Ultrafast Hidden Spin Polarization Dynamics of Bright and Dark Excitons in 2H-WSe
Mauro Fanciulli, David Bresteau, Jérome Gaudin +9
We performed spin-, time- and angle-resolved extreme ultraviolet photoemission spectroscopy (STARPES) of excitons prepared by photoexcitation of inversion-symmetric 2H-WSe with…
Conservation of a Half-Integer Angular Momentum in Nonlinear Optics with a Polarization Möbius Strip
Martin Luttmann, Mekha Vimal, Matthieu Guer +5
Symmetries and conservation laws of energy, linear momentum and angular momentum play a central role in physics, in particular in nonlinear optics. Recently, light fields with non…
Phase-resolved attosecond near-threshold photoionization of molecular nitrogen
S. Haessler, B. Fabre, J. Higuet +10
We photoionize nitrogen molecules with a train of extreme ultraviolet attosecond pulses together with a weak infrared field. We measure the phase of the two-color two-photon ioniza…
Observation of magnetic helicoidal dichroism with extreme ultraviolet light vortices
Mauro Fanciulli, Matteo Pancaldi, Emanuele Pedersoli +17
We report on the experimental evidence of magnetic helicoidal dichroism, observed in the interaction of an extreme ultraviolet vortex beam carrying orbital angular momentum with a…
In situ sub-50 attosecond active stabilization of the delay between infrared and extreme ultraviolet light pulses
Martin Luttmann, David Bresteau, Jean-François Hergott +2
The blooming of attosecond science (1 as = s) has raised the need to exquisitely control the delay between two ultrashort light pulses, one of them being intense and in…
Electromagnetic theory of Helicoidal Dichroism in reflection from magnetic structures
Mauro Fanciulli, David Bresteau, Mekha Vimal +3
We present the classical electromagnetic theory framework of reflection of a light beam carrying Orbital Angular Momentum (OAM) by an in-plane magnetic structure with generic symme…
