1. 11. Quantum Computing in Nuclear Physics

   Master-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

   Författare :Luca Bernecker; [2022]
   Nyckelord :quantum computing; nuclear physics; qubits; theoretical physics; Physics and Astronomy;

   Sammanfattning : In this thesis, we investigate many–body systems using simulations of quan- tum computers. Quantum computing is a computational paradigm based on qubits which are defined in a Hilbert space instead of the familiar binary bits. LÄS MER

3. 12. Colliding Galaxies in a (Nut)Shell

   Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Fysiska institutionen

   Författare :Jonathan Petersson; [2022]
   Nyckelord :shell galaxies; simulations; starbursts; quenching; mergers; Physics and Astronomy;

   Sammanfattning : Galaxy interactions and mergers are natural recurring events in the current cosmological paradigm, events that often coincide with starbursts and enhanced star formation activity. To understand why that is, one can use idealised (non-cosmological) merger simulations, which provide freedom to recreate specific tidally distorted galaxies, and analysis of the time evolution and underlying physics of the star formation activity at a high spatial resolution.

4. 13. On The Run: How Fast Runaway Stars Can Escape From Their Home Cluster?

   Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

   Författare :Anna-Maria Söderman; [2022]
   Nyckelord :star cluster; runaway stars; velocity distribution; Physics and Astronomy;

   Sammanfattning : Galaxies contain a wide variety of star clusters with different properties. Each cluster is a possible source of runaway stars, which can be progenitors of supernovae in other parts of the galaxy than their home cluster. Considering runaway stars in galaxy simulations has shown to increase the galactic feedback. LÄS MER

5. 14. Information Flow and Local Observables in Many Body Localized Systems

   Master-uppsats, KTH/Fysik

   Författare :Daniel Niemi; [2022]
   Nyckelord :Theoretical physics; many body localization; localization; aubry-andré; aubry-andrei; condensed matter; quantum matter; Teroretisk fysik; mångpartikellokalisering; lokalisering; aubry-andré; aubry-andrei; kondenserad materia; kvantmateria;

   Sammanfattning : Disordered quantum many-body systems exhibiting the many-body localization (MBL) phenomenon evade the fate of thermalization due to the existence of an extensively large set of quasi-local integrals of motion (l-bits). Due to the size of the Hilbert space of many-body systems, it is hard to compute the time evolution of many-body systems generally, which hinders our understanding of the MBL phenomenon. LÄS MER

7. 15. Stellar Encounters at the Galactic Centre

   Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

   Författare :Roberts Fisers; [2022]
   Nyckelord :Galaxy; encounter; SPH; NSC; Physics and Astronomy;

   Sammanfattning : Using methods of smoothed particle hydrodynamics (SPH) an N -body simulation was set-up to investigate stellar encounters between a 1 solar-mass main sequence (MS) star, modeled after the Sun, and a 0.6 solar-mass white dwarf (WD). This was done primarily to investigate the assumptions made by Mastrobuono-Battisti et al. LÄS MER
