On de Sitter Vacua in Type IIA Orientifold Compactifications
Frank Saueressig, Ulrich Theis, Stefan Vandoren
This letter discusses the orientifold projection of the quantum corrections to type IIA strings compactified on rigid Calabi-Yau threefolds. It is shown that N=2 membrane instanton…
Membrane Instantons and de Sitter Vacua
Marijn Davidse, Frank Saueressig, Ulrich Theis +1
We investigate membrane instanton effects in type IIA strings compactified on rigid Calabi-Yau manifolds. These effects contribute to the low-energy effective action of the univers…
Ultracold Superstrings in atomic boson-fermion mixtures
Michiel Snoek, Masudul Haque, S. Vandoren +1
We propose a setup with ultracold atomic gases that can be used to make a nonrelativistic superstring in four spacetime dimensions. In particular, we consider for the creation of t…
Gauging Conformal Algebras with Relations between the Generators
Kris Thielemans, Stefan Vandoren
We investigate the gauging of conformal algebras with relations between the generators. We treat the --algebra as a specific example. We show that the gauge-algebra is in…
