation at tissue-implant interface, which may impair the rehabilitation success. The aim of this study was to evaluate the influence of external hexagon and Morse taper implants on peri ...

'Hexagon-type' photonic crystal slabs based on SOI [PDF]

, 2002
In this paper we discuss the design of a novel category of photonic crystal slabs (PCS) and as an example, we consider structures based on SOI wafers. Fabrication issues related to lithographic accuracy are addressed, too.

Tile Count in the Interior of Regular 2n-gons Dissected by Diagonals Parallel to Sides [PDF]

, 2009
The regular 2n-gon (square, hexagon, octagon, ...) is subdivided into smaller polygons (tiles) by the subset of diagonals which run parallel to any of the 2n sides.
