Holographic Van der Waals phase transition for a hairy black hole
The Van der Waals(VdW) phase transition in a hairy black hole is investigated
by analogizing its charge, temperature, and entropy as the temperature,
pressure, and volume in the fluid respectively. The two point correlation
function(TCF), which is dual to the geodesic length, is employed to probe this
phase transition. We find the phase structure in the temperaturegeodesic
length plane resembles as that in the temperaturethermal entropy plane
besides the scale of the horizontal coordinate. In addition, we find the equal
area law(EAL) for the first order phase transition and critical exponent of the
heat capacity for the second order phase transition in the
temperaturegeodesic length plane are consistent with that in
temperaturethermal entropy plane, which implies that the TCF is a good probe
to probe the phase structure of the back hole.Comment: Accepted by Advances in High Energy Physics(The special issue:

Van der Waals phase transition in the framework of holography
Phase structure of the quintessence Reissner-Nordstr\"{o}m-AdS black hole is
probed with the nonlocal observables such as holographic entanglement entropy
and two point correlation function. Our result shows that, as the case of the
thermal entropy, both the observables exhibit the similar Van der Waals-like
phase transition. To reinforce the conclusion, we further check the equal area
law for the first order phase transition and critical exponent of the heat
capacity for the second order phase transition. We also discuss the effect of
the state parameter on the phase structure of the nonlocal observables.Comment: 16 pages, 6 figures. arXiv admin note: text overlap with
