Suppressed decay of a laterally confined persistent spin helix
P. Altmann, M. P. Walser, C. Reichl +2
We experimentally investigate the dynamics of a persistent spin helix in etched GaAs wire structures of 2 to 80 um width. Using magneto-optical Kerr rotation with high spatial reso…
Neutral MSSM Higgs-boson production with heavy quarks: NLO supersymmetric QCD corrections
Stefan Dittmaier, Petra Häfliger, Michael Krämer +2
Within the minimal supersymmetric extension of the Standard Model (MSSM) the associated production of neutral Higgs bosons with top and bottom quarks belongs to the most important…
Dynamics of a localized spin excitation close to the spin-helix regime
G. Salis, M. P. Walser, P. Altmann +2
The time evolution of a local spin excitation in a (001)-confined two-dimensional electron gas subjected to Rashba and Dresselhaus spin-orbit interactions of similar strength is in…
Direct mapping of the formation of a persistent spin helix: Supplementary information
M. P. Walser, C. Reichl, W. Wegscheider +1
The spin-orbit interaction (SOI) in zincblende semiconductor quantum wells can be set to a symmetry point, in which spin decay is strongly suppressed for a helical spin mode. Signa…
Neutral Higgs Boson Decays to Squark Pairs reanalyzed
E. Accomando, G. Chachamis, F. Fugel +2
We analyze neutral Higgs boson decays into squark pairs in the minimal supersymmetric extension of the Standard Model and improve previous analyses. In particular the treatment of…
Role of linear and cubic terms for the drift-induced Dresselhaus spin-orbit splitting in a two-dimensional electron gas
M. Studer, M. P. Walser, S. Baer +6
The Dresselhaus spin-orbit interaction (SOI) of a series of two-dimensional electron gases (2DEGs) hosted in GaAs/AlGaAs and InGaAs/GaAs (001) quantum wells (QWs) is measured by mo…
Low-voltage organic transistors and inverters with ultra-thin fluoropolymer gate dielectric
M. P. Walser, W. L. Kalb, T. Mathis +1
We report on the simple fabrication of hysteresis-free and electrically stable organic field-effect transistors (OFETs) and inverters operating at voltages <1-2 V, enabled by the a…
Charged-Higgs-boson production at the LHC: NLO supersymmetric QCD corrections
Stefan Dittmaier, Michael Krämer, Michael Spira +1
The dominant production process for heavy charged Higgs bosons at the LHC is the associated production with heavy quarks. We have calculated the next-to-leading-order supersymmetri…
