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

   Författare :Daniel Larsson Persson; [2023]
   Nyckelord :Circuit Quantum Electrodynamics; Open Quantum Systems; Gaussian States; Two-Mode Two-Photon Jaynes-Cummings Model; Jaynes-Cummings Model; Lyapunov Equation; Phase-Space Description; Duan Criterion; Entanglement; Light-Matter Interaction; Mean Field; Double Quantum Dot; Harmonic Oscillator; Two-Mode Squeezing; Symplectic Form; GKSL Equation; Lindblad Equation; Physics and Astronomy;

   Sammanfattning : Entanglement is a fundamental aspect of quantum computation and quantum information processes. In this work, we analyse the entanglement of two microwave resonators when connected to a semiconductor double quantum dot. LÄS MER

3. 2. Mathematical modeling and analysis of hot carrier solar cells

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

   Författare :Benjamin van Dijk; [2023]
   Nyckelord :solar cell; nanowires; hot carrier; nanowire; analysis; mathematical model; trends; fermi function; reservoirs; Physics and Astronomy;

   Sammanfattning : This thesis focuses on the analysis of a mathematical model of a nanowire based hot carrier solar cell. The relevance of the topic comes from the energy crisis society is facing today. Firstly, we discuss the basic principle of hot carrier solar cells and discuss several energy loss factors. LÄS MER

4. 3. Feldetektering i återgångkablar

   Kandidat-uppsats, Umeå universitet/Institutionen för tillämpad fysik och elektronik

   Författare :Erik Asp; [2021]
   Nyckelord :Feldetektering;

   Sammanfattning : The purpose of ths report is to shed light on the problems surrounding error detection in returncables, specifically in connection with tunnels. In Sweden, among other things, has chosen to usea BT system with a suction transformer and a dedicated return conductor to reduce interferencesuch as occurs on telecommunications and signal cables along the track.

7. 5. Combining the GW Approximation with the Hubbard I Approximation for strongly correlated materials

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

   Författare :Torsten Strunck; [2019]
   Nyckelord :GWA; GW Approximation; HIA; Hubbard I Approximation; Hubbard-I Approximation; Hubbard model; DMFT; Dynamical Mean Field Theory; strongly correlated materials; electron correlations; solid state physics; Physics and Astronomy;

   Sammanfattning : In this thesis, the GW approximation (GWA, Green's function G times screened interaction W) and the Hubbard I approximation (HIA) are combined in a non-self-consistent one-shot calculation to determine the electronic structure of a one-dimensional strongly-correlated model. The scheme was chosen to incorporate both screening effects through the GWA and strong on-site correlations through the atomic HIA. LÄS MER
