The exponential metric: traversable wormhole and possible identification of scalar background
Eduard Mychelkin, Gulnara Suliyeva, Maxim Makukov
The static antiscalar solution of the Einstein-Klein-Gordon equations in the form of the Papapetrou exponential metric had been interpreted as a traversable wormhole with a throat…
On the weak and strong field effects in antiscalar background
Eduard Mychelkin, Maxim Makukov, Gulnara Suliyeva +1
The triumph of general relativity under the banner "gravity is geometry" began with confirming the crucial effects within the Solar system and proceeded recently to the strong-fiel…
Rotation in vacuum and scalar background: are there alternatives to Newman-Janis algorithm?
Maxim Makukov, Eduard Mychelkin
The Newman-Janis algorithm is the standard approach to rotation in general relativity which, in vacuum, builds the Kerr metric from the Schwarzschild spacetime. Recently, we have s…
Triple path to the exponential metric
Maxim Makukov, Eduard Mychelkin
The exponential Papapetrou metric induced by scalar field conforms to observational data not worse than the vacuum Schwarzschild solution. Here, we analyze the origin of this metri…
The scalarized Raychaudhuri identity and its applications
Eduard G. Mychelkin, Maxim A. Makukov
We show that the covariant Raychaudhuri identity describing kinematic characteristics of space-time admits a representation involving a geometrical scalar which, depending on c…
Simpler than vacuum: Antiscalar alternatives to black holes
Maxim Makukov, Eduard Mychelkin
The Janis-Newman-Winicour and Papapetrou metrics represent counterparts to the Schwarzschild black hole with scalar and antiscalar background fields, correspondingly (where "anti"…
