1. Improving Email Security in Organizations : Solutions and Guidelines
University essay from Högskolan Dalarna/Institutionen för information och teknikAbstract : Data breaches from email attacks have been an issue since email was first implemented. Common attack methods like phishing are still a threat to organizations to this very day. That is because it never seems to stop evolving and keeps becoming more and more convincing. READ MORE

2. Beyond the Gross-Pitaevskii Equation: A Perturbative Approach
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Teknisk fysik (CI)Abstract : We propose and implement a beyond Gross-Pitaevskii approach based on Many-Body Perturbation theory (MBPT) for the study of Bose-Einstein Condensate (BECs) ground states. Two partitions of the system Hamiltonian are considered. READ MORE

3. Bose-Einstein Condensate Jets from Different Traps
University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionenAbstract : This thesis presents a numerical study of the emission of jets by a trapped Bose-Einstein Condensate (BEC). The Gross-Pitaevskii equation is used for the simulation of this phenomenon. When the scattering length of a trapped BEC is periodically modulated it emits jets of matter. READ MORE

4. Rotational Properties of Lee-Huang-Yang Bosonic Condensates from One to Two Dimensions
University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionenAbstract : This thesis covers the work of a numerical examination of the rotational properties of a two-component Bose-Einstein condensate (BEC) utilizing the beyond mean-field extended Gross-Pitaevskii equation for a specified set of parameters. These parameters are chosen to cancel the strength of the mean-field interaction, which makes the system predominantly governed by the next order beyond the mean-field Lee-Huang-Yang (LHY) term.

5. Beyond Mean-Field Description of Bose-Einstein Condensate
University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionenAbstract : This thesis work is on the theoretical description of dilute Bose-Einstein condensates (BEC) that are non-uniform, meaning that more than one single-particle state is occupied. This phenomenon is usually called quantum depletion. READ MORE
