# CE-TDDFT

This is a real time TDDFT code for Quantum-Espresso.

### News

* Feb 20, 2019: **(experimental)** electron wavepacket

* Feb 18, 2019: save time dependent charge density

* Feb 17, 2019: Ehrenfest dynamics implemented

* Nov 26, 2018: ce-tddft is now compatible with QE-6.3

* Jul 17, 2017: ce-tddft is now compatible with QE-6.1

## Features

* Optical absorption spectrum of molecules

* Ehrenfest dynamics, norm-conserving only

## Authors and contributors

D. Ceresoli, X. Qian, A. Genova, A. Krisihtal, M. Pavanello

## Build instructions:

### From Quantum-Espresso distribution

not available yet!

### Stand-alone 

1. Configure and compile QE as usual, then:

2. ```git clone https://github.com/dceresoli/ce-tddft.git```

3. ```cd ce-tddft```

4. ```./configure --with-qe-source="QE folder containing make.inc"```

5. ```make```

### Source releases

Official source releases are found [here](https://github.com/dceresoli/ce-tddft/releases).

### TODO

- Ehrenfest dynamics with USPP and PAW pseudos

- arbitrary pulses

- improve performance of NL-terms in circular dichroism

- restart/checkpointing

- in-memory evolution for molecules

- projection over AO's

- integrators: taylor-n, cranck-nichoson-2

- spin-orbit

- periodic crystals
