Many-body interaction in semiconductors probed with 2D Fourier spectroscopy
Mikhail Erementchouk, Michael N. Leuenberger, L. J. Sham
A particular difficulty in studying many-body interactions in a solid is the absence of an experimental technique that can directly probe their key characteristics. We show that 2D…
Theory of nonlinear optical spectroscopy of electron spin coherence in quantum dots
Ren-Bao Liu, S. E. Economou, L. J. Sham +1
We study in theory the generation and detection of electron spin coherence in nonlinear optical spectroscopy of semiconductor quantum dots doped with single electrons. In third-ord…
Spin extraction theory and its relevance to spintronics
H. Dery, L. J. Sham
Extraction of electrons from a semiconductor to a ferromagnet as well as the case of injection in the reverse direction may be formulated as a scattering theory. However, the prese…
Fast initialization of the spin state of an electron in a quantum dot in the Voigt configuration
C. Emary, Xiaodong Xu, D. G. Steel +2
We consider the initialization of the spin-state of a single electron trapped in a self-assembled quantum dot via optical pumping of a trion level. We show that with a magnetic fie…
Optically-controlled single-qubit rotations in self-assembled InAs quantum dots
C. Emary, L. J. Sham
We present a theory of the optical control of the spin of an electron in an InAs quantum dot. We show how two Raman-detuned laser pulses can be used to obtain arbitrary single-qubi…
Restoring Coherence Lost to a Slow Interacting Mesoscopic Bath
Wang Yao, Ren-Bao Liu, L. J. Sham
For a two-state quantum object interacting with a slow mesoscopic interacting spin bath, we show that a many-body solution of the bath dynamics conditioned on the quantum-object st…
