“…In this regard, given the (theoretical) feasibility of wormholes, the seeking for such geometries is still an active research line (see [3,5] for a self-contained discussion on wormhole. Also see [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25], for recent developments).…”

In this work we construct traversable wormholes geometries in the framework of the complexity factor. We provide the redshift function of a Casimir traversable wormhole which, in combination with a non-vanishing complexity factor, leads to a traversable wormhole with a minimum amount of exotic matter. The shape function and the embedding diagram are shown and discussed. The tidal accelerations and the time required to get through the wormholes are estimated.

“…The asymptotically safe formalism has been successfully applied to gravitational systems [19][20][21][22][23] resolving the problem of the singularity at black holes spacetimes and relates to other methods to describe quantum gravity [24][25][26][27]. The existence of a fixed point for gravitation has been found in several different considerations [28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45].…”

In this paper we investigate the presence of exotic matter and the energy conditions of the generalized Ellis-Bronnikov solutions proposed in [61], a generalization of the Ellis-Bronnikov spacetime that has two parameters defining it (n and r t ) in the context of asymptotically safe gravity (ASG). These generalized solutions was a attempt to solve the problem of exotic matter, and we investigate if the ASG cured these problems.Further, as pointed in [62],these generalized solutions needs an extra matter beyond phantom to exist. Therefore we investigated if the ASG brings what kind of matter these extra matter can be. For this, we have choose the models that use the Ricci scalar, squared Ricci and the Kretschmann scalar to define the antiscreening function. We found that we have corrections at

Finite Action Principle and wormholes

Abstract: In this work, we elaborate on the finite action for wormholes in higher derivative theories. Both non-traversable and traversable wormholes in theories with higher curvature invariants posses finite action.
