  1. 1. On the use of the uniform complex scaling-method for studying time-dependent systems

    Author : Jakob Bengtsson; Eva Lindroth; Nimrod Moiseyev; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; kemisk fysik; Chemical Physics;

    Abstract : During the last few decades, laser technology has gone through a series of revolutionary improvements. With light pulses in the sub-femtosecond regime now experimentally available, an explicit time-dependent Hamilton operator is indispensable for a proper theoretical description of the interactions of atoms with such pulses.

  2. 2. Resonances, dissipation and decoherence in exotic and artificial atoms

    Author : Mikhail Genkin; Eva Lindroth; Lars Bojer Madsen; Stockholms universitet; []
    Keywords : quantum dissipation; quantum decoherence; open quantum systems; resonances; fysik; Physics;

    Abstract : There are several reasons why exotic and artificial atoms attract the interest of different scientific communities.In exotic atoms, matter and antimatter can coexist for surprisingly long times. Thus, they present a unique natural laboratory for high precision antimatter studies. READ MORE

  3. 3. Theoretical studies of collisions involving the H2 reaction complex

    Author : Johan Hörnquist; Åsa Larson; Eva Lindroth; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; fysik;

    Abstract : In this thesis, collisions involving the H2 reaction complex are studied theoretically and the processes considered are mutual neutralization, double charge transfer, associative ionization, dissociative recombination and resonant ion-pair formation. These processes are examples of reactions that involve several excited states and where the Born-Oppenheimer approximation is not applicable. READ MORE

  4. 4. Non-linear Spectroscopy of Conical Intersections

    Author : Deependra Jadoun; Markus Kowalewski; Eva Lindroth; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; kemisk fysik; Chemical Physics;

    Abstract : Conical Intersections (CIs) in a molecule originate from the breakdown of the Born-Oppenheimer approximation when electronic states come close in energy. Ultrafast non-radiative decay channels open up in the vicinity of a CI, thus funneling a molecule from one electronic state to another. READ MORE

  5. 5. Relativistic light-matter interaction

    Author : Tor Kjellsson Lindblom; Eva Lindroth; Bernard Piraux; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Time-dependent Dirac equation; Beyond dipole effects; Relativistic effects; High-Intensity laser-matter interaction; teoretisk fysik; Theoretical Physics;

    Abstract : During the past decades, the development of laser technology has produced pulses with increasingly higher peak intensities. These can now be made such that their strength rivals, and even exceeds, the atomic potential at the typical distance of an electron from the nucleus. READ MORE
