New Shapes of Primordial Non-Gaussianity from Quasi-Single Field Inflation with Multiple Isocurvatons
Michael McAneny, Alexander K. Ridgway
We study a simple extension of quasi-single field inflation in which the inflaton interacts with multiple extra massive scalars known as isocurvatons. Due to the breaking of time t…
Loop-Induced Stochastic Bias at Small Wavevectors
Michael McAneny, Alexander K. Ridgway, Mikhail P. Solon +1
Primordial non-Gaussianities enhanced at small wavevectors can induce a power spectrum of the galaxy overdensity that differs greatly from that of the matter overdensity at large l…
Non-Gaussian Enhancements of Galactic Halo Correlations in Quasi-Single Field Inflation
Haipeng An, Michael McAneny, Alexander K. Ridgway +1
We consider a quasi-single field inflation model in which the inflaton interacts with a massive scalar field called the isocurvaton. Due to the breaking of time translational invar…
Quasi Single Field Inflation in the non-perturbative regime
Haipeng An, Michael McAneny, Alexander K. Ridgway +1
In quasi single field inflation there are massive fields that interact with the inflaton field. If these other fields are not much heavier than the Hubble constant during inflation…
Intrinsic anharmonic effects on the phonon frequencies and effective spin-spin interactions in a quantum simulator made from trapped ions in a linear Paul trap
M. McAneny, J. K. Freericks
The Coulomb repulsion between ions in a linear Paul trap give rise to anharmonic terms in the potential energy when expanded about the equilibrium positions. We examine the effect…
Effect of defects on the phonons and the effective spin-spin interactions of an ultracold Penning trap quantum simulator
M. McAneny, B. Yoshimura, J. K. Freericks
We generalize the analysis of the normal modes for a rotating ionic Coulomb crystal in a Penning trap to allow for inhomogeneities in the system. Our formal developments are comple…
