Graphene: from materials science to particle physics
Joaquín E. Drut, Timo A. Lähde, Eero Tölö
Since its discovery in 2004, graphene, a two-dimensional hexagonal carbon allotrope, has generated great interest and spurred research activity from materials science to particle p…
Quantum Hall droplet laterally coupled to a quantum ring
E. Tölö, A. Harju
We study a two-dimensional cylindrically-symmetric electron droplet separated from a surrounding electron ring by a tunable barrier using the exact diagonalization method. The magn…
Pfaffian and fragmented states at nu=5/2 in quantum Hall droplets
H. Saarikoski, E. Tolo, A. Harju +1
When a gas of electrons is confined to two dimensions, application of a strong magnetic field may lead to startling phenomena such as emergence of electron pairing. According to a…
Effects of thickness in quantum dots at strong magnetic fields
E. Tölö, A. Harju
We study the effects of thickness on the ground states of two-dimensional quantum dots in high magnetic fields. To be specific, we assume the thickness to be small so that only the…
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…
