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…
Short-range approximation to Casimir wormholes inspired by scalar and electric fields
Remo Garattini, Athanasios G. Tzikas
We investigate a static traversable wormhole sustained by a combination of a minimally coupled scalar field and an electric field, with exotic matter sourced by Casimir energy. Con…
Charged rotating Casimir wormholes
Remo Garattini, Athanasios G. Tzikas
We investigate the conditions under which a rotating traversable wormhole can be supported by a Casimir source in the presence of an external electric field. Extending previous stu…
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…
Traversable Wormholes induced by Stress Energy Conservation: combining Casimir Energy with a scalar field
R. Garattini, A. G. Tzikas
We investigate possible manifolds characterizing traversable wormholes in the presence of a scalar field minimally coupled to gravity, which has both kinetic and potential energy.…
