Applied Maths Seminar: Melcher -- Skyrmions and emergent spin orbit coupling in a spherical magnet

Dear all, 

Our upcoming AM seminar is held Wed 22 March at 1pm, in F11 Chemistry Lecture Theatre
4.  Our speaker is Christof Melcher (RWTH Aachen).  

Talk details follow below:

Title: Skyrmions and emergent spin orbit coupling in a spherical magnet 

Abstract: We discuss solitonic field configurations on a spherical magnet.  Exploiting
the Hamiltonian structure and concepts of angular momentum, we present a new family of
localized solutions to the Landau-Lifshitz equation that are topologically distinct
from the ground state and break rotational symmetry.  The approach illustrates emergent
spin-orbit coupling arising from the loss of individual rotational invariance in spin
and coordinate space---a common feature of condensed matter systems with topological
phases.
