Constraints on Dark Energy from Inflation and the Swampland Conjectures
Jacob M. Leedom
We discuss the prospects of measuring deviations of the dark energy equation of state from w=-1 by using the swampland conjectures to relate inflationary models to quintessence sce…

QCD Axion Dark Matter from a Late Time Phase Transition
Keisuke Harigaya, Jacob M. Leedom
We investigate the possibility that the Peccei-Quinn phase transition occurs at a temperature far below the symmetry breaking scale. Low phase transition temperatures are typical i…

Anomaly cancellation in effective supergravity from the heterotic string with an anomalous U(1)
Mary K. Gaillard, Jacob Leedom
We show that a choice of Pauli-Villars regulators allows the cancellation of all conformal and chiral anomalies in an effective field theory from Z_3 compactification of the hetero…
