Study of the disordered one-dimensional contact process
Raffaele Cafiero, Andrea Gabrielli, Miguel A. Muñoz
New theoretical and numerical analysis of the one-dimensional contact process with quenched disorder are presented. We derive new scaling relations, different from their counterpar…
Large-scale superconductivity-induced conductance suppression in mesoscopic normal-superconducting structures
R. Seviour, C. J. Lambert, M. Leadbeater
Experiments on hybrid superconducting normal-metal structures have revealed that even in the absence of tunnel junctions the onset of superconductivity can lead to a decrease in th…
Effect of dephasing on mesoscopic conductance fluctuations in quantum dots with single channel leads
Edward McCann, Igor V. Lerner
We consider the distribution of conductance fluctuations in disordered quantum dots with single channel leads. Using a perturbative diagrammatic approach, valid for continuous leve…
Excitation and relaxation in atom-cluster collisions
U. Saalmann, R. Schmidt
Electronic and vibrational degrees of freedom in atom-cluster collisions are treated simultaneously and self-consistently by combining time-dependent density functional theory with…
Charge Transfer in Cluster-Atom Collisions Studied with Non-Adiabatic Quantum Molecular Dynamics
O. Knospe, J. Jellinek, U. Saalmann +1
Charge transfer in collisions of Na_n^+ cluster ions with Cs atoms is investigated theoretically in the microscopic framework of non-adiabatic quantum molecular dynamics. The compe…
Asymmetric gap soliton modes in diatomic lattices with cubic and quartic nonlinearity
Guoxiang Huang, Bambi Hu
Nonlinear localized excitations in one-dimensional diatomic lattices with cubic and quartic nonlinearity are considered analytically by a quasi-discreteness approach. The criteria…
