TL;DR: In this article, the usual insulating behavior in twisted bilayer graphene can be explained by a symmetry breaking that arises when cells in the superlattice are filled with an even number of electrons.

TL;DR: In this article, the authors use a lowest Landau level model to understand the origin of the underlying symmetry-broken correlated state of twisted bilayer graphene, which exhibits a phase transition from a spin-valley polarized insulator to a partial or fully valley unpolarized metal as the bandwidth is increased relative to the interaction strength.

TL;DR: In this article, the authors studied the entropy of minimally entangled purification in three model systems: an Ising spin chain, conformal field theories holographically dual to Einstein gravity, and random stabilizer tensor networks.

TL;DR: In this paper, the authors introduce a numerical algorithm to simulate the time evolution of a matrix product state under a long-ranged Hamiltonian in moderately entangled systems. But their method overcomes the restriction to short-ranged interactions of most existing methods, and it proves particularly useful for studying the dynamics of both power-law interacting, one-dimensional systems, such as Coulombic and dipolar systems, and quasi-two-dimensional, three dimensional systems such as strips or cylinders.

TL;DR: In this article, strong evidence is found that a particular class of exotic states of matter called a Dirac spin liquid is realized in a popular model of numerous magnets, which has long eluded condensed-matter physicists.
