A post-doctoral position in the area of theoretical condensed-matter physics is open

for a young researcher in the Laboratoire des Solides Irradiés (LSI), École

Polytechnique, Palaiseau, France.

Nitrogen-vacancy centers in diamond are used at ambient T as magnetic sensors on

the nanometer-scale and, since recently, at high pressure (P) to detect pressureinduced

superconductivity. The project aims at understanding, via ab initio calculations

and the modeling of electronic correlations, the effect of non-hydrostatic components

of the stress tensor on the symmetry and values of the energy levels of the N-V center

in diamond when used in the anvil of a diamond anvil cell used to apply high pressures.

Electronic correlations will be modeled through the extension of Hubbard’s model for

many-body states. A part of code development and numerical implementation is to be

expected. One body states will be obtained through simulations performed within the

Density Functional Theory (DFT) with the QUANTUM ESPRESSO package.

The post-doctoral contract will last 16 months, starting at fall 2021. The post-doc is

funded by CEA, the Commissariat à l’Énergie Atomique et aux Énergies Alternatives

(http://www.cea.fr). The post-doctoral contract is required to start less than two years after

the date of the PhD defense.

The post-doctoral researcher will work in collaboration with theoreticians Nathalie Vast

and Jelena Sjakste (LSI), as well as with Yeonsoo CHO (PhD student). A collaboration

with experimentalists of the ANR project is also part of the project.

Ideally, the candidate has a doctoral degree in mathematical physics for condensed

matter, a deep understanding of what electronic correlations are, and some experience

in ab initio simulations within DFT. An experience in code development is required.

For further information about the project, please contact questions to

Nathalie Vast ([email protected]).

To apply for this position, please send your CV, list of publications and motivation letter

to Nathalie Vast. Please mention the contact details of three reference persons in your

application.

The deadline for application is 30th August 2021.
