High Temperature Studies of Hydrogen and Deuterium at Extreme Pressures
- Event time: 1:00pm
- Event date: 29th April 2013
- Speaker: Philip Dalladay-Simpson (Formerly School of Physics & Astronomy, University of Edinburgh)
- Location: Room 2511, James Clerk Maxwell Building (JCMB) James Clerk Maxwell Building Peter Guthrie Tait Road Edinburgh EH9 3FD GB
Melting characteristics is an essential diagnostic in studying the properties of the interactions within a material as well as differences between the solid and liquid states. Hydrogen despite being a simple system displays immense complexity and rich physics when under extreme pressures; therefore it is important to broaden our understanding of quantum systems by studying hydrogen in extended pressure-temperature regimes.
Through a series of high temperature Raman spectroscopic experiments we have investigated the melting curve of hydrogen and deuterium in excess of 1000K within the megabar range, conditions previously unattainable. This study will not only show the first experimental melting data on deuterium but also allow for much needed isotopic comparisons in the high temperature regime.
This is a weekly series of informal talks given primarily by members of the soft condensed matter and statistical mechanics groups, but is also open to members of other groups and external visitors. The aim of the series is to promote discussion and learning of various topics at a level suitable to the broad background of the group. Everyone is welcome to attend..
