LBNL-AMO-MCTDHF is an open-source code for solving the time-dependent Schrödinger equation for atoms and molecules under heavy fire from intense laser pulses. 

It is funded by the U.S. Department of Energy, mostly by the Early Career Program.

LBNL-AMO-MCTDHF uses several EXPOKIT routines to power the integration

of the nonlinear differential equations of MCTDHF.


LBNL-AMO-MCTDHF is both inspired by and guided by the open-source

implementation of MCTDH of H.-D. Meyer et al. at Heidelberg.


The 3rd cousin to MCTDH and MCTDHF is MCTDHB, developed by

Alon, Streltsov, Cederbaum and others, available with a modern cross-platform frontend MCTDHB-lab (Streltsov & Streltsova).
