我们提出了一个分子键的运动图像,在相空间,实时,在分辨率有限的量子不确定性。这些图像是由br2掺杂冰的四波混合测量得到的层析重建Wigner分布函数(WDF)。WDF完全表征了系统的耗散量子演化,尽管与环境耦合,但仍保持量子相干性,其持续的负维格纳洞证明了这一点。WDF的光谱分解允许直接可视化系统的波函数和时空相干性以及系统池相互作用。这些测量生动地说明了在普通凝聚态物质中的多体系统中的非经典波动力学。
We present the moving picture of a molecular bond, in phase-space, in real-time, at resolution limited by quantum uncertainty. The images are tomographically reconstructed Wigner distribution functions (WDF) obtained from four-wave mixing measurements on Br2-doped ice. The WDF completely characterizes the dissipative quantum evolution of the system, which despite coupling to the environment retains quantum coherence, as evidenced by its persistent negative Wigner hole. The spectral decomposition of the WDF allows a direct visualization of wavefunctions and spatiotemporal coherences of the system and the system-bath interaction. The measurements vividly illustrate nonclassical wave mechanics in a many-body system, in ordinary condensed matter.
