String theory: from the landscape to the swampland.

Mariana Graña

Institut de Physique Théorique, CEA/Saclay, Université Paris-Saclay

String theory is the most compelling candidate that encompasses all  
four interactions observed in nature. While the “first superstring  
revolution” proved the quantum consistency of five string theories,  
the second revolution showed that these were actually five different  
limits of a single theory, consistently defined in ten space-time  
dimensions.  Despite its uniqueness, string theory has a ‘landscape”  
of low-energy solutions with very different observable physics in four  
dimensions. The complement of the landscape is called the swampland,  
and it is defined as the set of effective theories that fulfil all  
consistency conditions at low energies, yet they cannot be coupled to  
a quantum gravity theory at high energies. After introducing string  
theory, in this colloquium we will make an excursion into the  
landscape, trying to avoid the swampland. We will focus in particular  
on the problem of accelerated expansion of the universe.
