Spin textures, screening and excitations in dirty quantum Hall ferromagnets

Mostra altre versioni (1)

We study quantum Hall ferromagnets in the presence of a random electrostatic impurity potential. Describing these systems with a classical non-linear sigma model and using analytical estimates supported by results from numerical simulations, we examine the nature of the ground state as a function of...
