1. 1. Single Photon Sources and Single Quantum System enabled Communication

   Författare :Muhammad Alley Hameedi; Mohamed Bourennane; Nicolas Brunner; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantum information; quantum optics; quantum communication; single photon sources; fysik; Physics;

   Sammanfattning : Quantum information is a highly interesting and fast emerging field that involves processing information encoded into quantum systems and their subsequent use in various information tasks. The use of quantum resources such as superposition and entanglement have shown to enhance information processing capabilities beyond classical means in a number of communication, information and computation tasks.

3. 2. Live Single Cell Imaging and Analysis Using Microfluidic Devices

   Författare :Mohammad Ali Khorshidi; Helene Andersson-Svahn; Håkan Jönsson; Carolina Wählby; Johan Elf; KTH; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Single cell analysis; time-lapse fluorescence imaging; automated image analysis; microwell; droplet microfluidics; NK cells; single cell tracking; migration behavior analysis; cell-cell interaction; optical microscopy; image analysis; image processing; microfluidics; immune cells; tracking; counting; morphology analysis;

   Sammanfattning : Today many cell biological techniques study large cell populations where an average estimate of individual cells’ behavior is observed. On the other hand, single cell analysis is required for studying functional heterogeneities between cells within populations. LÄS MER

4. 3. Single-Photon Events in the DELPHI Experiment

   Författare :Elisabeth Falk; Partikel- och kärnfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; kvantfältteori; Elementarpartikelfysik; quantum field theory; DELPHI; STIC; LEP; single-photon events; PS; off-energy electrons; silicon-strip detector; coherent noise; emittance; Elementary particle physics; fast wire scanner; High energy interactions; cosmic rays; Kosmisk strålning; högenergi; Fysicumarkivet A:1998:Falk Harris;

   Sammanfattning : A series of studies pertaining to the STIC calorimeter at the DELPHI experiment at LEP is presented, and a new generation of fast wire scanners for emittance measurements at PS is described. The STIC studies are centered around a single-photon analysis, in which the reaction e+ e- -> gamma + invisible particles was studied at center-of-mass energies of 161, 172 and 183 GeV. LÄS MER

5. 4. Giant Dipole Resonances as Probes of Local Environment in Molecules, Clusters and Solidsl

   Författare :Jarek Luberek; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; single center; photoionization; fullerene; coupled channels; LDA; giant dipole resonance; embedded; time-dependent local density;

   Sammanfattning : In this thesis, I study effects of the local environment on the giant dipole resonances (GDR) in lanthanides and actinides. The effects of embedding in jellium, bonding in small molecules and incorporation into different fullerene systems are studied. LÄS MER

7. 5. Ultrafast Structural Changes in a Bacterial Photosynthetic Reaction Center probed with XFEL Radiation

   Författare :Robert Dods; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Photosynthesis; Reaction Center; Time-resolved crystallography; XFEL; membrane protein;

   Sammanfattning : Photosynthesis is the process by which plants and many species of bacteria convert energy from sunlight into chemical energy used to power their metabolism. As these plants and bacteria are eaten, the chemical energy moves up the food chain and thus photosynthesis provides fuel for almost all life on Earth. LÄS MER
