Construction of Superconducting Dome and Emergence of Quantum Critical Region in Holography
arxiv(2023)
摘要
In this work, we investigate an extended model of holographic superconductor
by a non-linear electrodynamic interaction coupled to a complex scalar field.
This non-linear interaction term can make a quantum phase transition at zero
temperature with finite charge carrier density. By solving full equations of
motion, we can construct various shapes of the superconducting phase in the
phase diagram. With a specific choice of interaction coefficients, we can
construct a phase diagram with a superconducting dome. Also, we find a new
geometric solution inside the superconducting dome, which turns out to be a
Lifshitz-type geometry. This geometry is characterized by a dynamical critical
exponent, which plays a crucial role near the quantum critical point. We refer
to this region in the phase diagram as a `quantum critical region.'
