DOI: 10.1016/j.optcom.2017.02.063
Abstract: Abstract The spatiotemporal dynamics of femtosecond filamentation were investigated numerically to evaluate various intensity distributions of zero-order Mathieu beams without the phase alteration for adjacent lobes. The side filaments are formed due to constructive interferences… read more here.

DOI: 10.1016/j.optcom.2018.12.039
Abstract: Abstract An intense laser would suffer nonlinear effects during its propagation in plasma, which greatly affects the illumination uniformities of laser beams in a hohlraum for ignition. Based on the theory of the relativistic and… read more here.

DOI: 10.1088/1361-6587/abe695
Abstract: A semi-Lagrangian relativistic Vlasov–Maxwell solver is used to describe the non-linear momentum transfer between electron beams, which is driven by spontaneous fluctuations in the oblique filamentation instability (a type of Weibel mode) in two-dimensional plasmas.… read more here.

DOI: 10.1128/mbio.02135-18
Abstract: For the ubiquitous environmental pathogen Cryptococcus neoformans, the morphological transition from yeast to filament confers resistance to natural predators like soil amoeba and is an integral differentiation event to produce infectious spores. Interestingly, filamentation is… read more here.
