Relaxation Between Bright Optical Wannier Excitons in Perovskite Solar Absorber CH $_{3}$ NH $_{3}$ PbI $_{3}$

Ravindra Nanguneri, John Parkhill

We study the light-absorbing states of the mixed-halide perovskite CH $_{3}$ NH $_{3}$ PbI $_{2}$ Cl and tri-iodide perovskite CH $_{3}$ NH $_{3}$ PbI $_{3}$ 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…
