Superintense laser fields

E. E. Aubanel, J. M. Gauthier, and A. D. Bandrauk, Phys. Rev. A, 48, 2145 (1993). First Prediction of Molecular Stabilization in Intense Laser Fields—Creation of New Molecules in Superintense Laser Fields. 

In high harmonic generation experiments [9], atoms are subjected to superintense laser fields, in which the motions of the driven electrons... 

In this chapter, we discuss some new developments in TDDFT beyond the linear response regime for accurate and efficient nonperturbative treatment of multiphoton dynamics and very-high-order nonlinear optical processes of atomic and molecular systems in intense and superintense laser fields. In Section 2, we briefly describe the time-dependent optimized effective potential (OEP) method and its simplified version, i.e., the time-dependent Krieger-Li-Iafrate (KLI) approximation, along with self-interaction correction (SIC). In Section 3, we present the TDDFT approaches and the time-dependent generalized pseudospectral (TDGPS) methods for the accurate treatment of multiphoton processes in diatomic and triatomic molecules. In Section 4, we describe the Floquet formulation of TDDFT. This is followed by a conclusion in Section 5. Atomic units will be used throughout this chapter. 

Finally, availability of more exact data on the. -nucleus and p.-atom interactions is important in astrophysics, studying substance transformation in the Universe, testing the Standard Model etc. [6, 21,49, 50]]. e-p-Y-nuclear spectroscopy of atoms (molecules) opens new prospects in combining nuclear physics and quantum chemistry (atomic physics). These possibilities are strengthened by quickly developed nuclear quantum optics [19-26]. Superintense lasers (raser or even graser) field may provide a definite measurement of the change in the dynamics of the nuclear processes, including the muon capture (and/or y, P-, a-decay) [18-26,48,50],...
