Quantum Mechanics and Black Holes in Four-Dimensional String Theory
J. Ellis, N. Mavromatos, D. Nanopoulos
In previous papers we have shown how strings in a two-dimensional target space reconcile quantum mechanics with general relativity, thanks to an infinite set of conserved quantum n…
Modular invariance and nonrenormalizable interactions
S. Kalara, J. Lopez, D. Nanopoulos
We examine the modular properties of nonrenormalizable superpotential terms in string theory and show that the requirement of modular invariance necessitates the nonvanishing of ce…
On the Evaporation of Black Holes in String Theory
J. Ellis, N. E. Mavromatos, D. V. Nanopoulos
We show that, in string theory, the quantum evaporation and decay of black holes in two-dimensional target space is related to imaginary parts in higher-genus string amplitudes. Th…
Flipped SU(5): Origins and Recent Developments
J. Lopez, D. Nanopoulos
We present an account of the early developments that led to the present form of the flipped string model. We focus on the method used to decide on this particular string mo…
Gauge and Matter Condensates in Realistic String Models
S. Kalara, J. Lopez, D. Nanopoulos
We examine the inter-relationship of the superpotential containing hidden and observable matter fields and the ensuing condensates in free fermionic string models. These gauge and…
On the connection between Quantum Mechanics and the geometry of two-dimensional strings
J. Ellis, N. E. Mavromatos, D. V. Nanopoulos
On the basis of an area-preserving symmetry in the phase space of a one-dimensional matrix model - believed to describe two-dimensional string theory in a black-hole background whi…
