| Description | Developed a quantum Monte Carlo computer code. |
| Exploitation Route | They will be able to use a better computer code, and perform calculations with fewer computational resources |
| Sectors | Education,Electronics,Energy,Environment,Other |
| Description | Improved computer code have made its usage easier, and it has saved significant amount of computer time |
| Sector | Other |
| Impact Types | Cultural |
| Title | PHON - A program to calculate phonons using the small displacement method |
| Description | I am not entirely sure if this is relevant, but here it is. The PHON code is a computer software that is used to compute vibrational frequencies of materials, and with them also compute their thermodynamic properties. The programme is freely available from my personal web-page, and also from Github and from the Computer Physics Communications website. |
| Type Of Material | Improvements to research infrastructure |
| Year Produced | 2009 |
| Provided To Others? | Yes |
| Impact | PHON is used by hundreds of groups worldwide, and the describing paper (Computer Physics Communication 180, 2622-2633 (2009)) has been already cited more than 400 times. I am associating this product with all my grants as I have been developing this code over the years, and so all my grants have contributed to sustain this development. |
