  • Floquet engineering is often limited by weak light–matter coupling and heating. Now it is shown that exciton-driven fields in monolayer semiconductors produce stronger, longer-lived Floquet effects and reveal hybridization linked to excitonic phases.

  • The authors combine laser excitation and scanning tunnelling spectroscopy to visualize the electron and hole distributions in photoexcited moiré excitons in twisted bilayer WS2. This photocurrent tunnelling microscopy approach enables the study of photoexcited non-equilibrium moiré phenomena at atomic scales.

  • By combining large-scale first-principles GW-BSE calculations and micro-reflection spectroscopy, the nature of the exciton resonances in WSe2/WS2 moiré superlattices is identified, highlighting non-trivial exciton states and suggesting new ways of tuning many-body physics.

  • Plasmons depend strongly on dimensionality. Here the authors show that plasmons in atomically thin metals are qualitatively different from those in a 2D electron gas or metal slab: they are dispersionless at large wavevectors and, in systems such as monolayer TaS2, long-lived enough to be observed experimentally as localized plasmon wave packets.

  • A lateral heterojunction with diode-like electrical transport can be created in a homogeneous MoS2 monolayer by using a substrate in which one segment is made from an amorphous fluoropolymer and another segment from hexagonal boron nitride.

  • Interlayer hybridization in van der Waals stacks is key to understanding their physical properties. This Perspective article discusses the various parameters influencing interlayer hybridization and how they can be controlled, providing a comprehensive guide for designing materials with desired properties.

  • This Perspective provides an overview of the different approaches used to understand the behaviour of materials at different length scales and timescales through computation, and outlines future challenges in the description of complex systems or ultrafast non-equilibrium behaviour.
