23Na and 87Rb are the first two atoms to be Bose-Einstein condensed in 1995.To date,they continue to be two of the most popular atomic species in the research of quantum gases.
In attosecond science,investigations of field-induced ionization processes with attosecond temporal resolution have attracted a lot of attention.In a recent experiment by Shafir et al.[1],the ionizati
High order harmonic generation(HHG)is an important nonlinear effect when atoms and molecules are irradiated by intense laser fields.They can be used to synthesize ultrashort pulses that allow one to o
When exposed to intense laser field,atoms and molecules can absorb many more photons than necessary for ionization and lead to a series of evenly spaced peaks in photoelectron kinetic energy spectra,w
