From quantum to classical dynamics: The relativistic model in the framework of the real-time functional renormalization group
We investigate the transition from unitary to dissipative dynamics in the
relativistic vector model with the
interaction using the nonperturbative functional renormalization group in the
real-time formalism. In thermal equilibrium, the theory is characterized by two
scales, the interaction range for coherent scattering of particles and the mean
free path determined by the rate of incoherent collisions with excitations in
the thermal medium. Their competition determines the renormalization group flow
and the effective dynamics of the model. Here we quantify the dynamic
properties of the model in terms of the scale-dependent dynamic critical
exponent in the limit of large temperatures and in
spatial dimensions. We contrast our results to the behavior expected at
vanishing temperature and address the question of the appropriate dynamic
universality class for the given microscopic theory.Comment: 32 pages, 12 captioned figures; revised and extended version accepted

‘Birds of a feather’? Assessing the prevalence of anti-immigration attitudes among the far right electorate
This article focuses on the prevalence of anti-immigration attitudes among the far-right electorate. Drawing on the distinction between the predictive power of immigration concerns, and the question of how widespread these concerns are among the far-right voter pool, we proceed in two steps. First, we assess the extent to which anti-immigration attitudes are a necessary condition for voting far right; and second we examine whether far right voters with different levels of anti-immigration attitudes exhibit similar individual and attitudinal characteristics. Using data from the 8th wave of the European Social Survey (ESS) we find that, surprisingly, anti-immigration attitudes are not a necessary condition for voting for the far right as approximately one third of far-right voters have no concerns over immigration. We further show that far-right voters with different levels of immigration concerns have different profiles when it comes to other predictors of the far right-vote including ideological affinity, attachment to the EU and government satisfaction. Our contribution is significant as we suggest that there are different routes to voting for the far right by groups with different grievances, including non- immigration related
