Shift orbifolds, decompactification limits, and lattices
Dan Israel, Ilarion V. Melnikov, Yann Proto
We describe the general shift orbifold of a Narain CFT and use this to investigate decompactification limits in the heterotic Narain moduli space. We also comment on higher rank th…
Modeling and Simulation of Transitional Rayleigh-Taylor Flow with Partially-Averaged Navier-Stokes Equations
Filipe S. Pereira, Fernando F. Grinstein, Daniel M. Israel +2
The partially-averaged Navier-Stokes (PANS) equations are used to predict the variable-density Rayleigh-Taylor (RT) flow at Atwood number 0.5 and maximum Reynolds number . Thi…
Partially-Averaged Navier-Stokes Closure Modeling for Variable-Density Turbulent Flow
F. S. Pereira, F. F. Grinstein, D. M. Israel +2
This work extends the framework of the partially-averaged Navier-Stokes (PANS) equations to variable-density flow, \text{i.e.}, multi-material and/or compressible mixing problems w…
Modeling and Simulation of Transitional Taylor-Green Vortex Flow with PANS
Filipe S. Pereira, Fernando Grinstein, Daniel M. Israel +2
The PANS equations model is used to predict the transitional Taylor-Green vortex (TGV) flow at Re=3000. A new form of the closure is proposed, in which the PANS procedure is applie…
Heterotic/type II Duality and Non-Geometric Compactifications
Yoan Gautier, Chris M. Hull, Dan Israël
We present a new class of dualities relating non-geometric Calabi-Yau compactifications of type II string theory to T-fold compactifications of the heterotic string, both preservin…
Non-geometric Calabi-Yau Backgrounds and K3 automorphisms
Chris Hull, Dan Israel, Alessandra Sarti
We consider compactifications of type IIA superstring theory on mirror-folds obtained as K3 fibrations over two-tori with non-geometric monodromies involving mirror symmetries. At…
