Hello, Goodbye. Bertelsmann Stiftung eupinions brief | January 2020

As the United Kingdom is leaving the European Union all eyes are on the eminent economic effects and future trade negotiations. How the British people feel about the state of their country at this defining moment of their political history has received less attention. In this eupinions brief, we examine how British citizens evaluate the state of their national democracy and the direction of their home country. We also ask what they expect for their personal lives

We’ll be fine. How People in the EU27 View Brexit. eupinions brief | February 2019

The political drama called Brexit leaves observers in London fascinated, appalled or exhausted. Whereas in the UK, the tension seems to intensify with every twist and turn the British take on their way out of the European Union, Europeans on the continent seem to be surprisingly detached. They support their country’s membership in the EU in ever greater numbers, and calmly carry on with their daily business. Don’t they think that they will be affected by Brexit? We decided to ask the

Je t’aime. Moi non plus = I love you. Neither do I. eupinions brief | February 2019

When Emmanuel Macron won the French presidential election with a risky strategy and against all odds in May 2017, spring seemed to break out in Paris. New faces, new dynamics, and the promise to do many things differently and thus better, were in the air and inspired large swathes of the French public. But the protests of the "yellow vests" have in their intensity and perseverance now shaken the last optimist. And they’ve reminded us of how deep the trenches between the political interests in France are – as well as how much energy and effort it takes to navigate them

Great expectations The New European Commission, its Ambition and European Public Opinion. eupinions 2019/2

The Eurozone crisis has pushed reform of the European Union (EU) to the forefront of political debate. How can a Union of 28 states with a population of over half a billion be reformed to weather future economic crises and political challenges? Finding an answer to this question is extremely difficult not only because current reform proposals are so varied, but even more so because we lack insights into the preferences for reform amongst national elites and publics. Although EU support has interested scholars for over three decades now, we virtually know nothing about public support for EU reform. Current research focuses almost exclusively on the causes of support for the current project and fails to provide a sufficient basis for effective reform decisions. Surely, the feasibility and sustainability of EU reform crucially hinges on the support amongst national publics. eupinions examines public support for EU reform by developing a theoretical model and employing cutting-edge data collection techniques. Our findings will aid policy makers to craft EU reform proposals that can secure widespread public support

Rashba spin-orbit coupling and spin precession in carbon nanotubes

The Rashba spin-orbit coupling in carbon nanotubes and its effect on spin-dependent transport properties are analyzed theoretically. We focus on clean non-interacting nanotubes with tunable number of subbands $N$. The peculiar band structure is shown to allow in principle for Datta-Das oscillatory behavior in the tunneling magnetoresistance as a function of gate voltage, despite the presence of multiple bands. We discuss the conditions for observing Datta-Das oscillations in carbon nanotubes.Comment: 12 pages, published versio
