Magnetic Field Induced Quantum Criticality via new Asymptotically AdS_5 Solutions

Understand

Using analytical methods, we derive and extend previously obtained numerical results on the low temperature properties of holographic duals to four-dimensional gauge theories at finite density in a nonzero magnetic field.

• We find a new asymptotically AdS_5 solution representing the system at zero temperature.
• This solution has vanishing entropy density, and the charge density in the bulk is carried entirely by fluxes.
• The dimensionless magnetic field to charge density ratio for these solutions is bounded from below, with a quantum critical point appearing at the lower bound.
