  • Gautason, Fridrik Freyr; Junghans, Daniel; Zagermann, Marco (New York, NY : Springer International Publishing, 2013)
    We show that the classical cosmological constant in type II flux compactifications can be written as a sum of terms from the action of localized sources plus a specific contribution from non-trivial background fluxes. ...
  • Bhatnagar, Akash; Roy Chaudhuri, Ayan; Kim, Young Heon; Hesse, Dietrich; Alexe, Marin (London : Nature Publishing Group, 2013)
    Recently, the anomalous photovoltaic (PV) effect in BiFeO 3 (BFO) thin films, which resulted in open circuit voltages (V oc) considerably larger than the band gap of the material, has generated a revival of the entire field ...
  • Schmidt, Hennrik; Rode, Johannes C.; Smirnov, Dmitri; Haug, Rolf J. (London : Nature Publishing Group, 2014)
    The electronic properties of bilayer graphene strongly depend on relative orientation of the two atomic lattices. Whereas Bernal-stacked graphene is most commonly studied, a rotational mismatch between layers opens up a ...
