Quantum fine-tuning in stringy quintessence models

We investigate the extent to which quintessence models for dark energy are fine-tuned in the context of recent swampland conjectures. In particular, the issue is whether there is a double fine-tuning in which both V and |∇V| are fine-tuned, or whether there is only a single fine-tuning due to the re...
