Emergence of the persistent spin helix in semiconductor quantum wells
Jake D. Koralek, Chris Weber, Joe Orenstein +4
According to Noethers theorem, for every symmetry in nature there is a corresponding conservation law. For example, invariance with respect to spatial translation corresponds to co…
Two-phonon coupling to the antiferromagnetic phase transition in multiferroic BiFeO3
Mariola O. Ramirez, M. Krishnamurthi, S. Denev +11
A prominent band centered at around 1000-1300 cm-1 and associated with resonant enhancement of two-phonon Raman scattering is reported in multiferroic BiFeO3 thin films and single…
Non-diffusive spin dynamics in a two-dimensional electron gas
C. P. Weber, J. Orenstein, B. Andrei Bernevig +3
We describe measurements of spin dynamics in the two-dimensional electron gas in GaAs/GaAlAs quantum wells. Optical techniques, including transient spin-grating spectroscopy, are u…
Observation of spin Coulomb drag in a two-dimensional electron gas
C. P. Weber, N. Gedik, J. E. Moore +3
An electron propagating through a solid carries spin angular momentum in addition to its mass and charge. Of late there has been considerable interest in developing electronic devi…
Single-quasiparticle stability and quasiparticle-pair decay in YBa2Cu3O6.5 (Ortho II)
N. Gedik, P. Blake, R. C. Spitzer +4
We report results and analysis of time-resolved photoinduced reflectivity experiments on the cuprate superconductor YBa2Cu3O6.5. The sample, which has Tc=45 K, was characterized by…
