  • Causal structure of the entanglement renormalization ansatz 
    Beny, Cedric (Bristol : IOP Publishing Ltd., 2013-02-13)
    We show that the multiscale entanglement renormalization ansatz (MERA) can be reformulated in terms of a causality constraint on discrete quantum dynamics. This causal structure is that of de Sitter space with a flat ...
  • Exchange interaction in chirally coupled quantum dots 
    Tutuc, Daniel; Heine, Alexander W.; Schuh, Dieter; Wegscheider, Werner; Haug, Rolf J. (Bristol : IOP Publishing Ltd., 2013)
    We present transport measurements on a system of two lateral quantum dots in a perpendicular magnetic field. Due to edge channel formation in an open conducting region, the quantum dots are chirally coupled. When both ...
  • Magnetoresistance in a High Mobility Two-Dimensional Electron System as a Function of Sample Geometry 
    Bockhorn, L.; Hodaei, A.; Schuh, Dieter; Wegscheider, Werner; Haug, Rolf J. (Bristol : IOP Publishing Ltd., 2013)
    In a high mobility two-dimensional electron gas (2DEG) realized in a GaAs/Al0.3Ga0.7As quantum well we observe changes in the Shubnikov-de Haas oscillations (SdHO) and in the Hall resistance for different sample geometries. ...
