Mobilities in Asian-German transnational spaces: Temporary migrants' experiences, perceptions and motivations

Temporary migration has become an increasingly important phenomenon, also within the German migratory context. This report identifies the qualitative characteristics of temporary transnational migration in the German-Asian transnational space. It concentrates on temporary migrants from Asia in Germany and to a lesser degree on German return migrants from Asia in the categories international students, professionals, family members, asylum seekers/refugees, as well as lifestyle migrants. The presented findings are the result of qualitative interviews, in which temporary migrants were asked about their perceptions, experiences and aspirations related to their stays. Based on these results, the report aims to provide an overview about the interviewees’ motivations to migrate, their feelings of acceptance and belonging in the society of destination, the forms and intensity of their transnational links and activities, as well as their future plans. These aspects are separately addressed for the politico-legal, socio-economic and socio-cultural realms and in the conclusion brought together and related to aspects of temporariness

Migrant support initiatives and young mobile people's needs: outcomes of the YMOBILITY project

Intra-EU mobility has become increasingly important over the past years. While there are no legal barriers preventing young intra-EU migrants from studying or working in another EU country, many of them face obstacles with respect to their integration into the destination country. Likewise, those who return to their origin countries after having spent some time abroad are also often confronted with diverse challenges. Support measures provided by the EU or national governments and by civil society organisations play an important role in overcoming those obstacles, which might not always match with migrants’ and returnees’ needs. Drawing on the outcomes of the collaborative project YMOBILITY, which investigated the relationship between young-peoples’ transition from youth to adulthood and their mobility between EU Member States from an international and interdisciplinary perspective, three general findings can be highlighted. First, (re)integration support should include language training and labour market integration measures, but also address other aspects, such as access to housing and cultural integration. Most importantly, efficient support measures need to be tailored to the particular needs of young intra-EU migrants and returnees. Second, support in integration that targets to overcome acculturation issues in the sphere of everyday life is generally offered by civil society, including organisations created by and for migrants and returnees. However, these organisations tend to be underfunded and understaffed, because they are often based on voluntary work, leading to a limited scope and the underuse of their potential. Third, a large group of migrants and returnees are unaware of, or unwilling to use, social support measures, indicating the particular need to provide measures that improve the communication between providers of support and migrants and returnees

Classical and quantum quasi-free position dependent mass; P\"oschl-Teller and ordering-ambiguity

We argue that the classical and quantum mechanical correspondence may play a basic role in the fixation of the ordering-ambiguity parameters. We use quasi-free position-dependent masses in the classical and quantum frameworks. The effective P\"oschl-Teller model is used as a manifested reference potential to elaborate on the reliability of the ordering-ambiguity parameters available in the literature.Comment: 10 page

A singular position-dependent mass particle in an infinite potential well

We consider an unusual singular position=dependent-mass particle in an infinite potential well. The corresponding Hamiltonian is mapped through a point-canonical-transformation and an explicit correspondence between the target Hamiltonian and a Poschl-Teller type reference Hamiltonian is obtained. New ordering ambiguity parametric setting are suggested.Comment: 13 pages, no figures. To appear in Phys. Lett.

Quantum particles trapped in a position-dependent mass barrier; a d-dimensional recipe

We consider a free particle,V(r)=0, with position-dependent mass m(r)=1/(1+zeta^2*r^2)^2 in the d-dimensional schrodinger equation. The effective potential turns out to be a generalized Poschl-Teller potential that admits exact solution.Comment: 6 pages, no figures, to appear in Phys. Lett.

Position-dependent-mass; Cylindrical coordinates, separability, exact solvability, and PT-symmetry

The kinetic energy operator with position-dependent-mass in cylindrical coordinates is obtained. The separability of the corresponding Schr\"odinger equation is discussed within radial cylindrical mass settings. Azimuthal symmetry is assumed and spectral signatures of various z-dependent interaction potentials (Hermitian and non-Hermitian PT-symmetric) are reported.Comment: 16 page
