加州理工学院研究人员通过量子模拟器实验，首次直接测量了40年前理论预测的共形场论能级谱1。研究团队利用光学镊子将最多35个锶原子排列成链状结构，采用多体调制分光学技术测量了Ising和三临界Ising共形场论预测的能级比例1。测量结果显示，实验得到的能级比例与理论预测完全相符1，验证了这些基础物理理论的准确性。
这项研究已发表在《自然》杂志2026年第657卷第8130期1。研究得到了美国能源部、国家科学基金会等机构的资助1。研究人员计划将该实验扩展到二维原子网格系统1。
Researchers at the California Institute of Technology have achieved the first direct experimental measurement of a quantum energy spectrum theoretically predicted 40 years ago using a quantum simulator approach.1 The team employed optical tweezers to arrange strontium atoms in a chain configuration and applied many-body modulation spectroscopy techniques to measure the energy level ratios predicted by Ising and tricritical Ising conformal field theories.1 The experimental measurements matched the theoretical predictions.1
The experiments controlled up to 35 strontium atoms using the optical tweezer array platform.1 By directly measuring the energy structure of the Ising and tricritical Ising conformal field theories, the physicists provided empirical validation for these foundational theories in physics.1 The findings have been published in Nature, volume 657, issue 8130, page 98, in September 2026.1 The research was supported by the U.S. Department of Energy and the National Science Foundation, among other institutions.1
Looking ahead, the research team plans to extend their experimental approach to two-dimensional atomic lattice systems.1
