Being less sensitive to systematic effects, the cross-correlations between Cosmic Microwave Background (CMB) data sets and large-scale structures surveys are expected to provide excellent astrophysical and cosmological constraints in the upcoming years. The ongoing CMB polarization experiment POLARBEAR and its upgrade, the Simons Array, will provide one of the best CMB data set for cross-correlation studies. In this talk I will review the latests results and data analysis activity of POLARBEAR and discuss the capabilities of the Simons array for cross-correlation science. If time allows, I will also present recent numerical results aiming at a joint and realistic modeling of the observables involved in cross-correlation studies, the CMB lensing and large-scale structure distribution.
