1. 1. Investigation of a newrepresentation of spin

   University essay from Uppsala universitet/Materialteori

   Author : Minna Palmgren Thun; [2023]
   Keywords : Material theory; Spin; Statistical physics; Second quantization; Materialteori; spinn;

   Abstract : The Bose-Hubbard Model, a tight binding model within solid state theory can be solved exactly using a number theoretical approach. From this approach, in the two sited Bose-Hubbard model, the hopping term in the model takes the form of a Pauli x matrix. The hopping term can be interpreted as a two energy level system or a dimer with k+1 particles. READ MORE

3. 2. Transversal Construction of Topological Gates on Multiqubit Quantum Codes

   University essay from Uppsala universitet/Materialteori

   Author : Sheila Chauwinoir; [2022]
   Keywords : entanglement; local SU 2 evolution; topological phase factors; topological gates; transversal gates; multiqubit quantum codes; Hopf fibration;

   Abstract : We study the possibility of constructing quantum gates using topological phases, which originate from local SU(2) evolution of entangled multiqubit systems. For this purpose, logical codewords using two-, three- and nine-qubit entangled states are defined and possible implementations of topological gates on these codes, are examined. READ MORE

4. 3. Gravitational Waves in Bimetric Gravity

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Erik Schildt; [2022]
   Keywords : ;

   Abstract : Understanding the cause of the accelerated expansion of the Universe is one of the most pressing issues in modern cosmology. An alternative to the LambdaCDM-model is bimetric gravity which is an extension of Einstein's theory of general relativity. READ MORE

5. 4. On the (1/2,1/2) Representation of the Lorentz Group and the Discrete CPT Symmetries

   University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Author : Nikolaj Skog Pirinen; [2021]
   Keywords : The Lorentz Group; Group Theory; Quantum Field Theory; CPT; Symmetry; Spinors; Representation Theory; Physics and Astronomy;

   Abstract : This thesis derives the explicit form of the elements of the (1/2,1/2) representation of the Lorentz group, by actually performing a direct product of the chiral (1/2,0)- and (0,1/2)-representations. The Lorentz transformations of fourvectors are thereafter recovered from this direct-product representation, allowing the derivation of a transformation matrix between the fourvector- and direct product basis.

6. 5. The living in a place for the dead - an exploration of place as assemblage

   University essay from Lunds universitet/Institutionen för kulturgeografi och ekonomisk geografi

   Author : Emma Jonsson; [2021]
   Keywords : assemblage; affect; place; urban cemetery; urban planning; Malmö; Social Sciences;

   Abstract : This thesis investigates how place can be understood through assemblage theory and what that implies for the understanding of human relation to place. The framework has been widely used outside and within human geography, at a few instances related to place. READ MORE
