    簡要記述(中):顆粒體流動(granular flow)的多樣性自古一直缺乏統整的解釋. 但在近期的Phys. Rev. Lett.中, 本所蔡日強實驗室團隊的發現, 為這個統合提供了可能的起點: 主實驗聚焦在觀察緊壓於液體裡膠質顆粒的剪切流(shear flow), 其應力隨施加的轉速呈現的起伏(fluctuations). 此團隊也同時藉由實測,納入"摩擦力隨接觸面行進速度變化"這個久為人知但常被理論忽略的因素, 歸納出新的無因次量(dimensionless number) , 因而解讀出主實驗裡為何在"中等"轉速範圍會出現如地震般的間歇性流動(intermittency):1)這種間歇流的出現, 可視為系統處於(a)較高轉速下類似流沙的"完全液化", 及(b)極低轉速下可比擬於沙漏裡的“準靜態(quasi-static)流動”, 這兩種迥異行為之間的過渡狀態.2) 這些發現也為顆粒流的"固態"(solid), "液態"(liquid), 及 "懸浮態"(suspension) 之間的統合跨出了第一步....
    簡要記述(英):Quicksand, Landslides, and flows in Hourglass: an integrated view----- Could we produce and explain the three vastly different scenarios of granular flow above, in one single experiment? Recently, by carefully observing the shear flow of soft frictional particles immersed in fluid, JC Tsai and co-workers at Institute of Physics, Academia Sinica in Taipei identify a new dimensionless parameter that explicitly takes into account the speed dependence of inter-particle friction, and demonstrate a “dangerous zone” of shear rates with prominent force fluctuations mimicking landslides or earthquakes in nature. This zone also serves as a signature that sits between fully-lubricated flow (as a "fluid", like quicksand) and quasi-static "solid" (in an hourglass).In the past two decades, paradigms have been established in a few idealized contexts, where changes with driving rates are successfully described by dimensionless parameters such as Inertial Number [1] or Viscous Number [2]. However, in our daily lives, behaviors of frictional particles remain largely unexplained. The recent findings by this research team in Taiwan piece together states of "solid", "liquid", and "suspension" of granular flows, "provides a new anchoring point in the climb towards a complete understanding of disordered media flows and should certainly inspire new modeling approaches"--- as remarked by one of the reviewers.-------ORIGINAL ARTICLE: "Signature of transition between granular solid and fluid: Rate-dependent stickslips in steady shearing" (March, 2021) , DoI:10.1103/PhysRevLett.126.128001Extended Readings: [1] Forterre and Pouliquen, Annu.
