1. 1. Ice and wind loads on guyed masts

   Författare :Claes Fahleson; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

   Sammanfattning : Atmospheric icing is a large problem for many structures located in regions with cold climate. Structures as guyed masts and overhead transmission lines and towers are particularly exposed. A 323 meter high guyed TV and radio mast in Arvidsjaur in Northern Sweden was equipped with an extensive data collection system in the winter 1988-89. LÄS MER

3. 2. Development and characterization of damped cubic response functions with application to two-photon absorption

   Författare :Tobias Fahleson; Patrick Norman; Joanna Kauczor; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Molecular response to electromagnetic fields - static or optical - within a framework of perturbation theory diverges close to resonance with molecular transitionen energies, and need work-around solutions for real-valued response functions. This licentiate thesis deals with nonlinear response, with focus being on cubic polarizaibilities, and outlines the underlying mathematics for exact-state and approximatestate, complex-valued response functions applicable to quantum chemical computation.

4. 3. Derivation and application of response functions for nonlinear absorption and dichroisms

   Författare :Tobias Fahleson; Patrick Norman; Daniel Crawford; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Theoretical spectroscopy; cubic response theory; damped response theory; magnetic circular dichroism; linear birefringence; two-photon absorption; TPA; resonant-inelastic x-ray scattering; RIXS; DALTON program; Teoretisk kemi och biologi; Theoretical Chemistry and Biology;

   Sammanfattning : This thesis is titled ’Derivation and application of response functions for nonlinear absorption and dichroisms’ and was written by Tobias Fahleson at the Division of Theoretical Chemistry & Biology at KTH Royal Institute of Technology in Sweden. It explores and expands upon theoretical means of quantifying a number of nonlinear spectroscopies, including two-photon absorption, resonant inelastic x-ray scattering, Jones birefringence, and magnetic circular dichroism.
