The study of the spin noise in semiconductors is an intense new research topic within the field of spintronics - a very promising line of the microelectronics research that can lead to important practical applications. While measurements in bulk and quantum dots have been recently reported, the study of two-dimensional electron gases in quantum wells is still open. We propose a collaborative effort on this topic using the large experience of both groups in such systems [see, e.g., VS et al., Nature Phys. 1,31 (2005), FGGH et al., PRB 88, 161305R (2013)], and a very new ultrafast method developed in Michigan [APL 107, 182102 (2015)]. The current FAPESP grant in Sao Paulo, focused in the generation of spin currents, will be also extended towards the investigation of noise and the dynamic nuclear polarization [VS et al., PRL 112, 056601 (2014)] in the current-induced electron spin polarization [VS et al., PRB 90, 085122 (2014), FGGH et al., PRB 90, 041302R (2014)].
