Brillouin zone labelling for quasicrystals

We propose a scheme to determine the energy-band dispersion of quasicrystals which does not require any periodic approximation and which directly provides the correct structure of the extended Brillouin zones. In the gap labelling viewpoint, this allow to transpose the measure of the integrated density-of-states to the measure of the effective Brillouin-zone areas that are uniquely determined by the position of the Bragg peaks. Moreover we show that the Bragg vectors can be determined by the stability analysis of the law of recurrence used to generate the quasicrystal. Our analysis of the gap labelling in the quasi-momentum space opens the way to an experimental proof of the gap labelling itself within the framework of an optics experiment, polaritons, or with ultracold atoms.Comment: 13 pages, 5 figure

Citation of Maternal Narratives: A Butlerian Reading of Janet Frame's Autobiography

Narratives express and constrain what we might say about experience. In this paper, I want to explain how Janet Frame (1924–2004) was conditioned by her mother to learn and use pre-agreed narratives of family history, the accurate performance of which became the condition of the author's validity as a family member. Drawing on the work of Judith Butler on the citational self, I aim to show the tension between Frame's desire to become a writer of her own making and the constraint found in her early environment, in particular her mother's wish that her daughter should stick to ritualistic repetitions of established narratives. To do so, I will chronicle Frame's developmental journey, described in her autobiography, and using a Butlerian framework, I will explain how Frame finds a distinctive way to cite her own subjectivity. Beyond tension, beyond the stasis of repeated narrative, the author timidly at first then overtly transgresses the maternal injunction for correct citation

The regulation of gender in menopause theory

'The regulation of gender in menopause theory' offers a critical commentary on some key theories of menopause experience. It aims to show that the theorisation of menopause keeps to the same epistemic and ideological lines as hegemonic understandings of gender identity. Narratives of menopause (that is: what one says about one's menopause experience) has become one of the means by which one can learn to cite women's gender correctly. In reverse, relating menopause experience against the grain of established narratives is becoming the means by which one may resist epistemic bias and dominant ideology of gender. Moreover, I am proposing that while menopause experience is an important aspect of gender identity formation and its resistance, it is also becoming a new area for identity politics in general, and more particularly the site of dissident narratives
