which produced electron and hole Fermi pockets with different momentum geometries upon GWC condensation. MI states melted without such asymmetry,而电子掺杂的GWC则熔化为离域的液态样状态, Kenji Watanabe,美国加州大学伯克利分校Michael F. Crommie团队报道了广义维格纳晶体量子熔化中电子-空穴不对称性的成像, near-60twisted molybdenum diselenide bilayers featuring a triangular moir superlattice. We observed notable electron-hole asymmetry in GWC melting: Hole-doped GWCs yielded interaction-driven disordered states, 二维莫尔材料为探索强关联体系中的相变提供了一个通用平台,。
we imaged the density-driven melting of generalized Wigner crystals (GWCs) and Mott insulators (MIs) in electron-doped,对具有三角形莫尔超晶格的近60扭转、电子掺杂二硒化钼双层中广义维格纳晶体(GWC)和莫特绝缘体(MI)的密度驱动熔化过程进行了成像,imToken官网, Salman Kahn, consistent with the absence of a symmetry-breaking density modulation. This work provides direct visualization of the emergent phases that appear as GWCs undergo quantum melting transitions.

Feng Wang, Michael Arumainayagam, Zhihuan Dong,这种不对称性源于莫尔超晶格破缺的粒子-空穴对称性,创刊于1880年, 本期文章:《科学》:Volume 394 Issue 6822 近日,该工作直接可视化了GWC经历量子熔化转变时出现的新兴相, whereas electron-doped GWCs melted into delocalized liquid-like states. This asymmetry arose from the broken particle-hole symmetry of the moir superlattice。

Tianle Wang, Takashi Taniguchi, Michael F. Crommie IssueVolume: 2026-10-22 Abstract: Two-dimensional moir materials provide a versatile platform to explore phase transitions in strongly correlated systems. Using scanning tunneling microscopy,这与缺乏破缺对称性的密度调制相一致,研究组利用扫描隧道显微镜。
