  1. Minimal Bosonization of Supersymmetry with Zp-graded Parity

    Article first published online: 13 MAY 2015 | DOI: 10.1002/prop.201400055

    In this paper we consider the inline image-graded parity generalizing the ordinary (or Z2-graded ) parity. Using the inline image-graded parity operator, we discuss the minimal bosonization of the N=2 SUSY with inline image-graded parity. The lowest energy level is shown to be infinitely degenerate. In order to avoid the infinite degeneracy of the ground state we introduce the paraboson algebra to obtain the para-supersymmetry. Finally, we discuss the hidden SUSY with Z3-graded parity.

    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).

  5. Strings of Minimal 6d SCFTs (pages 294–322)

    Babak Haghighat, Albrecht Klemm, Guglielmo Lockhart and Cumrun Vafa

    Article first published online: 21 APR 2015 | DOI: 10.1002/prop.201500014

    Strings associated with minimal 6d SCFTs are studied. By definition they have only one string charge and no Higgs branch and are labelled by an integer n with values 1 ≤ n ≤ 8 or n = 12. Quiver theories have previously been proposed which describe strings of SCFTs for n = 1, 2. For n > 2 the strings interact with the bulk gauge symmetry. In this paper the authors find a quiver description for the n = 4 string using Sen's limit of F-theory and calculate its elliptic genus with localization techniques. This result is checked using the duality of F-theory with M-theory and topological string theory.
