Geodesics in the extended Kähler cone of Calabi-Yau threefolds / Brodie, Callum R. (IPhT, Saclay) ; Constantin, Andrei (Oxford U., Theor. Phys.) ; Lukas, Andre (Oxford U., Theor. Phys.) ; Ruehle, Fabian (Oxford U., Theor. Phys. ; CERN)
We present a detailed study of the effective cones of Calabi-Yau threefolds with $h^{1,1}=2$, including the possible types of walls bounding the Kähler cone and a classification of the intersection forms arising in the geometrical phases. For all three normal forms in the classification we explicitly solve the geodesic equation and use this to study the evolution near Kähler cone walls and across flop transitions in the context of M-theory compactifications.

Swampland Conjectures and Infinite Flop Chains / Brodie, Callum R. (IPhT, Saclay) ; Constantin, Andrei (Oxford U., Theor. Phys. ; U. Oxford (main)) ; Lukas, Andre (Oxford U., Theor. Phys.) ; Ruehle, Fabian (CERN ; Oxford U., Theor. Phys.)
We investigate swampland conjectures for quantum gravity in the context of M-theory compactified on Calabi-Yau threefolds which admit infinite sequences of flops. Naively, the moduli space of such compactifications contains paths of arbitrary geodesic length traversing an arbitrarily large number of Kähler cones, along which the low-energy spectrum remains virtually unchanged.
