In this thesis, two quantum dynamical system’s of one and two qubits coupled to a field mode confined in an optical cavity have been studied. Within the Jaynes- and Tavis- Cummings model, the dynamics of the corresponding light-matter interaction was defined in terms of the system’s coupling constants. From the setup of the system, the qubits flying through the cavity, the final state of the syste

Bakgrund: Psykisk ohälsa är vanligt förekommande, kan resultera i nedsatt funktionsförmåga och aktivitetsengagemang samt påverka vardagen negativt med minskad mening. I arbetet för att övervinna psykisk ohälsa kan en arbetsteraput ha en viktig roll genom att möjliggöra aktivitetsengagemang och därmed främja den personliga återhämtningen.

Svensk lagstiftning angående barn och ungdom har under de senaste decennierna varit föremål för ett omfattande reformarbete (Singer 2019: 21). Barn och unga saknar emellertid ofta kunskap om sina rättigheter, samt om hur dessa kan utkrävas. Att samhället har en god kännedom om den lagstiftning som angår barn och ungdom är därför av avgörande betydelse för att barnets rättigheter ska tillgodoses oc

Purpose and research question: The purpose of this study is to investigate whether an improved ESG performance leads to a lower cost of debt, proxied by the yield spread of newly issued corporate bonds and if this effect is more pronounced for firms operating in a stronger institutional environment. We therefore ask the following two research questions: Does a higher ESG score lead to a lower cost

This thesis seeks to examine the transition of three Swedish municipal archives from the old general archive classification system (allmänna arkivschemat) to a new process based classification system (verksamhetsbaserad arkivredovisning). Regulations issued by the Swedish National Archives are not binding for local government archives, and it is therefore free for the municipal archives to decide

Incelrörelsen, en gemenskap baserad på internet bestående av män som lever i ofrivilligt celibat, har fått ökad uppmärksamhet de senaste åren mycket på grund av de våldsdåd som har kopplats till rörelsen. Men forskning uppmanar till att se bortom det kvinnohat och de våldsdåd som incelrörelsen till stor del associeras med för att förstå varför män söker sig till denna omdiskuterade gemenskap. Fors

The nexus between environmental degradation and economic growth is becoming of greater importance globally and in order to limit global warming at an increase of 1.5 ° C there needs to be a net zero-transition towards carbon neutrality. The Kingdom of Bhutan has over the last decades experienced continuous economic growth while being carbon negative and adhering to its unique Gross National Happin

This study is about ssu, a potential norm breaking honorific which reportedly can express intimacy and deference concurrently. While expressing intimacy and deference concurrently is incompatible with Brown and Levinson’s (1978 as cited in Hasegawa, 2015) politeness theory, Hasegawa (2015) provides a modification of their theory that allows for it. Yet, an honorific in hyōjungo ‘standard Japanese’

The implementation of the Single-Use Plastics Directive has gained significant attention due to the detrimental impacts of plastic pollution, leading to the transition from plastic straws to paper straws for Tetra Pak’s portion-size carton packages. However, the acceptance of paper straws could be hindered by negative mouthfeel perceptions, which customers find the difficulties to accurately descr

This thesis aims to analyze the relationship between growth in CO2 per capita and growth in GDP per capita and whether they can grow in different directions- a concept referred to as eco-economic decoupling. By using the latest data and an extensive dataset with econometric analysis techniques, the thesis shows that while there currently is no absolute decoupling - global, economy-wide, and durabl
