We present the calculation of the probability production of an electron-positron pair in the presence of a strong magnetic field with time-varying strength. The calculation takes into account the presence of a strong, constant and uniform gravitational field in the same direction of the magnetic field. The results show that the presence of the gravitational field in general enhances very much t...

Methods of controlling molecular rotations using linearly polarized femtosecond and picosecond pulses are considered and analyzed theoretically. These laser pulses, typically in the infrared, are highly non-resonant with respect to the electronic degrees of freedom of the molecules and have intensities of ∼ 10 to 10 W/cm. It is shown how these laser pulses can force small linear molecules to al...

We investigate the differential ionization probability of chiral molecules in strong-field regime as a function helicity incident light. To this end, we analyze fourfold bromochlorofluoromethane (CHBrClF) with subsequent fragmentation into four charged fragments and different dissociation channels singly ionized methyloxirane. By resolving for molecular orientation, show that photoion circular ...
