1. 1. The low-lying zeros of L-functions associated to non-Galois cubic fields

   University essay from Göteborgs universitet/Institutionen för matematiska vetenskaper

   Author : Victor Ahlquist; [2023-02-13]
   Keywords : Mathematics; number theory; cubic fields; L-functions; low-lying zeros; onelevel density; two-level density; phase transition.;

   Abstract : We study the low-lying zeros of Artin L-functions associated to non-Galois cubic number fields through their one- and two-level densities. In particular, we find new precise estimates for the two-level density with a power-saving error term. READ MORE

3. 2. Exploring New Physics Through Collider and Gravitational Wave Measurements with Artificial Neural Networks: the Case Study of QCD-like Technicolor

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Author : Ashar Ahmed Kamal; [2023]
   Keywords : Artificial Neural Networks; ANN; Beyond the Standard Model; BSM; parameter space scan; Physics and Astronomy;

   Abstract : With physicists actively exploring Beyond the Standard Model (BSM) theories that may fill in the gaps of the Standard Model (SM), a fundamental question arises: which parameters hold physical significance? In this thesis, we present our initial progress towards the development of a model-independent artificial intelligence framework designed for conducting parameter space scans in BSM scenarios. Our framework incorporates several publicly available high-energy physics packages, namely SPheno, HiggsBounds, HiggsSignals, and CosmoTransitions. READ MORE

4. 3. Phase Transitions in the Two-Higgs-Doublet Model with a Softly-Broken Z2 Symmetry

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Author : Filip Gustavsson; [2023]
   Keywords : Particle Physics; Beyond Standard Model; Two-Higgs Doublet Model; 2HDM; Electroweak Phase Transitions; Strong First-order Phase Transition; Dimensional Reduction; CP-conserving; Softly broken Z2-symmetry; Physics and Astronomy;

   Abstract : The two-Higgs-doublet model (2HDM) is an extension to the Standard Model which adds a second Higgs doublet. This extension provides freedom within the model, in comparison to the Standard Model, which makes it possible to study strong electroweak phase transitions. READ MORE

5. 4. On The Side of the Forest Owner: : A Discourse Analysis of the Swedish Reception of the EU ForestStrategy for 2030

   University essay from Umeå universitet/Statsvetenskapliga institutionen

   Author : Emil Olofsson; [2023]
   Keywords : EU Forest Strategy for 2030; Swedish Forest Policy; Discourse Analysis; Just Transitio;

   Abstract : The new EU Forest Strategy for 2030, one of the flagship initiatives of the European Green Deal, has put EU forest policy in a new expansionary phase with ambitious goals for future forest management in Member States. This thesis analyzes contestation over the EU Forest Strategy for 2030 in Sweden to understand how discursive representations of forests are interlinked with justice perceptions. READ MORE

6. 5. Numerical Estimation of Critical Exponents in the 3D XY Model

   University essay from KTH/Fysik

   Author : Christoffer Beiming; [2023]
   Keywords : Theoretical physics; Condensed matter theory; Phase transitions; XY model; Critical exponents; Computational physics; Monte Carlo simulations; Teoretisk fysik; Kondenserade materiens teori; Fasövergångar; XY-modellen; Kritiska exponenter; Beräkningsfysik; Monte Carlo simulering;

   Abstract : The experimentally obtained value of the critical exponent ν is presently in significant disagreement with current theoretical predictions for the λ-universality class. We suggest two novel approaches of determining the exponents ν and η by utilizing the effects of finite size scaling. READ MORE
