Static polarizability and hyperpolarizability in atoms and molecules through a Cartesian-grid DFT
Tanmay Mandal, Abhisek Ghosal, Amlan K. Roy
Static electric response properties of atoms and molecules are reported within the real-space Cartesian grid implementation of pseudopotential Kohn-Sham (KS) density functional the…
Density functional electric response properties of molecules in Cartesian grid
Abhisek Ghosal, Tanmay Mandal, Amlan K. ~Roy
Within the finite-field Kohn-Sham framework, static electric response properties of diatomic molecules are presented. The electronic energy, dipole moment ({\boldmath}), static…
Efficient HF exchange evaluation through Fourier convolution in Cartesian grid for orbital-dependent density functionals
Abhisek Ghosal, Tanmay Mandal, Amlan K. Roy
We present a purely numerical approach in Cartesian grid, for efficient computation of Hartree-Fock (HF) exchange contribution in the HF and density functional theory models. This…
Quantum Restoration of Broken Symmetry in one Dimensional Loop Space
Pinaki Patra, Tanmay Mandal, Jyoti Prasad Saha
For 1 Dimensional loop space, a nonlinear nonlocal transformation of fields is given to make the action of the self-interacting quantum field to the free one. A specific type of Cl…
