CPT Violation in String-Modified Quantum Mechanics and the Neutral Kaon System
J. Ellis, N. E. Mavromatos, D. V. Nanopoulos
We show that is in general violated in a non-quantum-mechanical way in the effective low-energy theory derived from string theory, as a result of apparent world-sheet charge…
The String Universe: High Superconductor or Quantum Hall Conductor?
John Ellis, N. E. Mavromatos, D. V. Nanopoulos
Our answer is the latter. Space-time singularities, including the initial one, are described by world-sheet topological Abelian gauge theories with a Chern-Simons term. Their effec…
String Theory Modifies Quantum Mechanics
John Ellis, N. E. Mavromatos, D. V. Nanopoulos
We argue that the light particles in string theory obey an effective quantum mechanics modified by the inclusion of a quantum-gravitational friction term, induced by unavoidable co…
World-Sheet Duality, Space-Time Foam, and the Quantum Fate of a Stringy Black Hole
John Ellis, N. E. Mavromatos, D. V. Nanopoulos
We interpret Minkowski black holes as world-sheet {\it spikes } which are related by world-sheet { \it duality} to {\it vortices } that correspond to Euclidean black holes. These w…
The Origin of Space-Time as Symmetry Breaking in String Theory
John Ellis, N. E. Mavromatos, D. V. Nanopoulos
Physics in the neighbourhood of a space-time metric singularity is described by a world-sheet topological gauge field theory which can be represented as a twisted superconfor…
On the W-hair of String Black Holes and the Singularity Problem
John Ellis, N. E. Mavromatos, D. V. Nanopoulos
We argue that the infinitely many gauge symmetries of string theory provide an infinite set of conserved (gauge) quantum numbers (W-hair) which characterise black hole states and m…
