Nanoscale Phase Change Memory with Graphene Ribbon Electrodes
Ashkan Behnam, Feng Xiong, Andrea Cappelli +9
Phase change memory (PCM) devices are known to reduce in power consumption as the bit volume and contact area of their electrodes are scaled down. Here, we demonstrate two types of…
Partition Functions of Non-Abelian Quantum Hall States
Andrea Cappelli, Giovanni Viola
Partition functions of edge excitations are obtained for non-Abelian Hall states in the second Landau level, such as the anti-Read-Rezayi state, the Bonderson-Slingerland hierarchy…
Chiral Partition Functions of Quantum Hall Droplets
A. Cappelli, G. Viola, G. R. Zemba
Chiral partition functions of conformal field theory describe the edge excitations of isolated Hall droplets. They are characterized by an index specifying the quasiparticle sector…
Coulomb Blockade in Hierarchical Quantum Hall Droplets
Andrea Cappelli, Lachezar S. Georgiev, Guillermo R. Zemba
The degeneracy of energy levels in a quantum dot of Hall fluid, leading to conductance peaks, can be readily derived from the partition functions of conformal field theory. Their c…
Thermal Transport in Chiral Conformal Theories and Hierarchical Quantum Hall States
Andrea Cappelli, Marina Huerta, Guillermo R. Zemba
Chiral conformal field theories are characterized by a ground-state current at finite temperature, that could be observed, e.g. in the edge excitations of the quantum Hall effect.…
Numerical Study of Hierarchical Hall Edge States on the Disk Geometry
A. Cappelli, C. Mendez, J. M. Simonin +1
We present a detailed analysis of the exact numerical spectrum of up to ten interacting electrons in the first Landau level on the disk geometry. We study the edge excitations of t…
