Optical Frequency Combs from High-Order Sideband Generation
Darren Valovcin, Hunter Banks, Shawn Mack +4
We report on the generation of frequency combs from the recently-discovered phenomenon of high-order sideband generation (HSG). A near-band gap continuous-wave (cw) laser with freq…
Symmetry Breaking of the Persistent Spin Helix in Quantum Transport
Pirmin J. Weigele, D. C. Marinescu, Florian Dettwiler +5
We exploit the high-symmetry spin state obtained for equal Rashba and linear Dresselhaus interactions to derive a closed-form expression for the weak localization magnetoconductivi…
Dynamical birefringence: Electron-hole recollisions as probes of Berry curvature
Hunter B. Banks, Qile Wu, Darren C. Valovcin +5
The direct measurement of Berry phases is still a great challenge in condensed matter systems. The bottleneck has been the ability to adiabatically drive an electron coherently acr…
Stretchable persistent spin helices in GaAs quantum wells
Florian Dettwiler, Jiyong Fu, Shawn Mack +4
The Rashba and Dresselhaus spin-orbit (SO) interactions in 2D electron gases act as effective magnetic fields with momentum-dependent directions, which cause spin decay as the spin…
Electrical spin protection and manipulation via gate-locked spin-orbit fields
F. Dettwiler, J. Fu, S. Mack +4
The spin-orbit (SO) interaction couples electron spin and momentum via a relativistic, effective magnetic field. While conveniently facilitating coherent spin manipulation in semic…
Terahertz electron-hole recollisions in GaAs/AlGaAs quantum wells: robustness to scattering by optical phonons and thermal fluctuations
Hunter Banks, Ben Zaks, Fan Yang +4
Electron-hole recollisions are induced by resonantly injecting excitons with a near-IR laser at frequency into quantum wells driven by a ~10 kV/cm field oscillatin…
