Investigation of electron correlation effects in armchair silicene nanoribbons
In this study, the electronic structure of armchair silicene nanoribbons (ASiNRs) is investigated for various widths using first-principle calculations and the framework of the density functional theory. Electronic structure of ASiNRs shows a direct band gap which is decreased with increasing the nanoribbon's width, showing an oscillatory behavior. The effective Coulomb interaction between loca...
متن کاملA Diagrammatic Approach to Crystalline Color Superconductivity
We present a derivation of the gap equation for the crystalline color superconducting phase of QCD which begins from a one-loop Schwinger-Dyson equation written using a Nambu-Gorkov propagator modified to describe the spatially varying condensate. Some aspects of previous variational calculations become more straightforward when rephrased beginning from a diagrammatic starting point. This deriv...
متن کاملA Diagrammatic Approach to Model Completion
Metamodelling plays an important role in model-driven engineering as it can be used to define domain-specific modelling languages. During the modelling phase, software designers encode domain knowledge into models which may include both structural and behavioural aspects of a system. In this paper we propose a diagrammatic approach to aid the software designer to complete partial models and the...
متن کاملDiagrammatic Approach to Cold Atom-Surface Interactions
We study the sticking rate of cold atoms on elastic membrane by exploring the self-energy Σ of the cold atom. We use the Feynman-Dyson perturbation theory to calculate the free atom self-energy to 1-loop. We find non-zero finite sticking rate Γ that agrees with the Golden rule result in ultra-low energy regime. However, with the 1-loop self-energy insertion, we find a suppressed sticking rate Γ...
متن کاملA New Diagrammatic Approach to Quantum Information
We introduce a new diagrammatic approach to quantum information, that we call holographic software [1]. Our new approach is a small modification of previous diagrammatic approaches, yet our small change leads to a great deal of new understanding and to a large number of new insights and motivation. Its application leads us to new protocols, designed in a “topological” way. (1) The fundamental i...
