Planckian charged black holes and their cosmological ramifications
Athanasios G. Tzikas
The application of nonlinear electrodynamics at high energy scales has led to a variety of interesting phenomena in recent years, particularly within the context of non-singular sp…
Regular black holes in isothermal cavity
Athanasios G. Tzikas
We examine the thermodynamic behavior of a static neutral regular (non-singular) black hole enclosed in a finite isothermal cavity. The cavity enclosure helps us investigate black…
Primordial black holes in a dimensionally oxidizing Universe
Konstantinos F. Dialektopoulos, Piero Nicolini, Athanasios G. Tzikas
The spontaneous creation of primordial black holes in a violently expanding Universe is a well studied phenomenon. Based on quantum gravity arguments, it has been conjectured that…
Primordial black holes in a dimensionally reduced universe
Athanasios G. Tzikas, Piero Nicolini, Jonas Mureika +1
We investigate the spontaneous creation of primordial black holes in a lower-dimensional expanding early universe. We use the no-boundary proposal to construct instanton solutions…
Bardeen black hole chemistry
Athanasios G. Tzikas
In the present paper we try to connect the Bardeen black hole with the concept of the recently proposed black hole chemistry. We study thermodynamic properties of the regular black…
Cosmological production of black holes: a way to constrain alternative theories of gravity
Konstantinos F. Dialektopoulos, Antonios Nathanail, Athanasios G. Tzikas
Primordial black holes are considered to be pair created quantum-mechanically during inflation. In the context of General Relativity (GR), it has been shown that the pair creation…
