Field-free molecular orientation by a multicolor laser field
We theoretically study the field-free molecular orientation by a multicolor laser field with a superposition of the fundamental wave and its harmonics. It is shown that the molecular orientation will be up to a maximum value pumped by the four-color laser field at the same laser intensity, and the molecular orientation direction and its degree can be controlled by varying the carrier-envelope p...
متن کاملTwo-state wave packet for strong field-free molecular orientation.
We demonstrate strong laser-field-free orientation of absolute-ground-state carbonyl sulfide molecules. The molecules are oriented by the combination of a 485-ps-long nonresonant laser pulse and a weak static electric field. The edges of the laser pulse create a coherent superposition of two rotational states resulting in revivals of strong transient molecular orientation after the laser pulse....

متن کاملTransition between mechanisms of laser-induced field-free molecular orientation.
The transition between two distinct mechanisms for the laser-induced field-free orientation of CO molecules is observed via measurements of orientation revival times and subsequent comparison to theoretical calculations. In the first mechanism, which we find responsible for the orientation of CO up to peak intensities of 8 × 10(13) W/cm(2), the molecules are impulsively oriented through the hyp...
متن کاملFree energy of QCD at high temperature.
Effective-field-theory methods are used to separate the free energy for a nonabelian gauge theory at high temperature T into the contributions from the momentum scales T , gT , and g2T , where g is the coupling constant at the scale 2πT . The effects of the scale T enter through the coefficients in the effective lagrangian for the 3-dimensional effective theory obtained by dimensional reduction...
