Curvature Invariants for the Alcubierre and Natário Warp Drives
Universe, 2021 A process for using curvature invariants is applied to evaluate the metrics for the Alcubierre and the Natário warp drives at a constant velocity. Curvature invariants are independent of coordinate bases, so plotting these invariants will be free of ...

Black holes, warp drives, and energy conditions
Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy PhysicsFollowing the work of H. Ellis, we study warp drives in the gravitational field of a Schwarzschild black hole. We find that as long as the warp drive crosses the black hole horizon at a subluminal speed, the horizon would be effectively absent inside the

Journal of High Energy Physics, 2020 Abstract We study warped flat geometries in three-dimensional topologically massive gravity. They are quotients of global warped flat spacetime, whose isometries are given by the 2-dimensional centrally extended Poincaré algebra. The latter can be obtained as a certain scaling limit of Warped AdS3 space with a positive cosmological

Walsh‐Hadamard‐transform‐based SC‐FDMA system using WARP hardware
ETRI Journal, 2021 Single‐carrier frequency division multiple access (SC‐FDMA) is currently being used in long‐term evolution uplink communications owing to its low peak‐to‐average power ratio (PAPR). This study proposes a new transceiver design for an SC‐FDMA system based
