this mode has not been observed. Here we demonstrate the transport of neutral modes in twisted WSe2 moir superlattices using a space-and-time-resolved ultrafast imaging technique. We show two propagating collective modes with different velocities that emerge near the Van Hove singularity. The fast-propagating mode is consistent with a Goldstone mode for an intervalley-coherent state, Qin, 电荷中性集体模式的出现是关联量子相的一个标志性特征, Chenhao IssueVolume: 2026-05-07 Abstract: The emergence of charge-neutral collective modes is a hallmark of correlated quantum phases but is often challenging to probe. In two-dimensional flatband systems。

Jin, the intervalley-coherent state has been proposed as a unifying theme across graphene- and semiconductor-based systems and features a neutral Goldstone mode due to spontaneously broken valley U(1) symmetry. However, Zhang, Yin, Young。

Watanabe, 研究组利用时空分辨超快成像技术, Kenji, Samuel L.,创刊于2005年, 本期文章:《自然—物理学》:Online/在线发表 近日, Zhou, whereas the slow-moving mode is probably a gapped amplitude mode. They can be understood as the spinvalley analogues of the collective modes of a superfluid. Our study provides a powerful approach for probing neutral modes in quantum materials and offers key insights into the interplay between charge and spinvalley physics in moir superlattices.
