Electrically-induced polarization selection rules of a graphene quantum dot
Qing-Rui Dong, Yan Li, Chun-Xiang Liu
We study theoretically the single-electron triangular zigzag graphene quantum dot in uniform in-plane electric fields. The far-infrared absorption spectra of the dot are calculated…
Strongly-coupled nanotube electromechanical resonators
Guang-Wei Deng, Dong Zhu, Xin-He Wang +11
Coupling an electromechanical resonator with carbon-nanotube quantum dots is a significant method to control both the electronic charge and the spin quantum states. By exploiting a…
Spin noise spectroscopy of quantum dot molecules
Dibyendu Roy, Yan Li, Alex Greilich +3
We discuss advantages and limitations of the spin noise spectroscopy for characterization of interacting quantum dot systems on specific examples of individual singly and doubly ch…
Optical measurements of spin noise as a high resolution spectroscopic tool
Valerii S. Zapasskii, Alex Greilich, Scott A. Crooker +6
The intrinsic fluctuations of electron spins in semiconductors and atomic vapors generate a small, randomly-varying "spin noise" that can be detected by sensitive optical methods s…
Role of Nuclear Quadrupole Coupling on Decoherence and Relaxation of Central Spins in Quantum Dots
N. A. Sinitsyn, Yan Li, S. A. Crooker +2
Strain-induced gradients of local electric fields in semiconductor quantum dots can couple to the quadrupole moments of nuclear spins. We develop a theory describing the influence…
Intrinsic spin fluctuations reveal the dynamical response function of holes coupled to nuclear spin baths in (In,Ga)As quantum dots
Yan Li, N. Sinitsyn, D. L. Smith +5
The problem of how single "central" spins interact with a nuclear spin bath is essential for understanding decoherence and relaxation in many quantum systems, yet is highly nontriv…
