2 weeks agoBistable superlattice switching in a quantum spin Hall insulator
Monolayer TaIrTe4 exhibits bistable superlattice switching between two lattice configurations with dramatically different periodicities, controllable through electrostatic tuning of electronic states.

A grand aspiration of cavity quantum materials research is to uncover fundamentally new routes for controlling properties of matter by judiciously tailoring the quantum electromagnetic environment. Experiments with dark cavities revealed modified transport properties in the integer and fractional quantum Hall states of a 2D electron gas, as well as cavity-assisted thermal control of the metal-to-insulator transition in charge-density-wave systems.

Analogue quantum simulations are a useful tool for investigating these systems, particularly in regimes in which the applicability of numerical techniques is limited. For different simulator platforms, figures of merit include the electron bandwidth and interaction strength, temperature and the number of simulated lattice sites. Their use is further underscored by the ability to realize distinct lattice geometries, on-site degrees of freedom and by the physical observables that are accessible to experimental measurement.

2 months agoDaily briefing: Largest ever 'superposition' pushes quantum boundary
Quantum superposition observed in sodium clusters of ~7,000 atoms suggests macroscopic quantum behavior, while magnetically controllable proteins and 67,800-year-old cave art reveal diverse scientific advances.
