Title: plasmons and physical density-density response from holography

Place: Aðalbygging A-069

Time: Thursday October 4, at 1.20 – 2.20 pm

Abstract:

The holographic correspondence can be extended to identify plasmonic excitations in strongly correlated systems. These modes have relevance in the growing field of plasmonics, and play also a crucial role in relating properties of holographic ‘screened’ density-density response response functions to ‘physical’ density-density response functions, with the latter being the quantity actually related to experimental observation.
