Effective Holographic Theories for low-temperature condensed matter systems

Understand

The IR dynamics of effective holographic theories capturing the interplay between charge density and the leading relevant scalar operator at strong coupling are analyzed.

• Such theories are parameterized by two real exponents $(\gamma,\delta)$ that control the IR dynamics.
• By studying the thermodynamics, spectra and conductivities of several classes of charged dilatonic black hole solutions that include the charge density back reaction fully, the landscape of such theories in view of condensed matter applications is characterized.
• Several regions of the $(\gamma,\delta)$ plane can be excluded as the extremal solutions have unacceptable singularities.
