Welcome to lime’s documentation!

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

Check docs/manual.pdf for documentations.

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
