Putting Liouville String Models of (Quantum) Gravity to Test
Elias Gravanis, Nick E. Mavromatos
Critical String Theory is by definition an -matrix theory. In this sense, (quantum) gravity situations where a unitary -matrix may not be a well-defined concept, as a consequ…
Impulse Action on D-particles in Robertson-Walker Space Times, Higher-Order Logarithmic Conformal Algebras and Cosmological Horizons
Elias Gravanis, Nick E. Mavromatos
We demonstrate that an impulse action (`recoil') on a D-particle embedded in a (four-dimensional) cosmological Robertson-Walker (RW) spacetime is described, in a -model framewor…
$tring Theory and an Accelerating Universe
John Ellis, N. E. Mavromatos, D. V. Nanopoulos
An accelerating Universe can be accommodated naturally within non-critical string theory, in which scattering is described by a superscattering matrix $ that does not factorize as…
A study of spacetime distortion around a scattered recoiling D-particle and possible astrophysical consequences
Elias Gravanis, Nick E. Mavromatos
We study a four-dimensional spacetime induced by the recoil of a D(irichlet)-particle, embeded in it, due to scattering by a moving string. The induced spacetime has curvature only…
