Detecting the topological charge of vortex beams using an annular triangle aperture
Vortex beam Topological charge Annular triangle aperture
2013/7/3
The Fraunhofer diffraction pattern of a vortex beam by an annular triangle aperture is analyzed theoretically and experimentally. It is found that the pattern of the far-field diffraction intensity di...
Probing the magnetic ground state of the molecular Dysprosium triangle
magnetic ground state molecular Dysprosium triangle
2010/11/18
We present zero eld muon spin lattice relaxation measurements of a Dysprosium triangle molecular magnet. The local magnetic elds sensed by the implanted muons indicate the coexistence of static and ...
AC square-wave, sawtooth-wave, and triangle-wave fields driven adiabatic quantum pumps in nanowire structures
AC square-wave sawtooth-wave triangle-wave fields driven adiabatic quantum pumps
2010/11/18
A dc current can be pumped through a nanostructure by two out-of-phase ac driving fields.
In this approach, we explore the pumped current properties driven by square-wave, sawtoothwave,
and triangle...
Efficient Triangle Counting in Large Graphs via Degree-based Vertex Partitioning
Efficient Triangle Counting Graphs Degree-based Vertex Partitioning
2010/11/17
The number of triangles is a computationally expensive graph statistic which is frequently used in complex network analysis (e.g., transitivity ratio), in various random graph models (e.g., exponenti...
