Instabilities, where initially small fluctuations seed the formation of large-scale structures, govern the dynamics in wide variety of fluid flows. The Rayleigh-Taylor instability (RTI) is an iconic example that leads to the development of mushroom-shaped incursions when immiscible fluids are accelerated into each other. RTI drives structure formation throughout science and engineering including table-top oil and water mixtures; supernova explosions; and inertial confinement fusion.  Despite its ubiquity, controlled laboratory RTI experiments are technically challenging.

Quantum many-body systems can host exotic phases of matter characterized by their quantum entanglement. Among them are phases with topological order. In this talk we discuss how to explore the toric code model in a field (or equivalently the Fradkin-Shenker lattice gauge theory) — a paradigmatic model hosting a Z2 topologically ordered phase and a trivial phase — on a quantum processor [1]. We then focus on the higher-form symmetries of the model. In contrast to global on-site (0-form) symmetries, higher-from symmetries act on subdimensional manifolds.

Moire superlattices in semiconductors are predicted to exhibit a rich variety of interaction-induced topological states. However, experimental demonstrations of such topological states, apart from MoTe2 superlattices [1–8], have remained scarce [9, 10]. Here, we report the first optical detection of quantum anomalous Hall (QAH) states in twisted WSe2 homobilayer (tWSe2). Specifically, we employ polarization-resolved attractive polaron spectroscopy on a dual-gated, 2degree tWSe2 and observe direct signatures of spontaneous time-reversal symmetry breaking at hole filling ν = 1.
