Here, the authors show that a moiré superlattice in bilayer graphene aligned with hexagonal boron nitride drives a topological reconstruction of its electronic bands. Magnetotransport reveals the emergence of massless Dirac fermions in moiré minibands, coexisting with the parent bilayer’s massive carriers. The work highlights moiré engineering as a simple and versatile route to tunable band topology.

The authors uncover here a fundamental link between scattering bounds and the topological features of the radiative phase, associated to a nontrivial winding number, in asymmetric resonators. In the non-Hermitian regime, operating at the derived bound leads to asymmetric resonators that support degenerate coherent perfect absorption (CPA) states that coalesce at an exceptional point (EP), realizing an EP CPA. As a result, this work bridges scattering bounds with critical phenomena in non-Hermitian photonics.

Mott transition from the nonanalyticity of the one-body reduced density-matrix functional

One-body reduced density-matrix functional (1RDMF) theory has yielded promising results for small systems such as molecules, but has not addressed quantum phase transitions. Here, the authors explicitly execute the constrained search within a variational ansatz to construct a 1RDMF for the multiorbital Hubbard model with up to seven orbitals in the thermodynamic limit. The authors find that nonanalytic behavior emerges in their 1RDMF at fixed integer filling, which gives rise to the Mott transition, and illustrates how a nonzero Hund exchange drives the continuous Mott transition to become first order.
