Josephson current via an isolated Majorana zero mode
No full textWe study the equilibrium dc Josephson current in a junction between an s-wave and a topological superconductor. Cooper pairs from the s-wave superconducting lead can transfer to the topological side either via an unpaired Majorana zero mode localized near the junction or via the above-gap continuum states. We find that the Majorana contribution to the supercurrent can be switched on when time-reversal symmetry in the conventional lead is broken, e.g., by an externally applied magnetic field inducing a Zeeman splitting. Moreover, if the magnetic field has a component in the direction of the effective spin-orbit field, there will be a Majorana-induced anomalous supercurrent at zero phase difference. These behaviors may serve as a signature characteristic of Majorana zero modes and are accessible to devices with only superconducting contacts.QRD/Wimmer GroupBUS/Quantum Delf
Unified numerical approach to topological semiconductor-superconductor heterostructures
No full textWe develop a unified numerical approach for modeling semiconductor-superconductor heterostructures. All the key physical ingredients of these systems - orbital effect of magnetic field, superconducting proximity effect, and electrostatic environment - are taken into account on equal footing in a realistic device geometry. As a model system, we consider indium arsenide (InAs) nanowires with an epitaxial aluminum (Al) shell, which is one of the most promising platforms for Majorana zero modes. We demonstrate qualitative and quantitative agreement of the obtained results with the existing experimental data. Finally, we characterize the topological superconducting phase emerging in a finite magnetic field and calculate the corresponding topological phase diagram.QRD/Wimmer Grou
Replication Data for: Power and Pride. National Identity and Ethnopolitical Inequality around the World
No full textWhy do some individuals embrace nationalist rhetoric and feel proud of their citizenship while others do not? This article introduces an exchange-theoretic perspective, according to which national pride depends on access to political power. Seen from this perspective, members of ethnic groups that are not represented in national-level government should be less proud of their nation than those included in the polity. Furthermore, ethnic violence in the past or power-sharing arrangements in the present should reduce trust in the future stability of political representation and thus pride in the nation. From a dynamic point of view, members of ethnic groups whose level of political representation decreased in the past should also see their nation in a less positive light today. To show this, the author uses existing surveys to assemble a new data set with answers to a similar question about national pride. It covers 123 countries that comprise 92 percent of the world’s population. For roughly half of these countries, the ethnic groups listed in the surveys could also be found in another data set that contains information on the political status of these groups. Multilevel ordered logistic regressions at both the country and the group level confirm these hypotheses while taking into account a wide range of individual-level and country-level variables discussed in the existing literature

Future e-government research: 13 research themes identified in the eGovRTD2020 project
No full textE-government research has become a recognized research domain and many policies and strategies are formulated for e-government implementations. Most of these target the next few years and limited attention has been giving to the long term. The eGovRTD2020, a European Commission co-funded project, investigated the future research on e-government driven by changing circumstances and the evolution of technology. This project consists of an analysis of the state of play, a scenario-building, a gap analysis and a roadmapping activity. In this paper the roadmapping methodology fitting the unique characteristics of the e-government field is presented and the results are briefly discussed. The use of this methodology has resulted in the identification of a large number of e-government research themes. It was found that a roadmapping methodology should match the unique characteristics of e-government. The research shows the need of multidisciplinary research.Infrastructures, Systems and ServicesTechnology, Policy and Managemen

Robust helical edge transport in quantum spin Hall quantum wells
No full textWe show that edge-state transport in semiconductor-based quantum spin Hall systems is unexpectedly robust to magnetic fields. The origin for this robustness lies in an intrinsic suppression of the edge-state g-factor and the fact that the edge-state Dirac point is typically hidden in the valence band. A detailed k·p band-structure analysis reveals that both InAs/GaSb and HgTe/CdTe quantum wells exhibit such buried Dirac points for a wide range of well thicknesses. By simulating transport in a disordered system described within an effective model, we demonstrate that edge-state transport remains nearly quantized up to large magnetic fields, consistent with recent experiments.Quantum Computing DivisionQN/Theoretical PhysicsQRD/Wimmer Grou
