1. 21. An investigation of the radiation chemistry of a hydrocarbon system and simulation of ESR spectra of triplet state molecules

   Författare :Ola Claesson; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Radiation chemistry; isotope effects; energy transfer; selective straction; spectrum simulation;

   Sammanfattning : This thesis can be divided into two parts.The aim of the studies described in the first part of the thesis isto make clear the dominating processes in the selective decorrpositionof certain solutes that follow low-terrperature radiolysis of crystalline hydrocarbons.1. LÄS MER

3. 22. Hybrid Superconductor/Ferromagnet junctions with a strongly ferromagnetic barrier

   Författare :Olena Kapran; Vladimir Krasnov; Thilo Bauch; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Superconductivity; Josephson junctions; planar Josephson junctions; micro nanoscale fabrication; micromagnetic state; in-situ characterization technique; fysik; Physics;

   Sammanfattning : The spin-triplet superconducting state, predicted in superconductor /ferromagnet heterostructures remains one of the most exotic states of nature. It is expected that the triplet state can be switched on/off by changing the relative orientation of magnetization in multilayer Josephson spin-valve structures. LÄS MER

4. 23. Synthesis and development of compounds for nonlinear absorption of light

   Författare :Tomas Kindahl; Bertil Eliasson; Sascha Ott; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Platinum acetylide; nonlinear absorption; optical power limiting; oxazole; quantum chemistry calculation; quantum chemical calculation; triplet absorption; organisk kemi; Organic Chemistry; fysikalisk kemi; Physical Chemistry; Quantum Chemistry; kvantkemi;

   Sammanfattning : High-intensity light — for instance that from a laser — can be destructive, not only to the human eye, but also to equipment such as imaging sensors and optical communication devices. Therefore, effective protection against such light is desirable. LÄS MER

5. 24. Quantum Optics with Propagating Microwaves in Superconducting Circuits

   Författare :Io Chun Hoi; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; transmon; second-order correlation function; qubit; microwave photons; photon router; superconducting artificial atom; Autler-Townes splitting; quantum network; SQUID; superconducting circuits; cross-Kerr effect; antibunching; Mollow triplet; Josephson junction; quantum optics;

   Sammanfattning : We address recent advances in quantum optics with propagating microwavesin superconducting circuits. This research field exploits on the fact that the coupling between a superconducting artificial atom and propagating microwave photons in a one-dimensional (1D) open transmission line can be made strong enough to observe quantum effects, without using any cavity to confine the microwave photons.

7. 25. Concepts and biomedical applications of excitation-modulated transient state monitoring of fluorescence emitters

   Författare :Baris Demirbay; Jerker Widengren; Yves Mely; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biological and Biomedical Physics; Biologisk och biomedicinsk fysik;

   Sammanfattning : Fluorescence methods have developed very strongly in the last decade, allowing single- molecule detection sensitivity, high specificity, high time- and spatial resolution, as well as high readout speeds. Together, this makes fluorescencea very central readout modality for biomolecular and cellular studies. LÄS MER
