Journal ArticleDOI
Quantum phase transitions of light
TL;DR: In this paper, the authors describe an optical system that exhibits strongly correlated dynamics on a mesoscopic scale by adding photons to a two-dimensional array of coupled optical cavities each containing a single two-level atom in the photonblockade regime.

Spin-valley lifetimes in a silicon quantum dot with tunable valley splitting
C. Yang,Alessandro Rossi,Rusko Ruskov,Nai Shyan Lai,Fahd A. Mohiyaddin,Sukbin Lee,Charles Tahan,Gerhard Klimeck,Andrea Morello,Andrew S. Dzurak +9 more
TL;DR: It is demonstrated that valley separation can be accurately tuned via electrostatic gate control in a metal-oxide-semiconductor quantum dot, providing splittings spanning 0.3-0.8 meV, with a ratio in agreement with atomistic tight-binding predictions.
Journal ArticleDOI
Controllable valley splitting in silicon quantum devices

TL;DR: In this paper, it was shown that the small valley splittings observed in previous experiments on Si-SiGe heterostructures result from atomic steps at the quantum-well interface.
Journal ArticleDOI
Valley Splitting Theory of SiGe/Si/SiGe Quantum Wells
TL;DR: In this paper, an effective mass theory for quantum well was proposed, with an emphasis on calculating the valley splitting, based on a tight binding theory, and the resulting formalism provides rather simple analytical results for several geometries of interest.
