Modern science and technology rely on materials whose usefulness depends on their electronic properties. Semiconductors, for example, are the foundation for the world's computer and telecommunications industries. The frontier of modern solid-state physics lies in understanding the properties of those materials whose physical properties, as a direct consequence of many-body quantum-mechanical interactions, differ spectacularly from those of conventional metals and insulators. These "quantum materials" manifest a wide range of astonishing electronic and magnetic phenomena that embody the central scientific questions challenging the field of condensed matter physics, such as high-temperature superconductivity, colossal magnetoresistance, myriad forms of magnetism and ferroelectricity, and novel admixtures of these states.

现代科学和技术依赖于材料，而材料的有用性取决于它们的电子特性。例如，半导体是世界计算机和电信工业的基础。现代固体物理学的前沿在于理解这些材料的性质，这些材料的物理性质作为多体量子力学相互作用的直接结果，与常规金属和绝缘体的物理性质截然不同。这些“量子材料”表现出广泛的令人惊讶的电子和磁性现象，体现了挑战凝聚态物理学领域的核心科学问题，如高温超导性，巨磁阻，无数形式的磁性和铁电性，以及这些状态的新混合物。
