Kengo Maeda, Makoto Natsuume, Takashi Okamura
TL;DR
This paper investigates the universality classes of holographic superconductors across different spacetime dimensions, demonstrating they exhibit mean-field static exponents and belong to model A dynamic universality class with z=2.
Contribution
It provides a comprehensive analysis of static and dynamic critical exponents of holographic superconductors, establishing their universality class and mean-field behavior.
Findings
Static critical exponents are mean-field values.
Dynamic universality class is model A with z=2.
Universality class is consistent across dimensions.
Abstract
We study "holographic superconductors" in various spacetime dimensions. We compute most of the static critical exponents in the linear perturbations and show that they take the standard mean-field values. We also consider the dynamic universality class for these models and show that they belong to model A with dynamic critical exponent z=2.
