1. 1. Fano Resonances in Time-Dependent Wells

   University essay from Uppsala universitet/Materialteori

   Author : Anton Gregefalk; [2023]
   Keywords : Fano resonance; Floquet scattering; Pumped shot-noise; Linear band tilt; Quadratic band touching; Time periodic Hamiltonian;

   Abstract : Floquet’s theorem, a temporal analogue of Bloch’s theorem, is used for studying a time-dependent potential. With applications in cold atoms on optical lattices, quantum dots and more, there is a growing interest in Floquet engineering exotic materials and phases. READ MORE

3. 2. A VVER1000 primary side model in Apros

   University essay from KTH/Fysik

   Author : Karl-Edvin Strand; [2023]
   Keywords : Apros; VVER1000; PWR; Modelling; HPIS; Boron acid; Apros; VVER1000; PWR; Modellering; HPIS; Borsyra;

   Abstract : Nuclear power plants generate electricity by means of splitting atoms. The basic safety requirements and objectives are to protect the people, society, and the environment from radiological accidents, limit harmful effects of ionizing radiation during operation and take all reasonable practical steps to prevent radiological accidents.

4. 3. Structure-based design of new antiviral substances against the Venezuelan equine encephalitis virus

   University essay from Lunds universitet/Tillämpad biokemi; Lunds universitet/Beräkningskemi

   Author : Elin Öberg; [2022]
   Keywords : x-ray crystallography; protein crystallization; Venezuelan equine encephalitis virus; structure-based drug design; applied biochemistry; Technology and Engineering;

   Abstract : The Venezuelan equine encephalitis virus (VEEV) is a highly infectious alphavirus responsible for severe outbreaks and epidemics in the Americas. The nonstructural protein 2 (nsP2) cysteine protease plays a fundamental role in the VEEV replication process, and is therefore, an attractive drug target for structure-based drug design using x-ray crystallography.

5. 4. Microscopic and Macroscopic Samples of Atoms in Superposition States Studied by Attosecond Pulses

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

   Author : Axel Stenquist; [2021]
   Keywords : Mathematical physics; Theoretical physics; Atomic physics; Attosecond physics; Ultra-fast physics; Numerical simulations; Microscopic; Mesoscopic; Macroscopic; Superposition; Light matter interaction; Quantum mechanics; Electromagnetism; Semiclassical; Attosecond transient absorption spectroscopy; ATAS; Förster resonance; FRET; Two-atom model; Inter-atomic interaction; Dipole-dipole interaction; Many-atom model; Collective coherent effects; Time-dependent configuration-interaction singles; TDCIS; Physics and Astronomy;

   Abstract : In the present thesis, the interaction between atoms in superposition states and attosecond pulses is studied from the microscopic to the macroscopic regime. Using a semi-classical framework, three different models have been explored in order to investigate attosecond light--matter interaction processes. READ MORE

6. 5. A Fabry–Pérot Cavity for Rare-Earth-Ion-Doped Nanocrystals

   University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Author : Andre Nüsslein; [2019]
   Keywords : Quantum Computer; Rear Earth Ions; Cavity; Laser; Cavity Quantum Electrodynamics; QED; Solidworks; Physics and Astronomy;

   Abstract : This thesis work contributes to the effort of detecting single rare earth ions doped into crystals, an operation crucial for the development of rare earth quantum computer hardware. Doping crystals with rare earth elements, their trivalent ions substitute some of the crystal’s original bonds. READ MORE
