Influence of higher-order Kerr effect on conical emission from laser filaments in gases
higher-order Kerr effect ultrashort laser filaments
2011/8/31
We numerically investigate the conical emission (CE) from ultrashort laser filaments, both considering and disregarding the higher-order Kerr effect (HOKE). While the consideration of HOKE has almost ...
Hawking radiation from ultrashort laser pulse filaments
Hawking radiation ultrashort laser pulse filaments
2010/10/27
Event horizons of astrophysical black holes and gravitational analogues have been predicted to
excite the quantum vacuum and give rise to the emission of quanta, known as Hawking radiation.
We exper...
Swarms of insects and flocks of birds are examples of natural systems in which individual components act independently, yet together display complex collective motion. Scientists have extensively mode...
