van der Waals Torque in 2D Materials Induced by Interaction between Many-Body Charge Density Fluctuations
Zepu Kou, Yuquan Zhou, Zonghuiyi Jiang +2
Van der Waals torque determines the relative rotational motion between anisotropic objects, being of relevance to low-dimensional systems. Here we demonstrate a substantial torque…
