Due to the large number of posts recently, there is currently a delay of several weeks between posts being submitted and the corresponding emails being distributed to all users. Please bear with us while we try to improve this. In the meantime – and until this notice is removed – it would assist us considerably if you could submit only important and/or urgent posts and thus help to reduce the size of the mail queue. Under no circumstances should you resend posts multiple times when you find the emails are not distributed immediately.

In light of the Russian military offensive in Ukraine, we request that announcements relating to events, jobs and other activities associated with institutions supported by the Russian and Belarusian states are not posted to the Psi-k forum.

PhD position: Multi-reference quasi-particles fo ... (No replies)

Strong correlation effects, i.e., cooperative behavior that cannot be predicted from the properties of individual electrons, are responsible for a variety of non-trivial or 'exotic' electronic properties of materials.  However, the description, comprehension, and prediction of the effects of electron correlation in real systems, is still one of the greatest challenges in physics.  

 

This PhD project proposes to tackle the problem of describing strong electron correlation by combining two different, yet complementary, approaches: a condensed matter description based on quasi-particles and a quantum chemistry description based on multi-reference wave functions, hence contemplating the concept of “multi-reference quasi-particles”. During the course of the project, we propose to i) set the foundation for this new approach; ii) test the idea on simple and exactly solvable models such as the Hubbard model; iii) apply this new paradigm to real materials, such as bulk NiO. 

 

This project has received financial support from the French Scientific Research National Center (CNRS) through the 80|Prime program.  It will be carried out at the Laboratoire de Physique Théorique and in collaboration with the Laboratoire of Chimie and Physique Quantiques in Toulouse starting from September/October 2020. 

 

Due to the multi-disciplinary nature of the project, we encourage applications from students with a solid background in Physics, Chemistry and/or Mathematics and it is desirable that he/she is familiar with electronic structure theory and programming. During the course of this PhD project, the student will become comfortable with state-of-the-art electronic structure methods as well as simple mathematical models. He/she will also gain valuable experience in both computer algebra systems (such as MATHEMATICA) and high performance computing (HPC).

 

Interested applicants are encouraged to apply via email to Pina Romaniello ([email protected]) and/or Pierre-François Loos ([email protected]).

 

Please include a letter of motivation, a CV with a list of publications, and the contact information of two academic references.
The review of applications begins immediately. 
Applications are accepted until the position is filled.
