近日，美国路易斯安那州立大学Magaa-Loaiza, Omar S.团队研究了量子统计等离子体元晶体。2026年7月15日出版的《自然》杂志发表了这项成果。

设计能够调控量子多体动力学的材料仍然是一项挑战，因为多粒子相互作用通常会引发难以预测的复杂涌现行为。研究组介绍量子统计等离子体超晶格——一种结构，其中由光学近场介导的多粒子动力学产生禁戒量子统计带，从而实现对不同类型光的选择性透射。这一功能源于由纳米天线作为超原子构成的等离子体结构。统计处于允带内的多光子场可无畸变传播，而处于禁戒带内的场则被抑制或被驱使至最近的可行统计态。

研究组证明，这些统计带由超原子的几何排布和集体排列决定，从而为设计量子统计输运提供了一条确定性途径。该平台建立了一种室温量子材料，其对多体光子系统的量子相干性具有内在敏感性，可实现对其的稳健操控和输运。该研究结果对用于能量收集和可扩展多体量子技术的相干敏感光子材料具有启示意义。

Abstract: Engineering materials that control quantum many-body dynamics remains challenging, as multiparticle interactions typically produce complex emergent behaviour that is difficult to predict1,2. Here we introduce quantum statistical plasmonic metacrystals, structures in which the multiparticle dynamics mediated by optical near fields produce forbidden quantum statistical bands that enable selective transmission of different types of light. This functionality arises from a plasmonic structure composed of nanoantennas acting as meta-atoms3. Multiphoton fields with statistics within the allowed bands propagate without distortion, whereas fields in forbidden bands are suppressed or driven towards the nearest accessible statistical state. We show that these bands are determined by the geometry and collective arrangement of the meta-atoms, providing a deterministic route to engineering quantum statistical transport. This platform establishes a room-temperature quantum material intrinsically sensitive to the quantum coherence of many-body photonic systems, enabling their robust manipulation and transport4. Our results have implications for coherence-sensitive photonic materials for energy harvesting and scalable many-body quantum technologies2,5.
