Multiplexing Free-Space Channels using Twisted Light [PDF]
, 2015 We experimentally demonstrate an interferometric protocol for multiplexing optical states of light, with potential to become a standard element in free-space communication schemes that utilize light endowed with orbital angular momentum (OAM).

Lipschitz-free Spaces on Finite Metric Spaces [PDF]
Canadian Journal of Mathematics, 2019 AbstractMain results of the paper are as follows:(1) For any finite metric space$M$the Lipschitz-free space on$M$contains a large well-complemented subspace that is close to$\ell _{1}^{n}$.(2) Lipschitz-free spaces on large classes of recursively defined sequences of graphs are not uniformly isomorphic to$\ell _{1}^{n}$of the corresponding dimensions ...

Vortex instability in turbulent free-space propagation [PDF]
, 2018 The spatial structuring of optical fields is integral within many next generation optical metrology and communication techniques. A verifiable physical model of the propagation of these optical fields in a turbulent environment is important for ...

Overview of the Earthcare L2 Lidar Retrieval Chain
EPJ Web of Conferences, 2016 In this paper an introduction to the planned L2 retrieval algorithms for the Earth Clouds and Radiation Explorer (EarthCARE) lidar ATLID is given. The ATLID instrument is a high spectral resolution lidar which will provide independent retrievals of ...

Journal of Marine Science and Engineering, 2019 The effect of the maritime environment on radio frequency (RF) propagation is not well understood. In this work, we study the propagation of ad hoc 2.4 GHz and 5 GHz wireless local area network systems typically used for near-shore operation of unmanned ...

Free Subspaces of Free Locally Convex Spaces [PDF]
Journal of Function Spaces, 2018 IfXandYare Tychonoff spaces, letL(X)andL(Y)be the free locally convex space overXandY, respectively. For generalXandY, the question of whetherL(X)can be embedded as a topological vector subspace ofL(Y)is difficult. The best results in the literature are that ifL(X)can be embedded as a topological vector subspace ofL(I), whereI=[0,1], thenXis a ...

Coherent Quantum Engineering of Free-Space Laser Cooling [PDF]
, 2006 We perform a quantitative analysis of the cooling dynamics of three-level atomic systems interacting with two distinct lasers. Employing sparse-matrix techniques, we find numerical solutions to the fully quantized master equation in steady state.

The Rigged Hilbert Space of the Free Hamiltonian [PDF]
, 2003 We explicitly construct the Rigged Hilbert Space (RHS) of the free Hamiltonian $H_0$. The construction of the RHS of $H_0$ provides yet another opportunity to see that when continuous spectrum is present, the solutions of the Schrodinger equation lie in ...
