Hi Everyone,
This Friday at 2pm in the Division room Joon will be giving group
meeting. An abstract of Joon's talk is below. See you there!

"Exponential time propagators for large exciton systems"
Joonsuk Huh
In solving the time-dependent Schrödinger equation, one usually needs
to compute or approximate an exponential of Hamiltonian matrix
in a finite basis set as a corresponding time propagator. As the
system size increases, this matrix function becomes more difficult to
be evaluated exactly within a finite numerical precision and this gives
limitations on the time step size and the total time length for the
time propagation.
To see the long time behaviour of wave functions for the large
systems, efficient methods for the matrix exponential are demanding.
In my group meeting talk, I will explain the evaluation of the
exponential time propagator aiming for the photosynthetic roll and
baseplate system in the exciton basis.
