Collapsing universe before time
Gary Shiu, Flavio Tonioni, Hung V. Tran
In this note, we prove analytic bounds on the equation of state of a cosmological fluid composed of an arbitrary number of canonical scalars evolving in a negative multi-exponentia…
Connecting flux vacua through scalar field excursions
Gary Shiu, Flavio Tonioni, Vincent Van Hemelryck +1
We show how flux vacua that differ from each other in flux quanta can be seen as different vacua in a single scalar potential of an enlarged field space, which resolves the separat…
Super-Resolution Emulation of Large Cosmological Fields with a 3D Conditional Diffusion Model
Adam Rouhiainen, Michael Gira, Moritz Münchmeyer +2
High-resolution (HR) simulations in cosmology, in particular when including baryons, can take millions of CPU hours. On the other hand, low-resolution (LR) dark matter simulations…
