Wormhole Thermodynamics at Apparent Horizons

Understand

In this paper, we discuss the thermodynamic properties of the evolving Lorentzian wormhole.

• For the shape function $b(r) = r_{0}^2/r$, it is shown that the wormhole spacetime admits two apparent horizons, the inner and the outer one.
• The inner horizon expands while the outer contracts with the passage of time.
• Corresponding to these horizons, we have three types of wormholes, regular, extreme and the naked wormholes.
