  1. A first principle study of adsorption of two proximate nitrogen atoms on graphene

    Babita Rani and Keya Dharamvir

    Article first published online: 25 JUL 2014 | DOI: 10.1002/qua.24741

    Understanding the details of the interaction of atomic nitrogen impurities with graphene is very important for optimizing the graphene doping process and control the process of incorporation of nitrogen in the sheet, which in turn affects the electronic properties of the material. Theoretical calculations allow the exploration of various configurations for two nitrogen adatoms on graphene, and estimate their relative structural stability and electronic structure.

  2. Effective resistances for ladder-like chains

    In the context of organic Chemistry, it is of interest to have good parameters that can discriminate between molecules with similar shape but different structural properties. In recent years, some new parameters have been considered, for instance, effective resistances and Kirchhoff index (the sum of the effective resistances). In this work, a closed formula for the Kirchhoff index of some (molecular) graphs is presented by reinterpreting these graphs as perturbation of a path.

  3. Best molecular multiple quantum bit for the diatomic molecular quantum computer using potassium nitride and calcium nitride through vibrational progression

    Article first published online: 18 JUL 2014 | DOI: 10.1002/qua.24736

    The potential of KN and CaN as molecular multiple quantum bit for diatomic molecular quantum computers (DMQC) are investigated and supported in this work. Full-CI quantum chemistry calculations of large biological systems are imagined as goal for the realization of DMQC and its application in chemical modeling.

  4. Time-dependent molecular fields created by the interaction of an external electromagnetic field with a molecular system

    Michael Baer

    Article first published online: 15 JUL 2014 | DOI: 10.1002/qua.24734

    The interaction between the Born Oppenheimer non-adiabatic coupling terms (NACT) and an external electromagnetic field, at the vicinity of a conical intersection, is treated. It is shown that such an interaction results in a Wave Equation, for each component of the NACTs:

    In these equations c is the velocity of light, inline image is the time-dependent potential exerted by the dipole interaction with an external field and p and q are any two Cartesian coordinates (the extension to a larger number of coordinates is straightforward).

  5. Investigation of dephasing in an open quantum system under chaotic influence via a fractional Kohn–Sham scheme

    Timothy Ganesan

    Article first published online: 12 JUL 2014 | DOI: 10.1002/qua.24735

    The dephasing of interacting many-electron systems under chaotic influence is an unexplored complex phenomenon. An effort toward a more complete theoretical understanding of its dynamics is performed using fractional formulations. Using this approach, some interesting insights are uncovered and these findings are examined in detail.
