a comprehensive study of schottky barrier mosfet (sbmosfet) scaling issue is performed to determine the role of wafer orientation and structural parameters on the performance of this device within non-equilibrium green's function formalism. quantum confinement increases the effective schottky barrier height (sbh). (100) orientation provides lower effective schottky barrier height in comparison ...

the electronic conductance at zero temperature through a quantum wire with side-connected asymmetric quantum ring (as a scatter system) is theoretically studied using the non-interacting hamiltonian anderson tunneling method. in this paper we concentrate on the configuration of the quantum dot rings. we show that the asymmetric structure of qd-scatter system strongly influences the amplitude an...

In this study, the drug atenolol on C60 fullerene were the drug and its derivatives were optimized fullerene. NBO and NMR for complex computations required in the HF/6-31G (d) and B3LYP/6-31G (d) quantum chemistry method was used. Mechanical quantum calculations in theory level of B3LYP/6-31G were performed on structure of atenolol and nano fullerene atenolol with different positions...

In this paper, using the tight-binding model, we extend the real-space renormalization group method to time-dependent Hamiltonians. We drive the time-dependent recursion relations for the renormalized tight-binding Hamiltonian by decimating selective sites of lattice iteratively. The formalism is then used for the calculation of the local density of electronic states for a one dimensional quant...

We introduce a concept of distance for a space-time where the notion of point is replaced by the notion of physical states e.g. probability distributions. We apply ideas of information theory and compute the Fisher information matrix on such a space-time. This matrix is the metric on that manifold. We apply these ideas to a simple model and show that the Lorentzian metric can be obtained if we ...

The theory of monotone Riemannian metrics on the state space of a quantum system was established by Dénes Petz in 1996. In a recent paper he argued that the scalar curvature of a statistically relevant – monotone – metric can be interpreted as an average statistical uncertainty. The present paper contributes to this subject. It is reasonable to expect that states which are more mixed are less d...
