18:00 → 18:05 Introduction

18:05 → 18:25 Structural and vibrational properties of metal from Infra-Red spectroscopy

In the last decade, ultra-high-pressure physics has generated great interest for the discovery of high-temperature superconductive phases.
This extreme environment presents so many experimental challenges that already characterizing the normal phase is an accomplishment.
The diamond-anvil-cell (the huge press) apparatus prevents exploiting most of the common techniques to investigate what is happening to the sample inside.
The Infra-Red (IR) spectroscopy is the only feasible method to access structural properties in this environment.
Structural information can be retrieved out of the IR spectrum by the comparison of the experimental result with the theoretical simulation of a candidate structure.
This seminar is thought to offer an overview of the main characters that makes the theoretical simulation of the IR spectrum a complicated but surprising task.
