Dynamics of the Compact, Ferromagnetic ν=1 Edge
A. Karlhede, K. Lejnell, S. L. Sondhi
We consider the edge dynamics of a compact, fully spin polarized state at filling factor . We show that there are two sets of collective excitations localized near the edge: t…
Effective Action Studies of Quantum Hall Spin Textures
K. Lejnell, A. Karlhede, S. L. Sondhi
We report on analytic and numerical studies of spin textures in quantum Hall systems using a long-wavelength effective action for the magnetic degrees of freedom derived previously…
Reconstruction of the Quantum Hall Edge
A. Karlhede, K. Lejnell
The sharp ν=1 quantum Hall edge present for hard confinement is shown to have two modes that go soft as the confining potential softens. This signals a second order transition to a…
Quantum Hall Skyrmions with Higher Topological Charge
D. Lilliehook, K. Lejnell, A. Karlhede +1
We have investigated quantum Hall skyrmions at filling factor ν=1 carrying more than one unit of topological, and hence electric, charge. Using a combination of analytic and numeri…
