Measuring the magnetic dipole transition of single nanorods by spectroscopy and Fourier microscopy
R. Chacon, A. Leray, J. Kim +6
Rare-earth doped nanocrystals possess optical transitions with significant either electric or magnetic dipole characters. They are of strong interest for understanding and engineer…
LAGOVirtual: A Collaborative Environment for the Large Aperture GRB Observatory
R. Camacho, R. Chacon, G. Diaz +10
We present the LAGOVirtual Project: an ongoing project to develop platform to collaborate in the Large Aperture GRB Observatory (LAGO). This continental-wide observatory is devised…
Vectorial probing of electric and magnetic transitions in variable optical environments and vice-versa
R. Chacon, A. Leray, J. Kim +6
We use europium doped single crystalline NaYF nanorods for probing the electric and magnetic contributions to the local density of optical states (LDOS). Reciprocically, we det…
Controlling Chaotic transport on Periodic Surfaces
R. Chacon, A. M. Lacasta
We uncover and characterize different chaotic transport scenarios on perfect periodic surfaces by controlling the chaotic dynamics of particles subjected to periodic external force…
Universality in ratchets without spatial asymmetry
R. Chacon
It is demonstrated that to optimally enhance directed transport by symmetry breaking of temporal forces there exists a universal force waveform which allows to deduce universal sca…
Reshaping-induced spatiotemporal chaos in driven, damped sine-Gordon systems
R. Chacon
Spatiotemporal chaos arising from the competition between sine-Gordon-breather and kink-antikink-pair solitons by reshaping an ac force is demonstrated. After introducing soliton c…
A mathematical description of natural shapes in our nonlinear world
R. Chacon
The work presents two examples of simple mathematical formulas which are natural nonlinear modifications (one being a generalization) of Gielis' formula. These formulas involve a c…
