Optical Two-dimensional Fourier-transform Spectroscopy of Semiconductor Quantum Wells
TLDR
Several two-dimensional projections are shown and techniques to isolate different contributions to the coherent response of semiconductors are demonstrated, which reveal previously unobserved many-body correlations.Abstract:
We demonstrate optical two-dimensional Fourier transform spectroscopy of heavy- and light-hole excitons in GaAs quantum wells. This is enabled by active interferometric stabilization of the excitation pulse separation and of a reference pulse.read more

Principles of nuclear magnetic resonance in one and two dimensions
TL;DR: In this paper, the dynamics of nuclear spin systems were studied by two-dimensional exchange spectroscopy and nuclear magnetic resonance imaging (NEMI) imaging, and two different correlation methods based on coherence transfer were proposed.
