Low-rank matrix decompositions for ab initio nuclear structure

open access: yesPhysics Letters B, 2021
The extension of ab initio quantum many-body theory to higher accuracy and larger systems is intrinsically limited by the handling of large data objects in form of wave-function expansions and/or many-body operators.

Bayesian Inverse Quantum Theory [PDF]

open access: yes, 2000
A Bayesian approach is developed to determine quantum mechanical potentials from empirical data. Bayesian methods, combining empirical measurements and "a priori" information, provide flexible tools for such empirical learning problems.

Theoretical-Computational Modeling of Gas-State Thermodynamics in Flexible Molecular Systems: Ionic Liquids in the Gas Phase as a Case Study

open access: yesMolecules, 2022
A theoretical-computational procedure based on the quasi-Gaussian entropy (QGE) theory and molecular dynamics (MD) simulations is proposed for the calculation of thermodynamic properties for molecular and supra-molecular species in the gas phase.

Bypassing the computational bottleneck of quantum-embedding theories for strong electron correlations with machine learning

open access: yesPhysical Review Research, 2021
A cardinal obstacle to performing quantum-mechanical simulations of strongly correlated matter is that, with the theoretical tools presently available, sufficiently accurate computations are often too expensive to be ever feasible.

The Embodied Crossmodal Self Forms Language and Interaction: A Computational Cognitive Review

open access: yesFrontiers in Psychology, 2021
Human language is inherently embodied and grounded in sensorimotor representations of the self and the world around it. This suggests that the body schema and ideomotor action-effect associations play an important role in language understanding, language

Molecular Biology at the Quantum Level: Can Modern Density Functional Theory Forge the Path?

open access: yes, 2012
Recent years have seen vast improvements in the ability of rigorous quantum-mechanical methods to treat systems of interest to molecular biology. In this review article, we survey common computational methods used to study such large, weakly bound ...
