The envelope Hamiltonian for electron interaction with ultrashort pulses
Koudai Toyota, Ulf Saalmann, Jan M. Rost
For ultrashort VUV pulses with a pulse length comparable to the orbital time of the bound electrons they couple to we propose a simplified envelope Hamiltonian. It is based on the…
Prevailing features of X-ray induced molecular electron spectra revealed with fullerenes
Abraham Camacho Garibay, Ulf Saalmann, Jan M. Rost
Intense X-ray photo-absorption from short and intense pulses by a molecule triggers complicated electron and subsequently ion dynamics leading to photo-electron spectra which are d…
Characterizing weak chaos in nonintegrable Hamiltonian systems: the fundamental role of stickiness and initial conditions
Cesar Manchein, Marcus W. Beims, Jan M. Rost
Weak chaos in high-dimensional conservative systems can be characterized through sticky effect induced by invariant structures on chaotic trajectories. Suitable quantities for this…
