Rescuing single field inflation from the swampland
The difficulty of building metastable vacua in string theory, has led some to conjecture that in the string theory landscape, potentials satisfy |∇V/V|≥c∼O(1). This condition, which is supported by different explicit constructions, suggests that the EFTs which lead to metastable de-Sitter vacua belo...
