Superconductivity has been observed in moiré systems such as twisted bilayer graphene,
which host flat, dispersionless electronic bands. In parallel, theory work has discovered that …

Near a magic twist angle, bilayer graphene transforms from a weakly correlated Fermi liquid
to a strongly correlated two-dimensional electron system with properties that are …

After many years of development of the basic tools, quantum simulation with ultracold atoms
has now reached the level of maturity at which it can be used to investigate complex …

INTRODUCTION Physical systems that exhibit topological invariants are naturally endowed
with robustness against perturbations, as was recently demonstrated in many settings in …

There have been significant recent advances in realizing band structures with geometrical
and topological features in experiments on cold atomic gases. This review summarizes …

The ideas of topology have found tremendous success in closed physical systems, but even
richer properties exist in the more general open or dissipative framework. We theoretically …

Geometrical frustration in strongly correlated systems can give rise to a plethora of novel
ordered states and intriguing magnetic phases, such as quantum spin liquids,–. Promising …

Asymmetric coupling amplitudes effectively create an imaginary gauge field, which induces
a non-Hermitian Aharonov-Bohm (AB) effect. Nonzero imaginary magnetic flux invalidates …

We report the first observation of lasing topological edge states in a 1D Su-Schrieffer-
Heeger active array of microring resonators. We show that the judicious use of non …

We present the science and technology roadmap for graphene, related two-dimensional
crystals, and hybrid systems, targeting an evolution in technology, that might lead to impacts …
