  4. 2. Non-linear attosecond physics at 100 eV

    Author : Alexander Muschet; Laszlo Veisz; Piotr Matyba; Per Eng-Johnsson; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; extreme ultraviolet XUV ; non-linear XUV – matter interaction; high-harmonic generation; photoionization; attosecond physics; isolated attosecond pulses; attosecond XUV pump – XUV probe spectroscopy; fysik; Physics;

    Abstract : Non-linear interactions between light and matter have nowadays a broad range of applications. They are used for frequency doubling in simple laser pointers as well as for a variety of purposes in complex laser systems like the one presented in this thesis. READ MORE

  5. 3. Theoretical perspectives on ultrafast and non-linear spectroscopy

    Author : Emil Vinas Boström; Matematisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Non-linear optics; Ultrafast dynamics; Non-equilibrium Green s functions; Density functional theory; Multi-photon absorption; Second harmonic generation; Desorption dynamics; Auger decay; Charge-separation dynamics; Quantum Zeno effect; Fysicumarkivet A:2018:Vinas Boström;

    Abstract : In this thesis we discuss a theoretical description of ultrafast and non-linear spectroscopy. Due to the high intensities and ultrashort pulse durations involved in such experiments, it is necessary to use an explicitly time-dependent formalism. READ MORE

  6. 4. Non-Linear Spatio-Temporal Dynamics of Optical Beams and Pulses in Kerr and Ionizable Media

    Author : Manuel López Quiroga Teixeiro; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; self-focussing; wave-breaking; optical Kerr effect; autowaves; fast adiabatic compression; non-linear modes conversion; non-linear optics; blue-shift; solitons; full wave numerical simulations; optical fibers; ionization non-linearities; pulse compressioni;

    Abstract : The present thesis includes results of several investigations concerning the propagation of optical pulses in optical fibers and spatio-temporal beams in optical Kerr media and ionizable media. Both numerical and analytical methods play an important role in the investigations. READ MORE

  7. 5. 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
