On the Interaction of Monopoles and Domain Walls
Stephon Alexander, Robert Brandenberger, Richard Easther +1
We study the interaction between monopoles and embedded domain walls in a O(3) linear sigma model. We discover that there is an attractive force between the monopole and the wall.…
Higher-Order Methods for Quantum Simulations
A. T. Sornborger, E. D. Stewart
To efficiently implement many-particle quantum simulations on quantum computers we develop and present methods for inverting the Campbell-Baker-Hausdorff lemma to 3rd and 4th order…
The Structure of Cosmic String Wakes (Proceedings)
A. Sornborger, R. Brandenberger, B. Fryxell +1
We present results of a cosmological hydrodynamical study of gravitational accretion in cosmic string wakes and filaments. Cosmic string wakes are formed by fast moving (v ~ c) str…
An Eulerian PPM & PIC Code for Cosmological Hydrodynamics
A. Sornborger, B. Fryxell, K. Olson +1
We present a method for integrating the cosmological hydrodynamical equations including a collisionless dark matter component. For modelling the baryonic matter component, we use t…
