The past decade has witnessed an explosion in the field of quantum materials, headlined by the predictions and discoveries of novel Landau-symmetry-broken phases in correlated electron systems, topological phases in systems with strong spin–orbit coupling, and ultra-manipulable materials platforms based on two-dimensional van der Waals crystals. Discovering pathways to experimentally realize quantum phases of matter and exert control over their properties is a central goal of modern condensed-matter physics, which holds promise for a new generation of electronic/photonic devices with currently inaccessible and likely unimaginable functionalities. In this Review, we describe emerging strategies for selectively perturbing microscopic interaction parameters, which can be used to transform materials into a desired quantum state. Particular emphasis will be placed on recent successes to tailor electronic interaction parameters through the application of intense fields, impulsive electromagnetic stimulation, and nanostructuring or interface engineering. Together these approaches outline a potential roadmap to an era of quantum phenomena on demand.

过去十年见证了量子材料领域的爆炸式增长，其特征是相关电子系统中新颖的Landau对称断裂相，具有强自旋-轨道耦合的系统中的拓扑相以及超可操作的材料平台的预测和发现。基于二维范德华晶体。发现途径以实验方式实现物质的量子相并对其性质进行控制，这是现代凝聚态物理的主要目标，这为具有目前无法使用且可能难以想象的功能的新一代电子/光子器件提供了希望。在这篇综述中，我们描述了用于选择性地扰动微观相互作用参数的新兴策略，这些策略可用于将材料转化为所需的量子态。将特别强调通过应用强场，脉冲电磁刺激以及纳米结构或界面工程来定制电子相互作用参数的最新成功。这些方法共同勾勒出了按需量子现象时代的潜在路线图。
