Formation and evolution of kinky vortons (2009)

Battye, Richard A., Pearson, Jonathan A., Pike, Simon, Sutcliffe, Paul M.

We present field theory simulations of a model with Z_2xU(1) symmetry in (2+1)-dimensions. This model has two discrete vacua, allowing for domain walls, and also a conserved Noether charge. For...

Light Nuclei of Even Mass Number in the Skyrme Model (2009)

Battye, Richard A., Manton, Nicholas S., Sutcliffe, Paul M., Wood, Stephen W.

We consider the semiclassical rigid-body quantization of Skyrmion solutions of mass numbers B = 4, 6, 8, 10 and 12. We determine the allowed quantum states for each Skyrmion, and find that they often...

Spinning Skyrmions and the Skyrme Parameters (2005)

Battye, Richard A., Krusch, Steffen, Sutcliffe, Paul M.

The traditional approach to fixing the parameters of the Skyrme model requires the energy of a spinning Skyrmion to reproduce the nucleon and delta masses. The standard Skyrme parameters, which are...

Stable Skyrmions in two-component Bose-Einstein condensates (2001)

Battye, Richard A., Cooper, N. R., Sutcliffe, Paul M.

We show that stable Skyrmions exist in two-component atomic Bose-Einstein condensates, in the regime of phase separation. Using full three-dimensional simulations we find the stable Skyrmions with...

Non-Bogomolny SU(N) BPS Monopoles (1999)

Ioannidou, Theodora, Sutcliffe, Paul M.

For N>2 we present static monopole solutions of the second order SU(N) BPS Yang-Mills-Higgs equations which are not solutions of the first order Bogomolny equations. These spherically symmetric...

To be or knot to be? (1998)

Battye, Richard A., Sutcliffe, Paul M.

It has been suggested recently that knots might exist as stable soliton solutions in a simple three-dimensional classical field theory, opening up a wide range of possible applications in physics and...
