The goal is to provide a simple-to-use package to study how light interacts with matter.

Main modules
# Nonlinear molecular spectroscopy * sum-of-states for multilevel system
Pros: computationally cheap Cons: decay is introduced phenomelogically; pure dephasing cannot be addressed
- correlation function approach -- Direct computing the many-point correlation functions with the quantum regression theorem
Valid for open quantum systems where environment effects can be rigirously described with open quantum system techniques.
Visulize with double-sided Feynman diagrams instead of the time-loop diagrams.
- non-perturbative approah -- valid for ALL systems provided the quantum dynamics can be compuated
Simulating the laser-driven dynamics including explicitly all laser pulses
# Molecular quantum dynamics - Adiabatic wavepacket dynamics -- Split-operator method -- Discrete variable representation
- Nonadiabatic wavepacket dynamics -- Split-operator method
For the exact nonadiabatic dynamics of vibronic models in the diabatic representation.
# Semiclassical quantum trajectory method
# Quantum chemistry
# Open quantum systems - Lindblad quantum master equation - Redfield theory - second-order time-convolutionless master equation - hierarchical equation of motion
# Quantum transport - Landauer transport
# Soid state materials - Band structure from tight-binding Hamiltonians
# Periodically driven matter - Floquet spectrum
# Others - Schmidt decomposition
