Fractional periodicity and magnetism of extended quantum rings
Y. Hancock, J. Suorsa, E. Tölö +1
The magnetic properties and nature of the persistent current in small flux-penetrated rings are investigated. An effective rigid-rotator description is formulated for this…

Spin-droplets in confined quantum Hall systems
E. Rasanen, H. Saarikoski, A. Harju +2
Two-dimensional semiconductor quantum dots are studied in the the filling-factor range 2<v<3. We find both theoretical and experimental evidence of a collective many-body phenomeno…

Stochastic gradient approximation method applied to Hubbard model
A. Harju
The two-dimensional Hubbard model is studied using the variational quantum Monte Carlo technique with Gutzwiller-type variational wave functions. In addition to the simple one-site…
