Demonstrates the impact of effective impurities on fermionic phase behavior.

Provides insights into impurity effects in strongly correlated systems through holography.

Abstract

We investigate the holographic fermionic phase transition induced by the effective impurity in holography, which is introduced by massless scalar fields in Einstein-Maxwell-massless scalar gravity. We obtain a phase diagram in $(\alpha, T)$ plane separating the Fermi liquid phase and the non-Fermi liquid phase.
