Atomic force microscope (AFM) has been developed at first for topography imaging; in addition, it is used for characterization of mechanical properties. Most researches have been primarily focused on rectangular single-beam probes to make vibration models simple. Recently, the U-shaped AFM probe is employed to determine sample elastic properties and has been developed to heat samples locally. I...

Analytical expressions, in presence of skew quadrupoles errors, have been derived to estimate the betatron coupling contribution to the vertical beam size and emittance [1]. The treatment of the betatron coupling is based on the matrix transport perturbation and related eigen vectors. The advantage of this approach is to be free of the usual resonant approximation and to allows a compact formul...

The thickness and temperature dependences of the interlayer exchange coupling in well-defined molecular beam epitaxy-grown Fe/Si/Fe sandwich structures have been studied. The biquadratic coupling shows a strong temperature dependence in contrast to the bilinear coupling. Both depend exponentially on thickness. These observations can be well understood in the framework of Slonczewski's loose spi...

In order to reach high luminosity, the Future Circular e $$^+$$ $$^-$$ Collider will need very intense beams with small emittances and beta functions in interaction points. This is achieved a large Piwinski angle combined crab waist collision scheme. Under these conditions, luminosity beam–beam tune shifts are strongly influenced by bunch length. On other hand, this machine, beamstrahlung effec...

The simulation of mixed-dimensional couplings poses a variety computational challenges in order to enable accurate modeling and efficient solution problems science, engineering biomedicine. In this contribution, we study bottlenecks the coupled beam/solid systems discuss possible remedies allow large-scale computations applications structural engineering. particular, address questions memory co...

Transparent conductive oxides such as indium tin oxide (ITO) bear the potential to deliver efficient all-optical functionality due their record-breaking optical nonlinearity at epsilon near zero (ENZ) wavelengths. All-optical applications generally involve more than one beam, but, our knowledge, coherent interaction between beams has not previously been discussed in these materials, which have ...

The hollow plasma channel is analyzed as an accelerating structure. The excitation of the channel by an ultra-relativistic beam is analyzed. Coupling to the fundamental and all higher order azimuthal modes of the excited electromagnetic elds is derived. Implications of this work for plasma-based accelerators, including beam loading and beam breakup, are discussed. Small initial transverse displ...
