TEBDOL is a program for calculating time evolution of ultracold atoms in 1D and 2D optical lattices. It is based on tree tensor networks states (TTNS) and uses a generalization of the time-evolving block decimation (TEBD) algorithm. Simulation of 1D models is parallelized using Message Passing Interface (MPI). TEBDOL is written in Common Lisp.
