Optical excitation from anti-causally corrected real-time dynamics in a minimal basis

Joydev De, Manoar Hossain, Joydeep Bhattacharjee

Here we demonstrate workably accurate estimation of optical excitation threshold for large systems comprising of hundreds of atoms through an anti-causally corrected(ACC) real-time…

Maximally valent orbitals in systems with non-ideal bond-angles

Joydev De, Sujith N S, Manoar Hossain +1

In pursuit of a minimal basis for systems with non-ideal bond angles, in this work we try to pinpoint the exact orientation of the major overlapping orbitals along the nearest neig…

Self-energy corrected tight binding parameters for few p-block semiconductors in the hybridized atomic orbital basis constructed from first principles

Manoar Hossain, Joydeep Bhattacharjee

We present self-energy corrected tight-binging(TB) parameters in the basis of the directed hybridised atomic orbitals constructed from first principles, for nano-diamonds as well a…

Hybrid atomic orbital basis from first principles: Bottom-up mapping of self-energy correction to large covalent systems

Manoar Hossain, Joydev De, Joydeep Bhattacharjee

Construction of hybrid atomic orbitals is proposed as the approximate common eigen states of finite first moment matrices. Their hybridization and orientation can be a-priori tunne…

Transferability of self-energy correction in tight-binding basis constructed from first principles

Manoar Hossain, Joydeep Bhattacharjee

We demonstrate in this work the transferability of self-energy(SE) correction(SEC) of Kohn-Sham(KS) single particle states from smaller to larger systems, when mapped through local…

Hybrid superlattices of graphene and hexagonal boron nitride: A ferromagnetic semiconductor at room temperature

Rita Maji, Joydeep Bhattacharjee

Carbon (C) doped hexagonal boron nitride (hBN) has been experimentally reported to be ferromagnetic at room temperature. Substitution by C in hBN has been also reported to form isl…
