Quantum stress-energy at timelike boundaries: testing a new beyond-CDM parameter with cosmological data
Oliver H. E. Philcox, Eva Silverstein, Gonzalo Torroba
We analyze the basic cosmological effects of a population of timelike boundaries -- a form of nontrivial spacetime topology -- containing a boundary layer of quantum stress energy.…

Optimizers for Stabilizing Likelihood-free Inference
G. Bruno De Luca, Benjamin Nachman, Eva Silverstein +1
A growing number of applications in particle physics and beyond use neural networks as unbinned likelihood ratio estimators applied to real or simulated data. Precision requirement…

Timelike-bounded holography from a solvable sector of the deformation
Eva Silverstein, Gonzalo Torroba
Recent research has leveraged the tractability of style deformations to formulate timelike-bounded patches of three-dimensional bulk spacetimes including . This pro…
