EU:s konkurrensrätt och Artikel 102 FEUF syftar till att förhindra snedvridningar av konkurrensen. Enligt ekonomisk teori så ökar en frimarknadsekonomi samhällsnyttan genom konkurrens. Denna slutsats kan motiveras av de två teoretiska modellerna perfekt konkurrens och dess motsats monopol, en total avsaknad av konkurrens. Ett viktigt undantag till detta antagande existerar i de fall där monopol ärEU competition law, and Article 102 TFEU, strives to prevent the distortion of competition. According to economic theory, a free market economy where resources are allocated through competition can generally be expected to increase the total utility of society. The theoretical models of perfect competition and its opposite monopoly, a total lack of competition, motivates this conclusion. An import

This study aims to provide a better understanding of how successful late entrants narratively construct their brand biographies in order to position themselves favorably in the market with already dominant players. A multiple case study with two different late entrants, Everlane and Too Faced, has been analyzed by using narratological theories based upon Algirdas Greimas’s hierarchical order of su

The appearence of quantum chaos in the excited rapidly rotating nucleus is studied in a simple nuclear model, consisting of the cranked Nilsson model with a schematic two-body interaction added. Chaos is found to smoothly set in at a much lower excitation energy in normal-deformed 168Yb than in superdeformed 152Dy. A dynamical sign of chaos is a saturation of the standard deviation of the E2-stren

Research concerning nano-materials (metal-organic frameworks (MOFs), zeolites, mesoporous silicas, etc.) and the nano-scale, including potential barriers for the particulates to diffusion to/from is of increasing importance to the understanding of the catalytic utility of porous materials when combined with any potential super structures (such as hierarchically porous materials). However, it is di

In this thesis, quantum transport through nanostructures is addressed theoretically by considering simplified model systems representing the most important features of quantum dots or molecules. The generic model consists of a central region coupled to noninteracting leads. The key ingredients are a discrete level spectrum of the central region and complicated many-body interactions present therei

This thesis investigates few-body quantum rings, particularly in the study of ultracold bosonic gases and nanowire quantum dots. These systems are investigated numerically using exact diagonalization methods. This dissertation contains five chapters which develop numerical and theoretical background for understanding the few-body calculations and analysis contained in the four included papers: Pap

The two-dimensional kagome lattice is an experimental playground for novel physical phenomena, from frustrated magnetism and topological matter to chiral charge order and unconventional superconductivity. A newly identified kagome superconductor, Ta2V3.1Si0.9 has recently gained attention for possessing a record high critical temperature, TC = 7.5 K for kagome metals at ambient pressure. In this s

Core-shell (CS) quantum dots (QDs) are promising light absorbers for solar cell applications mainly because of their enhanced photostability compared with bare QDs. Moreover, the superb photostability can be combined with a low number of defects by using CSQDs with a gradient composition change from the core to the shell. Here, we study electron injection from the gradient CSQDs to ZnO nanoparticl

We study changes in the steady-state absorption and ultrafast transient absorption kinetics of the photoirradiated CdSe quantum dotZnO system. The changes enable us to reconstruct kinetics of trap creation, which are analyzed with respect to three possible models: trap creation without recovery, trap creation and recovery, and trap creation with an upper limit for trap number accommodated on a qua

A combined quantum mechanical statistical mechanical method has been used to study the solvation of the hydronium ion in water. The system is divided in three parts, a quantum core (the ion), 89 classical water molecules and a dielectric continuum. The water molecules are represented using a polarizable potential. The first solvation shell of the ion consists of three water molecules linked by hyd

A combined quantum mechanical-statistical mechanical method has been used to study the behavior of the hydroxyl ion in water. The system is divided into three parts, a quantum core (the ion), 89 classical water molecules, and a dielectric continuum. The water molecules are represented using a polarizable potential. The first solvation shell consists of four water molecules, two linked by hydrogen

Particulate methane monooxygenase (pMMO) is one of the few enzymes that can activate methane. The metal content of this enzyme has been highly controversial, with suggestions of a dinuclear Fe site or mono-, di-, or trinuclear Cu sites. Crystal structures have shown a mono- or dinuclear Cu site, but the resolution was low and the geometry of the dinuclear site unusual. We have employed quantum ref

Networks composed of independent sources of entangled particles that connect distant users are a rapidly developing quantum technology and an increasingly promising test-bed for fundamental physics. Here we address the certification of their post-classical properties through demonstrations of full network nonlocality. Full network nonlocality goes beyond standard nonlocality in networks by falsify

Characterization of emissions from fires in a laboratory-controlled environment are presented in this report. The project is initiated by the CERN HSE Unit and is called FIRIA, Fire-Induced Radiological Integrated Assessment. The objective of FIRIA is to enhance the knowledge of aerosols emitted from fires in order to develop dispersion models of radiologically-activated material in case of fire.
