1. 1. Computational modelling of photosynthetic excitons coupled to a microcavity

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

   Author : Ilmari Turunen; [2022]
   Keywords : Cavity QED; LH2; Chlorophyll; Exciton; Polariton; Transition dipole moment; Absorbance; Physics and Astronomy; Chemistry; Biology and Life Sciences;

   Abstract : Cavity quantum electrodynamics (QED) is a theory that is used for describing the interaction between matter and cavity modes. Not until relatively recently, cavity QED has been extended to the study of photosynthetic light-harvesting complexes (LHCs). READ MORE

3. 2. Global Cultures – Critical Zone Observatories of Everyday Objects : (A Global Environmental History of Yogurt)

   University essay from Uppsala universitet/Institutionen för arkeologi och antik historia

   Author : Leni Charbonneau; [2022]
   Keywords : yogurt; biofilm; critical zone observatory; microbiopolitics; probiotic; microbial biodiversity; new materialism; OOO;

   Abstract : This study turns to what is for many an everyday item – yogurt – as a critical zone observatory, a synergistic, place-based laboratory which aims to integrate heterogenous representations of planetary phenomena as they are registered at a common surface. Yogurt has an impressive cultural endurance largely derived from its prominence in various paradigms of health. READ MORE

4. 3. Nonlinear mode coupling and parametric amplification with superconducting kinetic inductance

   University essay from KTH/Tillämpad fysik

   Author : Daniele Lopriore; [2022]
   Keywords : Quantum technology; microwave engineering; nanofabrication; parametric amplifiers; multimode entanglement; kinetic inductance; Kvantteknologi; mikrovågsteknik; nanotillverkning; parametriska förstärkare; multimodentrassling; kinetisk induktans;

   Abstract : We investigate the resonant characteristics of superconducting meandering nanowires to design a nonlinear kinetic inductance traveling-wave parametric amplifier. The devices are patterned out of 15 nm thick NbTiN films. They consist of a coplanar waveguide, that shrinks into 100 nm wide meandering nanowires. READ MORE

5. 4. HVDC transformer core resonance calculation

   University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Author : Axel Thorstrand; [2021]
   Keywords : HVDC; High Voltage Direct Current; Transformer core; Natural frequencies; Energy method-based equation; HVDC; Högspänning likström; Transformatorkärna; Naturliga frekvenser; Energimetod;

   Abstract : Transformers emit a characteristic humming noise due to magnetostriction which is the continuous change in dimensions during magnetization. The noise is amplified if the induced frequencies match the core’s natural frequencies, consequently avoiding geometries that create resonance is critical in order to fulfill customer sound level requirements.

6. 5. First Principle Calculations & Inelastic Neutron Scattering on the Single-Crystalline Superconductor LaPt2Si2

   University essay from KTH/Materialvetenskap

   Author : Mazza Federico; [2020]
   Keywords : Superconductivity; LaPt2Si2; Inelastic Neutron Scattering; Charge Density Wave; Band Structure Calculations; DFT; SNIC; J-PARC; Supraledning; LaPt2Si2; neutronspridning; neutronspektroskopi; Bandberäkningar; DFT; J-PARC;

   Abstract : This work presents a comprehensive study on single crystalline LaPt2Si2, in which superconductivity and a charge density wave (CDW) coexist. The usage of density functional theory (DFT) modeling and Inelastic Neutron Scattering has been the primary form of investigation, in order to determine all the characteristic features of the sample taken under consideration.
