`Spectral flow as a map between N=(2,0)-models'
Abstract:
The space of (2,0) models is of particular interest among all heterotic-string
models because it includes the models with the minimal SO(10) unification
structure. The fermionic Z_2xZ_2 heterotic-string models revealed the
existence of a new symmetry in the space of string configurations under the
exchange of spinors and vectors of the SO(10) GUT group, dubbed spinor-vector
duality. Such symmetries are important for the understanding of the landscape
of string vacua and ultimately for the possible operation of a dynamical
vacuum selection mechanism in string theory. We will discuss how to generalize
this idea to arbitrary internal Conformal Field Theories (CFTs). We will also
see how the spectral flow operator normally acting within a general $(2,2)$
theory can be used as a map between (2,0) models.
