We report on extensive studies on the intrinsic sensitivity of a combined 3He/Cs magnetometer. The magnetometer relies on the detection of the free spin precession of nuclear spin polarized 3He by optically pumped cesium magnetometers. We characterize the relevant processes involved in the detection and quantify their impact on the total sensitivity of the magnetometer. An expression is derived that predicts the sensitivity of this magnetometer scheme and the results are compared to experiments. Excellent agreement is found between theory and experiments, and implications for an application of a 3He/Cs magnetometer in an experiment searching for a permanent neutron electric dipole moment are discussed.

Background: Historically, fashion was not always gendered. After the Great Masculine Renunciation however, men relinquished their rights to excess of physical aesthetics and being ‘beautiful’. Cultural masculinity and gendered norms have since impacted male fashion and constrained the western male look to being understated and practical. Recently, new male icons have surfaced. Certain celebrity appearances have received coverage by popular media, since they are exhibiting a more androgynous and diverse take on masculinity than what is normally presented in the public sphere. There is a hype surrounding this, displayed online. Increasing sales of menswear also indicates that this hype surrounding men’s fashion might be spreading to the general public. This phenomenon inspires speculation about whether or not the average western millennial man actually adopt this new trend they are said to be the leaders of. Purpose: The purpose of this thesis is to examine and describe the relationship that the millennial men have with fashion, with regards to attitude, subjective norms, and behaviour. Methodology: The research builds on a pragmatist philosophy which allows both interpretivist and positivist positions. This allowed a quantitative method to be conducted, using an abductive approach. The data was collected through a survey, using quantitative questions. The acquired data and was analysed through descriptive statistics. Findings: The main findings show that millennial men should not be treated as a single homogenous cohort in research surrounding fashion. The findings also demonstrate a clear shift in men’s attitudes towards shopping and fashion, showing that it is not a feminine activity. However, the attitude towards “the new style of men” is quite scattered. Thus, it seems that this hype around changing male fashion has only started trickling down from the niche community that is considered to be leading this change. Regarding their behaviour, most men still prefer buying clothes from a brick-and-mortar store and do not use the online environment actively to seek out and consume fashion.

We describe a method for recording the Rabi nutation of nuclear spin polarized ³He by optically pumped cesium magnetometers. The measurement is performed by detecting the time-dependent magnetic field produced by the 3He magnetization. The observed signals are compared to theoretical models and the results are used to precisely trace the evolution of the magnetization. This procedure represents a convenient way to control and measure the Rabi flip angle and the degree of spin polarization in experiments using 3He magnetometers. The method requires only very coarse knowledge of the applied magnetic field’s magnitude.

This thesis analyses the way in which the German-Jewish author Nelly Sachs stages her identity as a poeta vates in her letter correspondence since 1940. This poetic stylisation is interpreted as a reaction to the Holocaust as a negative liminalisation; that is, the exclusion of "the Jews" with the intention of destroying identity and "murdering the soul" of individuals. Nelly Sachs tries to transform the negative liminality which threatens her life into the positive liminality of a poet as a mystic media. This process is mainly based on Martin Bubers existentialist approach towards Chassidism and Kabbalah and relates the process of writing to a mystical understanding of a necessary transformation of the fallen world. However, this transformation of liminality which helps the author to effectively survive surviving, makes it simultaneously impossible for the excluded "Jewess" Nelly Sachs to find her way back into society and community.
