Mottness and Holography: Strange Metal from UV-IR Mixing
Abstract : 24 years after the discovery of superconductivity in the copper-oxide ceramics (hereafter cuprates), the central problem remains the anomalous properties of the normal state. The key anomaly is the strange metal in which the resistivity scales as a linear function of temperature rather than the characteristic quadratic dependence of Lev Landau's standard theory of metals. I will show how the strong correlations in the basic model for the cuprates leads naturally to UV-IR mixing and composite excitations which mediate T-linear resistivity. I will also show that a class of bottom-up gravitational models exhibits some of the key ingredients of cuprate physics, including UV-IR mixing and the dynamical generation of a gap. This opens the possibility that holography can uncloak the nature of strongly coupled superconductivity in the cuprates.
The seminar will be held at 3:00pm in 238 . UIC Physics Dept/SES. is located at 845 W Taylor St., Chicago, IL, 60607
