强关联电子在人工结构中的量子受限为研究关联费米液态在降维中的行为提供了一个平台。强关联氧化物人工结构中金属量子井态的成功产生和控制揭示了二维电子液态的独特行为，其特征是源于V3D态的各向异性轨道特征的轨道选择性量子化和费米能级附近子带的反常带重整化，反映了量子井中复杂的相互作用。

The quantum confinement of strongly correlated electrons in artificial structures provides a platform for studying the behavior of correlated Fermi-liquid states in reduced dimensions. The successful creation and control of metallic quantum well states in artificial structures of a strongly correlated oxide reveals the unique behavior of two-dimensional electron liquid states, characterized by the orbital-selective quantization originating from the anisotropic orbital character of the V 3d states and unusual band renormalization of the subbands near the Fermi level, that reflect complex interactions in the quantum well.
