Relativistic stability of positronium atoms in a linearly polarized high frequency super-intense laser field

Relativistic stability of positronium atoms in a linearly polarized high frequency super-intense laser field

Utilizing the relativistically corrected Krammers-Henneberger (KH) potential in the high frequency Floquet theory (HFFT), the ground state of the positronium (Ps) atom in a linearly polarized high frequency super-intense laser field is investigated numerically. It is reported that the relativistic e...
