Ph.D. Position in Experimental Physics - High Pressure Neutron and X-Ray Studies of Liquid Structure Department of Science and Environment, Roskilde University, invites applications for a position as Ph.D. student of Physics from March 1st 2021 or soon thereafter. The position is for a period of three years. Description of the Ph.D. project The project focuses on detailed structural studies of liquids and glasses (amorphous solids) when subjected to pressure. The scientific question of this project concerns the link between structure and thermodynamics in glass-forming liquids. Particularly the aim is to test a recent theoretical prediction of the existence of so-called “isomorphs”: lines in the pressure-temperature phase diagram along which a liquids structure is invariant. Liquids and amorphous solids do not have the symmetries found in crystalline solids, and understanding liquid structure therefore requires other tools. Part of the goal of this project is to develop a framework of liquid diffraction data analysis, which can be applied for studying the structure of liquids and glasses under inhomogeneous pressure and stress conditions. The PhD project is part of the cross-disciplinary center SOLID (https://solid.dtu.dk/), which aims at visualizing the internal structure of materials in 3D on all the relevant length and time scales using the world most powerful neutron and x-ray sources. The main supervisor will be Professor Kristine Niss andthe project will be carried out in close collaboration with Professor Morten Mattrup Smedskjær (AAU) and Professor Henning Friis Poulsen (DTU). The student will also be part of the Glass and Time center (http://glass.ruc.dk) at Roskilde University’s Department of Science and Environment. Glass and Time is characterized by strong collaboration between experiment, simulation, and theory. The student will be trained in neutron scattering and computational methods associated with the study of liquids and solids. Qualifications The following qualification are required:
