Testing Inflation with Large Scale Structure: Connecting Hopes with Reality
Marcelo Alvarez, Tobias Baldauf, J. Richard Bond +25
The statistics of primordial curvature fluctuations are our window into the period of inflation, where these fluctuations were generated. To date, the cosmic microwave background h…
Drifting Oscillations in Axion Monodromy
Raphael Flauger, Liam McAllister, Eva Silverstein +1
We study the pattern of oscillations in the primordial power spectrum in axion monodromy inflation, accounting for drifts in the oscillation period that can be important for compar…
Gravitational Waves and the Scale of Inflation
Mehrdad Mirbabayi, Leonardo Senatore, Eva Silverstein +1
We revisit alternative mechanisms of gravitational wave production during inflation and argue that they generically emit a non-negligible amount of scalar fluctuations. We find the…
The Powers of Monodromy
Liam McAllister, Eva Silverstein, Alexander Westphal +1
Flux couplings to string theory axions yield super-Planckian field ranges along which the axion potential energy grows. At the same time, other aspects of the physics remain essent…
Controlled non-Fermi liquids from spacetime dependent couplings
Xi Dong, Samuel McCandlish, Eva Silverstein +1
We construct perturbatively controlled non-Fermi liquids in 3+1 spacetime dimensions, using mild power-law translation breaking interactions. Our mechanism balances the leading tre…
Backdraft: String Creation in an Old Schwarzschild Black Hole
Eva Silverstein
We analyze string production in the background of a Schwarzschild black hole, after developing first quantized methods which capture string-theoretic nonadiabatic effects which can…
