Quantum critical lines in holographic phases with (un)broken symmetry

Goutéraux, B., Kiritsis, E.

Understand

All possible scaling IR asymptotics in homogeneous, translation invariant holographic phases preserving or breaking a U(1) symmetry in the IR are classified.

  • Scale invariant geometries where the scalar extremizes its effective potential are distinguished from hyperscaling violating geometries where the scalar runs logarithmically.
  • It is shown that the general critical saddle-point solutions are characterized by three critical exponents ($\theta, z, \zeta$).
  • Both exact solutions as well as leading behaviors are exhibited.
