Vers le contrôle de l'alignement et de l'orientation : théorie et expérience
2010
This thesis is about the control and characterisation of the alignment and orientation of molecules by ultra short laser pulses on a theoretical and experimental approach. Alignment corresponds to a symmetric angular distribution of the molecular axis peaked along the laser field axis, whereas orientation provides an asymmetric distribution favouring one spatial direction. Orientation by sudden two-colour (2+1) pulses is studied extensively for the non resonant case and conditions required for achieving significant orientation are explored. A second two-colour scheme, where the second harmonic is in quasi resonance with a vibrational level of the molecule, is also presented and discussed. T…
The emergence and the evolution of the obligatory characteristic of cognitive automatisms
2013
The aim of this thesis is to examine the emergence and the evolution of the obligatory characteristic of cognitive automatisms. To achieve this, we devised a new experimental situation called musical Stroop. The basic arrangement comprises a treble staff with a note in various positions. A name of a note is printed inside the note. For the congruent condition, the note name is congruent with the note position on the staff, whereas in the incongruent condition, note name and position are incongruent. We showed that musicians process the incongruent condition slower than the congruent condition (Study 1). This effect, named Musical Stroop Effect (MSE), is generated by the automaticity of note…
