  1. 1. Feasibility Study of X-ray Free Electron Lasers in Fourth Generation Storage Rings

    Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen; Lunds universitet/MAX IV-laboratoriet

    Författare :Jordis Hansen; [2023]
    Nyckelord :XFEL; Storage Ring; Synchrotron Radiation; Physics and Astronomy;

    Sammanfattning : This thesis studies the feasibility of a cavity based X-ray free electron laser in a fourth generation storage ring. The cavity design allows for modulation of the electron beam over several passes through the undulator. Simulations based on the PETRA IV facility are done to create the photon flux spectrum of a light pulse produced by an undulator. LÄS MER

  3. 2. Is the Expression of Hemolysin Co-regulated Protein (Hcp) Associated with Serum Resistance in Aggregatibacter aphrophilus?

    Master-uppsats, Umeå universitet/Tandläkarutbildning

    Författare :Clara Settlin; Selva Hot; [2023]
    Nyckelord :Aggregatibacter aphrophilus; hcp; T6SS; serum resistance;

    Sammanfattning : Abstract  Aggregatibacter aphrophilus, a Gram negative bacterium, found in the oral cavity, causing cerebral abscesses and infective endocarditis, has been shown to be serum resistant in previous studies. Bacterial secretion systems are important for bacteria as they transfer virulence factors into other bacteria or host cells as an attack. A. LÄS MER

  4. 3. Time-dependent light-matter coupling and quantum dynamics

    Kandidat-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Författare :Daniel Elgbro; [2023]
    Nyckelord :light-matter interaction; Rabi oscillations; quantum dynamics; optical cavity; qubit; coupled qubit; coupling strength; time-dependent coupling; dynamical qubits; entanglement; concurrence; qubit state manipulation; Jaynes-Cummings; Tavis-Cummings; Physics and Astronomy;

    Sammanfattning : In this thesis, two quantum dynamical system’s of one and two qubits coupled to a field mode confined in an optical cavity have been studied. Within the Jaynes- and Tavis- Cummings model, the dynamics of the corresponding light-matter interaction was defined in terms of the system’s coupling constants. LÄS MER

  5. 4. Modeling of optical microresonator frequency combs

    Uppsats för yrkesexamina på avancerad nivå, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Michael Ekström; [2022]
    Nyckelord :Optical frequency combs; Nonlinear optics; Temporal cavity solitons;

    Sammanfattning : An optical frequency comb is a structure of equidistant, coherent spectral components which can be thought of as a large array of individual phase-locked laser sources. Their utilization in precision spectroscopy garnering part of the 2005 Nobel prize, optical frequency combs constitute a relatively novel technology with a large number of potential and actual applications.

  7. 5. Prototype Instrumentation for Frequency Domain – Functional Near Infrared Spectroscopy

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Rohit Rathnam Nareshkumar; [2022]
    Nyckelord :Neurofeedback; Frequency domain fNIRS; vertical-cavity surface-emitting laser; silicon photomultiplier;

    Sammanfattning : Frequency domain functional near infrared spectroscopy (FD-fNIRS) is a tissue optical measurement technique used to measure absolute haemoglobin concentrations in brain tissue. This work is intended to be the first step in the development of a wearable, low-cost FD-fNIRS device for neurofeedback applications. LÄS MER
