Code generation for AMReX with applications to numerical relativity
Adam J Peterson, Don Willcox, Phillip Moesta
We present a new python/SymPy based code generator for producing executable numerical expressions for partial differential equations in AMReX-based applications. We demonstrate the…
Dark Matter from Axion Strings with Adaptive Mesh Refinement
Malte Buschmann, Joshua W. Foster, Anson Hook +4
Axions are hypothetical particles that may explain the observed dark matter (DM) density and the non-observation of a neutron electric dipole moment. An increasing number of axion…
Dynamics of global and local vortices with orientational moduli
Minoru Eto, Adam Peterson, Fidel I. Schaposnik Massolo +1
The dynamics of both global and local vortices with non-Abelian orientational moduli is investigated in detail. Head-on collisions of these vortices are numerically simulated for p…
Vortons with Abelian and non-Abelian currents and their stability
Gianni Tallarita, Adam Peterson, Stefano Bolognesi +1
We explore vorton solutions in the Witten's model for cosmic strings and in a modified version obtained by introducing a triplet of non-Abeli…
The holographic non-abelian vortex
Gianni Tallarita, Roberto Auzzi, Adam Peterson
We study a fully back-reacted non-abelian vortex solution in an extension of the holographic superconductor setup. The thermodynamic properties of the vortex are computed. We show…
A Simple Model for a Dual Non-Abelian Monopole-Vortex Complex
Gianni Tallarita, Adam Peterson
We investigate the flux-tube joining two equal and opposite electric charges using the dual Ginzburg-Landau model of superconductivity. The model is supplemented with an additional…
