1. 1. Deep Neural Networks as SurrogateModels for Fuel Performance Codes

   University essay from Uppsala universitet/Tillämpad kärnfysik

   Author : Wenhan Zhou; [2023]
   Keywords : Transuranus; AI; Nuclear Fuel Rods;

   Abstract : The core component of a nuclear power plant is the reactor and the fuel rods that supply it with fission fuel. Efficient and safe energy extraction is thus highly dependent on the reactor design and the conditions of the fuel rods. To anticipate high-quality operation and potential risks in advance, one must perform simulations on the fuel rods. READ MORE

3. 2. Investigating the response of terrestrial evapotranspiration to droughts in Africa : A combined remote sensing and modeling approach

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Yang Foo; [2023]
   Keywords : earth observation; terrestrial evapotranspiration; drought; vegetation-climate interactions;

   Abstract : Climate change is posing a significant threat to terrestrial ecosystems worldwide, in part due to the more frequent occurrence of extreme climatic events such as droughts. While the importance of drought impacts on vegetation has been widely recognized, the time-dependent characteristics of drought-induced response remain insufficiently understood. READ MORE

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

   University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

   Author : Daniel Elgbro; [2023]
   Keywords : 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;

   Abstract : 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. READ MORE

5. 4. Implementing two-qubit gates along paths on the Schmidt sphere

   University essay from Uppsala universitet/Materialteori

   Author : Max Johansson Saarijärvi; [2022]
   Keywords : Quantum; Physics; Quantum physics; Quantum information; Quantum computers; Quantum computation; qubit; quantum gate; geometric quantum computation; GQC; quantum decoherence; Kvantfysik; Kvantdatorer; Kvantinformation; kvant; kvantberäkning; kvantgrind;

   Abstract : Qubits (quantum bits) are what runs quantum computers, like a bit in classical computers. Quantum gates are used to operate on qubits in order to change their states. As such they are what ”programmes” a quantum computer. READ MORE

6. 5. Gap properties of helical edge states in two-dimensional topological insulators with time-dependent magnetic impurities

   University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

   Author : Simon Wozny; [2020]
   Keywords : topological insulators; edge states; impurities; density of states; Green s function; Floquet; Physics and Astronomy;

   Abstract : The quantum mechanical equivalent of the classical Hall effect can lead to interesting results in solid state physics. A similar effect, that has received attention in recent years, occurs when large spin-orbit coupling is present in a material, the so-called quantum-spin Hall effect. READ MORE
