Thessaloniki ten years on: Injecting momentum into the enlargement process for the Western Balkans. CEPS Commentary, 16 May 2013.

Ten years have passed since the EU-Western Balkans summit was held in Thessaloniki in June 2003. In this new CEPS Commentary, CEPS Associate Senior Fellow Erwan Fouéré exhorts the EU to mark the occasion by reaffirming with greater determination the European perspective for the countries of the region in the hope of keeping the Balkan ghosts at bay.

Reform momentum and its impact on Greek growth. Bruegel Policy Contribution 2015/12, July 2015

Greece has an imperfect track-record of structural reform implementation. However, the poor growth outcome of the Greek programmes is also a consequence of the timing and composition of reforms, which were not optimally geared towards a speedy transition to a new growth model based on the private sector. While the main responsibility for this lies with the Greek authorities, international institutions share the responsibility for the poor growth-enhancing effect of reforms. In the current context, further structural reform efforts should be mainly targeted at supporting Greece's speedy return to solid growth rates. This is not only because poverty and unemployment have reached very high levels, but also for political economy reasons: reforms must quickly be seen to be working in order to buttress the consensus in favour of reform. Further efforts should be made to improve Greece’s business environment and to liberalise product markets, in addition to shifting taxation away from labour and towards consumption. Reforms to improve the quality of institutions should continue and are very much needed in the Greek setting, while taking into account that their demanding implementation might use up administrative capacity and their impact on growth will only be seen over long time horizons.

Georgia and the EU – maintaining the momentum. EPC Commentary, 1 July 2016

The Association Agreement (AA) between Georgia and the European Union (EU), signed in June 2014, will enter into force on 1 July 2016 after having been ratified by the parliaments of the 28 member states. The AA, with its Deep and Comprehensive Free Trade Area (DCFTA), foresees far-reaching political and economic integration with the EU by significantly deepening political and economic ties. Many provisions of the agreement have already begun to be implemented, and some are even beginning to give tangible results, such as the opening up of European markets to Georgian exports. Yet this benchmark moment was somehow overshadowed by the EU’s failure to extend visa free travel to Georgians, as had been expected, despite acknowledging that Georgia had fulfilled all the criteria that had been set. Whilst this was quickly explained by the EU as being only a temporary setback, based on reasons more related to other countries, such as Turkey and Ukraine, with which similar arrangements were being negotiated, it exposed the fragility of maintaining the necessary momentum in Georgia-EU relations.

Unimolecular Rovibrational Bound and Resonance States for Large Angular Momentum: J=20 Calculations for HO2

We explore the calculation of unimolecular bound states and resonances for deep-well species at large angular momentum using a Chebychev filter diagonalization scheme incorporating doubling of the autocorrelation function as presented recently by Neumaier and Mandelshtam [Phys. Rev. Lett. 86, 5031 (2001)]. The method has been employed to compute the challenging J=20 bound and resonance states for the HO2 system. The methodology has firstly been tested for J=2 in comparison with previous calculations, and then extended to J=20 using a parallel computing strategy. The quantum J-specific unimolecular dissociation rates for HO2-> H+O-2 in the energy range from 2.114 to 2.596 eV have been reported for the first time, and comparisons with the results of Troe and co-workers [J. Chem. Phys. 113, 11019 (2000) Phys. Chem. Chem. Phys. 2, 631 (2000)] from statistical adiabatic channel method/classical trajectory calculations have been made. For most of the energies, the reported statistical adiabatic channel method/classical trajectory rate constants agree well with the average of the fluctuating quantum-mechanical rates. Near the dissociation threshold, quantum rates fluctuate more severely, but their average is still in agreement with the statistical adiabatic channel method/classical trajectory results.

Momentum transfer effects in the transport of adsorbate at a nano-patterned surface

Adsorbate molecules scattered in the repulsive field of a surface feature in the form of a semi-cylindrical stripe may be considered as a simple model for a nano-patterned surface. The extent of scattering was conveniently expressed as the tangential momentum accommodation coefficient. An analytical result was obtained using a simple local specular reflection hypothesis in contrast to the more complicated situation of an array of atoms discussed elsewhere, in which screening and secondary reflection may occur (Nicholson and Bhatia 2005). It was also demonstrated that a simple 2D representation leads to the same result for the tangential momentum accommodation coefficient.

First-principles quantum simulations of dissociation of molecular condensates: Atom correlations in momentum space

We investigate the quantum many-body dynamics of dissociation of a Bose-Einstein condensate of molecular dimers into pairs of constituent bosonic atoms and analyze the resulting atom-atom correlations. The quantum fields of both the molecules and atoms are simulated from first principles in three dimensions using the positive-P representation method. This allows us to provide an exact treatment of the molecular field depletion and s-wave scattering interactions between the particles, as well as to extend the analysis to nonuniform systems. In the simplest uniform case, we find that the major source of atom-atom decorrelation is atom-atom recombination which produces molecules outside the initially occupied condensate mode. The unwanted molecules are formed from dissociated atom pairs with nonopposite momenta. The net effect of this process-which becomes increasingly significant for dissociation durations corresponding to more than about 40% conversion-is to reduce the atom-atom correlations. In addition, for nonuniform systems we find that mode mixing due to inhomogeneity can result in further degradation of the correlation signal. We characterize the correlation strength via the degree of squeezing of particle number-difference fluctuations in a certain momentum-space volume and show that the correlation strength can be increased if the signals are binned into larger counting volumes.
