Relaxation Between Bright Optical Wannier Excitons in Perovskite Solar Absorber CHNHPbI
Ravindra Nanguneri, John Parkhill
We study the light-absorbing states of the mixed-halide perovskite CHNHPbICl and tri-iodide perovskite CHNHPbI with density functional and many-body…

How Electronic Dynamics with Pauli Exclusion Produces Fermi-Dirac Statistics
Triet Nguyen, Ravindra Nanguneri, John Parkhill
It is important that any dynamics method approaches the correct population distribution at long times. In this paper, we derive a one-body reduced density matrix dynamics for elect…

Anisotropic Multipolar Exchange Interactions in Systems with Strong Spin-Orbit Coupling
Shu-Ting Pi, Ravindra Nanguneri, Sergey Savrasov
We introduce a theoretical framework for computaions of anisotropic multipolar exchange interactions found in many spin--orbit coupled magnetic systems and propose a method to extr…
