1. 1. Representations of Three-Body Interactions In Physics

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

   Författare :Joel Johansen; [2023]
   Nyckelord :Three-Body Interactions; Two-Body Interactions; Physics and Astronomy;

   Sammanfattning : The thesis explores an already developed symmetry adapted representation of a two-body interaction with the main goal of extending the method to also include three-body interactions. The method considers a space of shifted one dimensional Gaussian particle densities which are used, together with their corresponding Hartree potentials, to define the respective collective subspaces in which the interactions are expanded.

3. 2. Black Hole Dynamics in Stellar Clusters

   Master-uppsats, Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Astronomi - Genomgår omorganisation

   Författare :Markus Strickert; [2022]
   Nyckelord :Black Holes; Globular Clusters; Dynamics; Intermediate-mass black holes; Simulations; Physics and Astronomy;

   Sammanfattning : Star clusters can harbour many exotic objects, including black holes (BHs), X-ray binaries and blue straggler stars. In dense stellar environments like globular clusters (GCs), two-body relaxation drives their dynamical evolution, where gravitational interactions between stars strive to equalize their kinetic energy in the cluster.

4. 3. Stars Eating Planets

   Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

   Författare :John Wimarsson; [2020]
   Nyckelord :Earth and planetary astrophysics; planetary dynamics; planet-planet scattering; planet consumption; Physics and Astronomy;

   Sammanfattning : In a phase of instability during the dynamical evolution of some multiple exoplanetary systems, exchange of angular momentum and/or energy through gravitational interactions between planets will lead to alterations of their orbital properties. In some cases, planetary orbits end up crossing, which leads to close encounters between two planets. LÄS MER

5. 4. Collective behaviour in suspensions of pushers and pullers

   Master-uppsats, Lunds universitet/Biofysikalisk kemi

   Författare :Shan Anjum; [2019]
   Nyckelord :biophysics; active matter; collective motion; microswimmers; biohydrodynamics; non-equilibrium physics; low reynolds number physics; biophysical chemistry; biofysikalisk kemi; Physics and Astronomy; Chemistry; Technology and Engineering;

   Sammanfattning : Microswimmer is a term that denotes small selfpropelling agents, such as bacteria, algea or artificial robots. Depending on the flow field they set up they can be categorized into two classes: pushers (e.g. E. LÄS MER
