Edge stability, reconstruction, zero-energy states and magnetism in triangular graphene quantum dots with zigzag edges
Edge stability zero-energy states magnetism
2010/11/17
We present the results of ab-initio density functional theory based calculations of the stability and reconstruction of zigzag edges in triangular graphene quantum dots. We show that, while the recons...
Quantum entanglement between a nonlinear nanomechanical resonator and a microwave field
Quantum entanglement nonlinear nanomechanical resonator microwave field
2010/11/11
We consider a theoretical model for a nonlinear nanomechanical resonator coupled to a superconducting microwave resonator. The nanomechanical resonator is driven parametrically at twice its resonance ...
Infinite disorder scaling of random quantum magnets in three and higher dimensions
Infinite disorder scaling random quantum magnets dimensions
2010/11/11
Using a very efficient numerical algorithm of the strong disorder renormalization group method we have extended the investigations about the critical behavior of the random transverse-field Ising mode...
Wave packet revivals in a graphene quantum dot in a perpendicular magnetic field

2010/10/27
We study the time-evolution of localized wavepackets in graphene quantum dots in a perpendicular magnetic field, focusing on the quasiclassical and revival periodicities, for different values of the m...
The Energy Spectrum of Two-Electron Semiconductor Quantum Dots
Quantum dots Magnetic Field Eigenenergies Energy Gap Splitting
2010/4/9
The ground-state properties of a two-dimensional quantum-dot are studied. We have used the shifted 1/N expansion method to solve the relative part Hamiltonian of two electrons confined in a quantum in...
A Time-Dependent Quantum Study of Li+HF(n=1) -> LiF(n')+H
scattering resonances A Time-Dependent Quantum
2010/4/19
Time-dependent quantum wave packet calculations are performed for a model based (two-dimensional) Li+HF(n=1)\ra LiF(n\prime)+H reaction. The reaction probabilities for a broad range of collison energi...
