title = "Asymmetric wormholes via electrically charged lightlike branes",
abstract = "We consider a self-consistent Einstein-Maxwell-Kalb-Ramond system in the bulk D=4 space-time interacting with a variable-tension electrically charged lightlike brane. The latter serves both as a material and charge source for gravity and electromagnetism, as well as it dynamically generates a bulk space varying cosmological constant. We find an asymmetric wormhole solution describing two {"}universes{"} with different spherically symmetric black-hole-type geometries connected through a {"}throat{"} occupied by the lightlike brane. The electrically neutral {"}left universe{"} comprises the exterior region of Schwarzschild-de-Sitter (or pure Schwarzschild) space-time above the inner (Schwarzschild-type) horizon, whereas the electrically charged {"}right universe{"} consists of the exterior Reissner-Nordstr{\"o}m (or Reissner-Nordstr{\"o}m-de-Sitter) black hole region beyond the outer Reissner-Nordstr{\"o}m horizon. All physical parameters of the wormhole are uniquely determined by two free parameters - the electric charge and Kalb-Ramond coupling of the lightlike brane.",
