Polytropic wormholes
Remo Garattini, Emmanuel N. Saridakis, Athanasios G. Tzikas
Traversable wormholes in general relativity require non-standard matter sources, making the identification of physically motivated equations of state particularly important. We inv…

Noncommutative black holes in extended anti-de Sitter phase space
Athanasios G. Tzikas
We study thermodynamic aspects of ordinary and lower dimensional noncommutative black holes within an extended anti-de Sitter phase space by treating the negative cosmological cons…

Rotating Casimir Wormholes
Remo Garattini, Athanasios G. Tzikas
A Casimir Wormhole is a Traversable Wormhole powered by a Casimir energy source within a static reference frame. A natural extension of this system is the inclusion of rotation. We…
