TL;DR: In this article, the optical detection of strongly correlated phases in semiconducting WSe2/WS2 moire superlattices is presented, revealing a Mott insulator state at one hole per super-lattice site and surprising insulating phases at fractional filling factors of 1/3 and 2/3.

TL;DR: In this paper, the authors used a sensitive optical detection technique and revealed a Mott insulator state at one hole per superlattice site and surprising insulating phases at 1/3 and 2/3 filling of the super-attice, which they assign to generalized Wigner crystallization on the underlying lattice.

TL;DR: The experimental results demonstrate that the 2D GeAs crystals have promising potential for polarization optical applications, and are consistent with the theoretical calculation of band structure and band realignment.

TL;DR: A comprehensive review of 2D magnetism can be found in this paper , where prominent authors with expertise in complementary fields of magnetism (i.e., synthesis, device engineering, magneto-optics, imaging, transport, mechanics, spin excitations, and theory and simulations) have joined together to provide a genome of current knowledge and a guideline for future developments in 2D magnetic materials research.

TL;DR: In this paper, the 2D Wigner crystal lattice was directly visualized in real-space using a specially designed non-invasive STM spectroscopy technique, which employs a graphene sensing layer held close to the WSe2/WS2 superlattice.
