Active Negative Index Metamaterial Electron Beam Optics
2012/5/17
A novel active negative index metamaterial that derives its gain from an electron beam is intro- duced. The metamaterial consists of a stack of equidistant parallel metal plates perforated by a period...
Surface plasmon modes of a single silver nanorod: an electron energy loss study
plasmon modes silver nanorod an electron energy loss study
2011/9/5
We present an electron energy loss study using energy filtered TEM of spatially resolved surface plasmon excitations on a silver nanorod of aspect ratio 14.2 resting on a 30 nm thick silicon nitride m...
Dynamic of rescattering-electron wave packets in strong and short-wavelength laser fields: Roles of Coulomb potential and excited states
scattering-electron wave packets in strong short-wavelength laser fields Coulomb potential excited states
2014/5/28
We investigate the high-order harmonic generation of atoms and molecules exposed in strong and shortwavelength (shorter than 800 nm) laser fields. Our simulations show that the electronic rescattering...
Optically induced spin polarisation of the NV- centre in diamond: role of electron-vibration interaction
Optically induced spin polarisation NV- centre in diamond: role electron-vibration interaction
2010/11/22
The novel aspect of the centre (NV−) in diamond is the high degree of spin polarisation achieved through optical illumination. In this paper it is shown that the spin polarisation occurs as a co...
An accelerated particle sees the Minkowski vacuum as thermally excited, and the particle
moves stochastically due to an interaction with the thermal bath. This interaction fluctuates
the particle’s ...
Elastic electron-deuteron scattering and two-body current operators in the Light-Front Hamiltonian Dynamics
Elastic electron-deuteron scattering two-body current operators Light-Front Hamiltonian Dynamics
2011/1/6
The electromagnetic properties of the deuteron are investigated within a Light-Front Hamilto-
nian Dynamics framework, with a current operator that contains both one-body and two-body
contributions....
Contribution of interband effects caused by long-wavelength transverse optical phonons to electron-phonon coupling in doped polar insulators
Contribution of interband effects electron-phonon coupling doped polar insulators
2010/11/22
We estimate the contribution of the long-wavelength el–TO–ph interaction and discuss the effect it has on electron pairing in doped polar systems like SrTiO3 and PbTe. The analytical and numerical res...
Harmonic operation of high gain harmonic generation free electron laser
harmonic operation HGHG FEL
2009/8/14
In high gain harmonic generation (HGHG) free electron laser (FEL), with the right choice of parameters of the modulator undulator, the dispersive section and the seed laser, one may make the spatial b...

Monte Carlo Simulation as an Auxiliary Tool for Electron Beam Quality Specification for Intra-Operative Radiotherapy
an Auxiliary Tool Electron Beam Quality Intra-Operative Radiotherapy
2010/10/15
Intra-operative radiotherapy (IORT) using electron beams has demonstrated to be a good alternative as part of the breast-conserving surgery. Besides, as the computer processing capacity has been incre...
