1. 11. Quantum ring with tangential dipoles

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

   Author : Carmen López Jurado; [2021]
   Keywords : Bose-Einstein condensate; Quantum Droplets; Gross-Pitaevskii equation; Physics and Astronomy;

   Abstract : This Bachelor thesis studies the formation of quantum droplets in a dilute dipolar Bose Einstein Condensate with the initial shape of a torus. The main question to address is how this formation occurs as the magnetic dipole moment of the particles changes orientation with respect to the xy plane. READ MORE

3. 12. Exploring the Gauge Sector of a Composite Two-Higgs Doublet Model

   University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Author : Adam Warnerbring; [2021]
   Keywords : two-Higgs doublet model; composite Higgs model; composite two-Higgs doublet model; Physics and Astronomy;

   Abstract : In this bachelor thesis we investigate the gauge sector of a specific composite two-Higgs doublet model, allowing more freedom for the gauge couplings and compositeness scales. From the underlying parameters we generate model realisations with the correct top mass, Higgs mass and electroweak vacuum expectation value, that satisfy theoretical constraints such as unitarity and perturbativity.

4. 13. Occlusion method to obtain saliency maps for CNN

   University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

   Author : Thomas Eriksson; [2020]
   Keywords : Saliency map; explanatory model; process focussed XAI; MNIST; image classifying CNN.; Physics and Astronomy;

   Abstract : This Bachelor project will study convolutional neural networks created for image classification. Furthermore, it will specifically use an explanatory model for how the network decided a certain classification output. This is to increase the interpretability of the network. READ MORE

5. 14. Motion of a Gaussian Through a 2D Dilute BEC Droplet

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

   Author : Zhanna Kuhrij; [2020]
   Keywords : Bose-Einstein Condensate; BEC; Droplet; Dilute; Liquid; Quantum Mechanics; Fluid Dynamics; Superfluid; Superfluidity; Quantum Fluctuations; LHY-correction; Flow patterns; Gaussian; 2D; Vortices; Gross-Pitaevskii Equation; Physics and Astronomy;

   Abstract : In the last decades, Bose-Einstein Condensates (BECs) have been a research topic of great interest. In 2015, a new type of liquid was found - dilute self-bound BEC droplets that have orders of magnitude lower density than air. These droplets are not predicted by classical van der Waals theory, but are stabilised by quantum fluctuations. READ MORE

6. 15. Electron Assisted Growth of Graphene atop Ir(111) supported Hexagonal Boron Nitride

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

   Author : Lassi Linnala; [2019]
   Keywords : Two-dimensional materials; Two-dimensional heterostructures; Graphene; hexagonal Boron Nitride; STM; LEED; Physics and Astronomy;

   Abstract : Vertical heterostructures between graphene (Gr) and hexagonal boron nitride (hBN) have attracted a great deal of interest, due to their potential applications in the semiconductor industry as new and superior transistor materials. The direct growth of the heterostucture still remains challenging and in this bachelor thesis, I report a novel electron assisted growth technique, which is used to attempt to grow Gr atop hBN atop an Ir(111) single crystal surface.
