A semi-holographic model of non-Fermi liquids

Abstract: In recent years, the holographic correspondence has been used in many contexts to explore properties of strongly coupled systems that are hard to explain by conventional methods. One instance of such systems is given by the high-T superconductors, which exhibit non-Fermi liquid behavior in the so-called "strange metal" phase above the critical temperature. I will discuss the holographic constructions of these systems, and in particular a model that I and my collaborators are currently investigating, based on a semi-holographic approach. I will discuss the results for the transport properties, in particular I will show that under certain conditions an emergent linear-in-T behavior of the longitudinal resistivity appears over a significant range of temperatures.

Frontiers of Holographic Duality-3

Series comments: Having been initially used as a tool to explore strongly coupled phenomena, holography found important applications and intriguing insights in the structure of quantum gravity and quantum information, linking them to certain universal properties of strongly coupled chaotic quantum systems. It provides unified geometric tools for the description of various phenomena in the heavy ions collision physics, many-body physics applications, black hole physics, and quantum information theory.

The aim is to explore a wide variety of aspects of holographic duality, bringing together specialists in main topics to have comprehensive, but intensive discussions of the frontiers of holography and closely related subjects of quantum information and strongly-coupled theory.

The topics to be discussed include holographic duality and applications:

-holographic quantum chromodynamics and heavy ions collisions; -entanglement, chaos and many-body phenomena; -black holes and quantum information.
