1. 6. Parametrically pumped superconducting circuits

   Författare :Philip Krantz; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; SQUID; circuit quantum electrodynamics; Josephson junction; Superconducting circuits; resonators; parametric oscillators; quantum bit; pumpistor; quantum information;

   Sammanfattning : In this licentiate thesis, I present the design, fabrication, and characterization of superconducting parametric resonators, for use in quantum information processing. These devices are quarter-wavelength coplanar waveguide resonators (~5 GHz), terminated at one end by a non-linear inductance provided by a SQUID (superconducting quantum interference device).

3. 7. Electron-nuclear Dynamics in Nonlinear Optics and X-ray spectroscopy

   Författare :Sergey Polyutov; Faris Gelmukhanov; Patrick Norman; KTH; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Biokemi;

   Sammanfattning : This thesis is devoted to theoretical studies of the role of nuclear vibrations on nonlinear and linear absorption, pulse propagation, and resonant scattering of light. The molecular parameters needed for the simulations are obtained through suitable quantum chemical calculations, which are compared with available experimental data. LÄS MER

4. 8. Tunable superconducting transmissionline resonator for qubit coupling

   Författare :Martin Sandberg; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fast tuning; superconductivity; transmission line; SCB; Josephson inductance.; Frequency tunable resonator; SQUID; CPW; aluminium;

   Sammanfattning : In this licentiate thesis design, fabrication, and measurements of tunable superconducting microwave transmission line resonators are described. The resonators are of quarter wavelength type were the tuning is achieved by changing one of the boundary conditions of the resonator through a tunable impedance. LÄS MER

5. 9. Strong exciton-photon and exciton-exciton coupling and its effects on molecular photophysics

   Författare :Yi Yu; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Strong coupling; triplet transition dynamics; TADFs; aggregate states;

   Sammanfattning : The energy of molecular states and their transition dynamics form the key properties to understand the photophysics of organic molecules. Strong exciton-photon and exciton-exciton couplings enable the possibility to manipulate these properties without changing the chemical structures. This is due to the formation of new energy states.

7. 10. A soft X-ray emission study of the electronic structure of molecules

   Författare :Kerstin Gunnelin; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; molecules; electronic structure; soft x-ray emission spectroscopy; Fysik; Physics; Fysik; fysik; Physics;

   Sammanfattning : The electronic structure of molecules has been studied with soft x-ray emission (SXE)spectroscopy. The parity selection rule for electronic transitions using resonant excitation has been verified for homonuclear diatomic molecules by studying N2 and O2. LÄS MER
