# Conifolds and tunneling in the string landscape

@article{Ahlqvist2011ConifoldsAT, title={Conifolds and tunneling in the string landscape}, author={Pontus Ahlqvist and Brian Randolph Greene and David Kagan and Eugene A Lim and Saswat Sarangi and I-Sheng Yang}, journal={Journal of High Energy Physics}, year={2011}, volume={2011}, pages={1-63} }

We investigate flux vacua on a variety of one-parameter Calabi-Yau compactifications, and find many examples that are connected through continuous monodromy transformations. For these, we undertake a detailed analysis of the tunneling dynamics and find that tunneling trajectories typically graze the conifold point — particular 3-cycles are forced to contract during such vacuum transitions. Physically, these transitions arise from the competing effects of minimizing the energy for brane…
