Split-pulse X-ray photon correlation spectroscopy with seeded X-rays from X-ray laser to study atomic-level dynamics
Yuya Shinohara, Taito Osaka, Ichiro Inoue +5
With their brilliance and temporal structure, X-ray free-electron laser can unveil atomic-scale details of ultrafast phenomena. Recent progress in split-and-delay optics (SDO), whi…
Dynamically Correlated Region in Sheared Colloidal Glasses Revealed by Neutron Scattering
Zhe Wang, Takuya Iwashita, Lionel Porcar +6
The microscopic deformation mechanism of charged colloidal glasses with extended-range interactions under shear is investigated by in-situ small-angle neutron scattering, and a dyn…
Local Elasticity in Nonlinear Rheology of Interacting Colloidal Glasses Revealed by Neutron Scattering and Rheometry
Zhe Wang, Takuya Iwashita, Lionel Porcar +7
The flow of colloidal suspensions is ubiquitous in nature and industry. Colloidal suspensions exhibit a wide range of rheological behavior, which should be closely related to the m…
Local Energy Landscape in a Simple Liquid
Takuya Iwashita, Takeshi Egami
It is difficult to relate the properties of liquids and glasses directly to their structure because of complexity in the structure which defies precise definition. The potential en…
Elementary excitations and crossover phenomenon in liquids
T. Iwashita, D. M. Nicholson, T. Egami
The elementary excitations of vibration in solids are phonons. But in liquids phonons are extremely short-lived and marginalized. In this letter through classical and ab-initio mol…
Atomic Mechanism of Flow in Simple Liquids under Shear
Takuya Iwashita, Takeshi Egami
Atomic correlations in a simple liquid in steady-state flow under shear stress were studied by molecular dynamics simulation. The local atomic level strain was determined through t…
