M-Theory Model-Building and Proton Stability
John Ellis, Alon E. Faraggi, D. V. Nanopoulos
We study the problem of baryon stability in M theory, starting from realistic four-dimensional string models constructed using the free-fermion formulation of the weakly-coupled he…
On the Space-Time Uncertainty Relations of Liouville Strings and D Branes
G. Amelino-Camelia, J. Ellis, N. E. Mavromatos +1
Within a Liouville approach to non-critical string theory, we argue for a non-trivial commutation relation between space and time observables, leading to a non-zero space-time unce…
D-Brane Recoil Mislays Information
J. Ellis. N. Mavromatos, D. Nanopoulos
We discuss the scattering of a light closed-string state off a brane, taking into account quantum recoil effects on the latter, which are described by a pair of logarithmic ope…
D Branes from Liouville Strings
J. Ellis, N. E. Mavromatos, D. V. Nanopoulos
We develop quantization aspects of our Liouville approach to non-critical strings, proposing a path-integral formulation of a second quantization of string theory, that incorporate…
A string scenario for inflationary cosmology
J. Ellis, N. E. Mavromatos, D. V. Nanopoulos
We describe a scenario for inflation in the framework of non-critical string theory, which does not employ an inflaton field. There is an exponential expansion of the volume of the…
A Non-Critical String Approach to Black Holes, Time and Quantum Dynamics
J. Ellis, N. E. Mavromatos, D. V. Nanopoulos
We review our approach to time and quantum dynamics based on non-critical string theory, developing its relationship to previous work on non-equilibrium quantum statistical mechani…
