Superadiabatic Forces via the Acceleration Gradient in Quantum Many-Body Dynamics
Molecules, 2019 We apply the formally exact quantum power functional framework (J. Chem. Phys. 2015, 143, 174108) to a one-dimensional Hooke’s helium model atom. The physical dynamics are described on the one-body level beyond the density-based adiabatic approximation ...

Electronic structure of CeAuAl$_3$ using density functional theory
SciPost Physics Proceedings, 2023 We studied the magnetic properties and electronic structure of $CeAuAl_3$ using density functional theory. This compound shows a large Sommerfeld coefficient, a Kondo temperature, ${T_K=4\,K}$ and antiferromagnetic order below ${T_N=1.1\,K}$.

Introducing a new correlation functional in density functional theory
Scientific ReportsThe correlation functional holds significance in density functional theory as it addresses electron–electron interactions beyond the mean-field approximation, enhancing the accuracy of total energy calculations, electronic excitations, and the prediction

Density-functional perturbation theory goes time-dependent
Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2008 The scope of time-dependent density-functional theory (TDDFT) is limited to the lowest portion of the spectrum of rather small systems (a few tens of atoms at most).

Dynamic density functional theory of multicomponent cellular membranes
Physical Review Research, 2023 We present a continuum model trained on molecular dynamics (MD) simulations for cellular membranes composed of an arbitrary number of lipid types. The model is constructed within the formalism of dynamic density functional theory and can be extended to ...

Putting error bars on density functional theory
Scientific ReportsPredicting the error in density functional theory (DFT) calculations due to the choice of exchange–correlation (XC) functional is crucial to the success of DFT, but currently, there are limited options to estimate this a priori.

Efficient learning of a one-dimensional density functional theory
Physical Review Research, 2020 Density functional theory underlies the most successful and widely used numerical methods for electronic structure prediction of solids. However, it has the fundamental shortcoming that the universal density functional is unknown.

Nuclear level density from relativistic density functional theory and combinatorial method
Physics Letters BNuclear level density is calculated with the combinatorial method based on the relativistic density functional theory including pairing correlations. The Strutinsky method is adopted to smooth the total state density in order to refine the prediction at ...
