soliton_solver: A GPU-based finite-difference PDE solver for topological solitons in two-dimensional non-linear field theories
Paul Leask
This paper introduces soliton_solver, an open-source GPU-accelerated software package for the simulation and real-time visualization of topological solitons in two-dimensional non-…
Compressibility of dense nuclear matter in the -meson variant of the Skyrme model
Miguel Huidobro, Paul Leask, Carlos Naya +1
We show that coupling the -valued Skyrme field to the -meson solves the long-standing issue of (in)compressibility in the solitonic Skyrme model. Even by includi…
Skyrmion crystals stabilized by -mesons
Derek Harland, Paul Leask, Martin Speight
We investigate the ground state crystalline structure of nuclear matter in the -meson variant of the Skyrme model. After minimizing energy with respect to variations of both the…
Baby skyrmion crystals stabilized by vector mesons
Paul Leask
In this letter we study soliton crystals in the -dimensional analogue model of the -dimensional Adkins--Nappi model of nuclear physics. The baby -Skyrme model stud…
