Symmetry Breaking of the Persistent Spin Helix in Quantum Transport appeared on arXiv!

In this work, we show that the physics of the quantum corrections to the conductivity around the persistent spin helix symmetry point can be treated very similar to the case with weak spin-orbit (SO) coupling, where the small parameter is…

Low temperature record published in APL as an Editor's pick, with Scilight!

A Coulomb blockade thermometer was cooled to 2.8 mK with on-and-off chip magnetic refrigeration performed on a pulse tube dilution refrigerator platform... working towards new physics at ultralow temperatures. Published in Applied Physics…

Hyperfine-phonon spin relaxation in a single-electron GaAs quantum dot

Understanding and control of the spin relaxation time T1 is among the key challenges for spin based qubits. A larger T1 is generally favored, setting the fundamental upper limit to the qubit coherence and spin readout fidelity. We establish…
