Theory Underpinning Quantics

What is MCTDH?

Originally developed to use the Multi-Configuration Time-Dependent Hartree (MCTDH) method for solving the Time-Dependent Schrödinger Equation (TDSE), Quantics has evolved into a versatile platform. It now encompasses a wide array of powerful techniques derived from MCTDH capable of simulating and analysing quantum dynamics.



The Heidelberg MCTDH package is still available on request. More information on this can be found on the website

The Theory behind Quantics

Prof. Graham Worth

An overview of the theory behind some of the capabilities of Quantics, and how the different methods can be derived

A more in depth look at the theory behind some of the methods implemented in Quantics can be found in these notes by Prof. Hans-Dieter Meyer.
