1. Symmetry Breaking Ordering Constraints
Sammanfattning : Many problems in business, industry, and academia can be modelled as constraint programs consisting of matrices of decision variables. Such “matrix models” often have symmetry. In particular, they often have row and column symmetry as the rows and columns can freely be permuted without affecting the satisfiability of assignments. LÄS MER
2. Circle maps with symmetry-breaking perturbations
Sammanfattning : .... LÄS MER
3. Isospin symmetry breaking in the A = 51 mirror nuclei
Sammanfattning : [abstract missing].... LÄS MER
4. Effective Field Theory for QCD-like Theories and Constraints on the Two Higgs Doublet Model
Sammanfattning : This thesis includes two topics.The first three papers is the major part of this thesis, which is about higher order calculations in the effective field theories of three QCD-like theories. These three QCD-like theories are distinguished by having quarks in a complex, real or pseudo-real representation of gauge group. LÄS MER
5. Ultrafast spin dynamics at the nanoscale : using coherent X-ray and terahertz radiation
Sammanfattning : The field of ultrafast magnetism is driven by the growing need for faster and more efficient magnetic data storage, which comprises the vast majority of the digital information worldwide. However, after more than two decades of intense research, the understanding of the fundamental physical processes governing the transfer of angular momentum necessary for magnetic switching, is still lacking, partially hampered by the appropriate experimental tools.
