Atomic quantum similarity indices in position and momentum spaces.
Quantum similarity for atoms is investigated using electron densities in position and momentum spaces. Contrary to the results in position space, the analysis in the momentum space shows how the momentum density carries fundamental information about periodicity and structure of the system and reveals the pattern of Mendeleev's table. A global analysis in the joint r-p space keeps this result.
متن کاملQuantum kinematics on q-deformed quantum spaces II Wave funtions on position and momentum space
The aim of Part II of this paper is to try to describe wave functions on q-deformed versions of position and momentum space. This task is done within the framework developed in Part I of the paper. In order to make Part II self-contained the most important results of Part I are reviewed. Then it is shown that q-deformed exponentials and q-deformed delta functions play the role of momentum and p...
متن کاملAnalysis of complexity measures and information planes of selected molecules in position and momentum spaces.
The Fisher-Shannon and LMC shape complexities and the Shannon-disequilibrium, Fisher-Shannon and Fisher-disequilibrium information planes, which consist of two localization-delocalization factors, are computed in both position and momentum spaces for the one-particle densities of 90 selected molecules of various chemical types, at the CISD/6-311++G(3df,2p) level of theory. We found that while t...
متن کاملCorrelated electron extracule densities in position and momentum spaces
Spherically averaged extracule densities in position, d(R), and momentum, d̄(P), spaces have been calculated for the atoms helium to neon starting from explicitly correlated wave functions. Correlated values for the electron–electron counterbalance density in position, d(0), and in momentum, d̄(0), spaces, and also for the expectation values ^R& and ^P& are reported. A systematic study of the ele...
متن کاملCausal Quantum Mechanics Treating Position and Momentum Symmetrically
De Broglie and Bohm formulated a causal quantum mechanics with a phase space density whose integral over momentum reproduces the position probability density of usual statistical quantum theory. We propose a causal quantum theory with a joint probability distribution such that the separate probability distributions for position and momentum agree with usual quantum theory. Unlike the Wigner dis...
