1. 1. Robust non-Abelian geometric phases on three-qubit spin codes

   University essay from Uppsala universitet/Materialteori

   Author : Parham Azish; [2024]
   Keywords : Quantum information theory; Holonomic quantum computing; non-abelian systems;

   Abstract : Quantum holonomies are non-Abelian Geometric Phases predominantly observed in adiabatic, non-adiabatic, or measurement-based quantum evolutions. Their significance lies in their potential utility within quantum computing due to their robustness against noise throughout the parameter path. READ MORE

3. 2. Representations of Three-Body Interactions In Physics

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

   Author : Joel Johansen; [2023]
   Keywords : Three-Body Interactions; Two-Body Interactions; Physics and Astronomy;

   Abstract : 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.

4. 3. Black Hole Dynamics in Stellar Clusters

   University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Astronomi - Genomgår omorganisation

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

   Abstract : 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.

5. 4. Finite temperature effects on decay rates in the real-time formalism

   University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Author : Torbjörn Lundberg; [2020]
   Keywords : finite; temperature; effect; decay; rate; real; imaginary; time; formalism; real-time; imaginary-time; two-body; neutral; pseudoscalar; scalar; charge; spin-1 2; fermions; thermal; quantum; field; theory; equilibrium; Physics and Astronomy;

   Abstract : This thesis work presents thermal decay rates for several reactions calculated within the framework of the real-time formalism. Processes considered are those of a neutral (pseudo)scalar decaying into two distinct (pseudo)scalars or into a fermion-antifermion pair. READ MORE

6. 5. A Non-Relativistic Model of Tetraquarks

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Per Lundhammar; [2020]
   Keywords : ;

   Abstract : In this thesis, a non-relativistic model of tetraquark in a diquark-antidiquark configuration is investigated. Using a variation of the Cornell potential, the Schrödinger equation is solved numerically, and the four-body problem of the tetraquark is separated into to three two-body problems. READ MORE
