Interacting Quantum Atoms Method for Crystalline Solids. [PDF]
J Phys Chem A, 2021 An implementation of the Interacting Quantum Atoms method for crystals is presented. It provides a real space energy decomposition of the energy of crystals in which all energy components are physically meaningful. The new package ChemInt enables one to compute intra-atomic and inter-atomic energies, as well as electron population measures used for ...

Interacting Quantum Atoms-A Review. [PDF]
Molecules, 2020 The aim of this review is threefold. On the one hand, we intend it to serve as a gentle introduction to the Interacting Quantum Atoms (IQA) methodology for those unfamiliar with it. Second, we expect it to act as an up-to-date reference of recent developments related to IQA.

Tetrel Interactions from an Interacting Quantum Atoms Perspective. [PDF]
Molecules, 2019 Tetrel bonds, the purportedly non-covalent interaction between a molecule that contains an atom of group 14 and an anion or (more generally) an atom or molecule with lone electron pairs, are under intense scrutiny. In this work, we perform an interacting quantum atoms (IQA) analysis of several simple complexes formed between an electrophilic fragment ...

Interacting Quantum Atoms and Multipolar Electrostatic Study of XH···π Interactions. [PDF]
ACS Omega, 2023 The interaction energies of nine XH···π (X = C, N, and O) benzene-containing van der Waals complexes were analyzed, at the atomic and fragment levels, using QTAIM multipolar electrostatics and the energy partitioning method interacting quantum atoms/fragment (IQA/IQF).

Controlling Interactions between Quantum Emitters Using Atom Arrays [PDF]
Physical Review Letters, 2021 We investigate two-dimensional atomic arrays as a platform to modify the electromagnetic environment of individual quantum emitters. Specifically, we demonstrate that control over emission linewidths, resonant frequency shifts, and local enhancement of driving fields is possible due to strong dipole-dipole interactions within ordered, subwavelength ...

Artificial atoms in interacting graphene quantum dots [PDF]
Physical Review B, 2009 We describe the theory of few Coulomb-correlated electrons in a magnetic quantum dot formed in graphene. While the corresponding nonrelativistic (Schr dinger) problem is well understood, a naive generalization to graphene's "relativistic" (Dirac-Weyl) spectrum encounters divergencies and is ill-defined.

Effects of atomic interactions on quantum accelerator modes [PDF]
Physical Review A, 2007 We consider the influence of the inclusion of interatomic interactions on the delta-kicked accelerator model. Our analysis concerns in particular quantum accelerator modes, namely quantum ballistic transport near quantal resonances. The atomic interaction is modelled by a Gross-Pitaevskii cubic nonlinearity, and we address both attractive (focusing ...

Laser-Atom Interaction—Quantum Effects [PDF]
AIP Conference Proceedings, 2009 Our research is focused on the application of quantum coherence induced by the interaction of laser light with atoms. These effects have practical applications in quantum information processing in quantum memories, which are necessary components of quantum optical computers and quantum repeaters.

Quantum computing with magnetically interacting atoms [PDF]
Physical Review A, 2004 We propose a scalable quantum-computing architecture based on cold atoms confined to sites of a tight optical lattice. The lattice is placed in a non-uniform magnetic field and the resulting Zeeman sublevels define qubit states. Microwave pulses tuned to space-dependent resonant frequencies are used for individual addressing.
