Gossamer metals
Marcus Kollar
Laughlin's construction of exact gossamer ground states is applied to normal metals. We show that for each variational parameter 0<=g<=1, the paramagnetic or ferromagnetic Gutzwill…

Persistent spin currents in mesoscopic Haldane gap spin rings
Florian Schuetz, Marcus Kollar, Peter Kopietz
Using a modified spin-wave approach, we show that in the presence of an inhomogeneous magnetic field or an in plane inhomogeneous electric field a mesoscopic antiferromagnetic Heis…

Persistent spin currents in mesoscopic Heisenberg rings
Florian Schuetz, Marcus Kollar, Peter Kopietz
We show that at low temperatures T an inhomogeneous radial magnetic field with magnitude B gives rise to a persistent magnetization current around a mesoscopic ferromagnetic Heisen…
