The cover page shows absorption images of four Bose-Einstein condensates generated consecutively during the nine seconds of free fall in a single launch of the catapult located at the bottom of the Bremen Drop Tower. The condensates were observed at different times (25, 50, 75 and 100 ms), illustrating the expansion of the wave-packet. This experiment was performed using in a miniaturized ultra-cold atom trap by the QUANTUS collaboration supported by the German Space Agency DLR. The graphics was designed by Jan Rudolph and Holger Ahlers from the group of Prof. Ernst Maria Rasel (Leibniz Universität Hannover).

- Towards one-loop SYM amplitudes from the pure spinor BRST cohomology (pages 105–131)

A method to compute supersymmetric one-loop integrands in ten dimensional SYM theory is outlined. It relies on the constructive interplay between their cubic-graph organization and BRST invariance of the underlying pure spinor superstring description.The five- and six-point amplitudes are presented in a manifestly local form where the kinematic dependence is furnished by BRST-covariant expressions in pure spinor superspace. The results are expected to reproduce any integrated SYM amplitude in dimensions D < 8.
- A Twistorial Approach to Integrability in N=4 SYM (pages 142–147)

While the achievements in the study of N = 4 Super Yang- Mills through the application of integrability are impressive, the precise origins of the exact solvability remain shrouded in mystery. Viewing the problem through the lens of twistor theory should help to clarify the reasons for integrability. The power of this approach is illustrated by rederiving the one-loop spin chain dilatation operator of the model in the SO(6) sector.
