Mode-coupling theory is an approach to the study of complex behavior in the supercooled
liquids which developed from the idea of a nonlinear feedback mechanism. From the …

Guided by the above motto (quotation), we review a broad range of issues lying at the
foundations of Density Functional Theory, DFT, a theory which is currently omnipresent in …

Current studies in density functional theory and density matrix functional theory are
reviewed, with special attention to the possible applications within chemistry. Topics …

Contemporary quantum chemistry presents a quandry. Solution of the Schrodinger equation
proceeds to higher and higher accuracy, and molecular properties are computed ever more …

We present an exact Ansatz for the eigenstate problem of mixed fermion-boson systems that
can be implemented on quantum devices. Based on a generalization of the electronic …

The contracted Schrödinger equation (CSE) technique through its direct determination of the
two-particle reduced density matrix (2RDM) without the wave function may offer a fresh …

In the 1950s several scientists including Joseph Mayer, John Coleman, Per-Olov Lowdin,
and Charles Coulson expounded on the possibilities for using the twoelectron reduced …

Quantum energies and two-particle reduced density matrices (2-rdms) may be determined
without using the N-particle wavefunction by combining the reconstruction of higher rdms …

When Schrödinger1 derived the now-famous equation bearing his name in 1925, new
possibilities emerged for the theoretical and computational prediction of energies and …

The density functional theory is one of the most efficient and promising methods of quantum
physics and chemistry. It is a theory of electronic structure formulated in terms of the electron …
