The threat of destitution as a deterrent against asylum seeking in the European Union

The problematization of asylum has detrimentally impacted on the provision of support for asylum seekers in host countries. The threat of destitution has become instrumental in restrictive asylum policies and is increasingly used as a deterrent against asylum seeking. The EU experience reveals acute tensions between the EU asylum agenda and the EU Member States' obligations under international refugee and human rights law. The provision of support for asylum seekers challenges narrow approaches to the realization of socio-economic rights for "others" and to host countries' duties in that respect. The EU Reception Conditions Directive, which aims to set out standards for the reception of asylum seekers across the Union, exemplifies this predicament. Yet international refugee and human rights law provides a legal framework that establishes minimum standards critical to dignified living for asylum seekers and the protection of the right to seek refugee status in the EU and beyond

Optimized Large Hyperuniform Binary Colloidal Suspensions in Two Dimensions

The creation of disordered hyperuniform materials with potentially extraordinary optical properties requires a capacity to synthesize large samples that are effectively hyperuniform down to the nanoscale. Motivated by this challenge, we propose a fabrication protocol using binary superparamagnetic colloidal particles confined in a 2D plane. The strong and long-ranged dipolar interaction induced by a tunable magnetic field is free from screening effects that attenuates long-ranged electrostatic interactions in charged colloidal systems. Specifically, we find a family of optimal size ratios that makes the two-phase system effectively hyperuniform. We show that hyperuniformity is a general consequence of low isothermal compressibilities, which makes our protocol suitable to systems with other long-ranged soft interactions, dimensionalities and/or polydispersity. Our methodology paves the way to synthesize large photonic hyperuniform materials that function in the visible to infrared range and hence may accelerate the discovery of novel photonic materials

Phase behaviour of the confined lattice gas Lebwohl-Lasher model

The phase behaviour of the Lebwohl-Lasher lattice gas model (one of the simplest representations of a nematogenic fluid) confined in a slab is investigated by means of extensive Monte Carlo simulations. The model is known to yield a first order gas-liquid transition in both the 2D and 3D limits, that is coupled with an orientational order-disorder transition. This latter transition happens to be first order in the 3D limit and it shares some characteristic features with the continuous defect mediated Berezinskii-Kosterlitz-Thouless transition in 2D. In this work we will analyze in detail the behaviour of this system taking full advantage of the lattice nature of the model and the particular symmetry of the interaction potential, which allows for the use of efficient cluster algorithms.Comment: 6 pages, 5 figure
