# Quantum Simulator Shows Pseudogap Phenomenon in Fermi–Hubbard Model

Scientists used a quantum simulator to observe a pseudogap, a partial gap in electronic states, in the Fermi–Hubbard model. This phenomenon is closely tied to high-temperature superconductivity and helps clarify how it emerges from strongly correlated electrons. The result provides a new experimental platform for studying quantum materials.
