Lensing B-modes in the Cosmic Microwave Background polarization

Gravitational lensing causes distortions in the polarization of the Cosmic Microwave Background. In this astrobite, we discuss recent results from the South Pole Telescope collaboration measuring patterns caused by lensing in the CMB polarization. What do these patterns tell us about the Universe?
