Free Fermionic Constructions of Heterotic Strings
Ioannis Florakis, John Rizos
This chapter is an introduction to the Free Fermionic Formulation of String Theory, with emphasis on heterotic model building. After a brief review of bosonization in two dimension…
Non-supersymmetric non-tachyonic heterotic vacua with reduced rank in various dimensions
Carlo Angelantonj, Ioannis Florakis, Giorgio Leone +1
We construct rigid non-supersymmetric heterotic vacua with reduced rank and no tachyons in six and four dimensions. These configurations are based on asymmetric orbifold compactifi…
A Lightning Introduction to String Theory
Carlo Angelantonj, Ioannis Florakis
We give a lightning introduction to critical string theory, including the 26-dimensional bosonic string, the 10-dimensional superstrings and heterotic strings with and without spac…
From Free-Fermionic Constructions to Orbifolds and Back
Ioannis Florakis, John Rizos
We systematically develop the explicit map between string vacua constructed in the Free Fermionic Formulation and their toroidal orbifold counterparts. We illustra…
Tachyons and Misaligned Supersymmetry in Closed String Vacua
Carlo Angelantonj, Ioannis Florakis, Giorgio Leone
In a remarkable paper, Dienes discovered that the absence of physical tachyons in closed string theory is intimately related to oscillations in the net number of bosonic minus ferm…
Three-Generation Super No-Scale Models in Heterotic Superstrings
Ioannis Florakis, John Rizos, Konstantinos Violaris-Gountonis
We derive the conditions for the one-loop contribution to the cosmological constant to be exponentially suppressed in a class of heterotic string compactifications with three gener…
