Core-hole-induced dynamical effects in the x-ray emission spectrum of liquid methanol

Autor: Ljungberg, M. P., Zhovtobriukh, I., Takahashi, O., Pettersson, L. G. M.

We compute the x-ray emission spectrum (XES) of liquid methanol, with the dynamical effects that result from the creation of the core hole included in a semiclassical way. Our method closely reproduces a fully quantum mechanical description of the dy

X-ray Diffraction and Molecular Dynamics Study of Medium-range Order in Ambient and Hot Water

Autor: Huang, Congcong, Wikfeldt, K. T., Nordlund, D., Bergmann, U., McQueen, T., Sellberg, J., Pettersson, L. G. M., Nilsson, A.

We have developed x-ray diffraction measurements with high energy-resolution and accuracy to study water structure at three different temperatures (7, 25 and 66 C) under normal pressure. Using a spherically curved Ge crystal an energy resolution bett

Spatially Inhomogeneous Bimodal Inherent Structure in Simulated Liquid Water

Autor: Wikfeldt, K. T., Nilsson, A., Pettersson, L. G. M.

In the supercooled regime at elevated pressure two forms of liquid water, high-density (HDL) and low-density (LDL), have been proposed to be separated by a coexistence line ending at a critical point, but a connection to ambient conditions has been l
