Direct measurement of hyperfine shifts and radiofrequency manipulation of the nuclear spins in individual CdTe/ZnTe quantum dots
G. Ragunathan, J. Kobak, G. Gillard +5
We achieve direct detection of electron hyperfine shifts in individual CdTe/ZnTe quantum dots. For the previously inaccessible regime of strong magnetic fields T, w…

Dynamical suppression of fluctuations in an interacting nuclear spin bath of a self-assembled quantum dot using multiple pulse nuclear magnetic resonance
A. M. Waeber, M. Hopkinson, M. S. Skolnick +1
Electron spin qubit coherence in quantum dots is ultimately limited by random nuclear spin bath fluctuations. Here we aim to eliminate this randomness by making spin bath evolution…

Parity-Time Symmetry in Coherently Coupled Vertical Cavity Laser Arrays
Zihe Gao, Stewart T. M. Fryslie, Bradley J. Thompson +2
We report parity-time (PT) symmetry breaking in electrically injected, coherently coupled, vertical cavity surface emitting laser arrays. We predict beam steering, mode evolution a…
