Post-Doctoral Researcher – Quantum Computing & Non-Equilibrium Many-Body Dynamics

The Theory Team at IJCLab (Université Paris-Saclay, France) invites applications for a two-year postdoctoral position under the supervision of Dr. Denis Lacroix. The successful candidate will develop and benchmark innovative quantum algorithms for interacting many-body systems, comparing them with leading classical techniques (e.g., matrix-product states and our team’s phase-space approach). Research will encompass both real- and imaginary-time methods to access ground states, excited states, and far-from-equilibrium dynamics, as well as the study of entanglement via von Neumann entropy and measures of “quantum magic.”

Key Responsibilities:
-Algorithm Design & Implementation: Create efficient quantum circuits and numerical prototypes, with pilot applications in nuclear physics, neutrino dynamics, and condensed-matter systems.
-Entanglement Analysis: Develop and apply novel diagnostics to track entanglement growth and quantum resources.
-Team Collaboration & Mentorship: Coordinate activities within the quantum-computing group, contribute to PhD projects, and co-supervise Master’s internships.

Candidate Profile:
-PhD in Physics, Computer Science, Applied Mathematics, or related fields, with a strong background in quantum information or many-body theory.
-Proficiency in scientific programming (Python, Julia, C++, etc.) and experience with tensor-network or phase-space methods.
-Excellent communication skills in English.

Apply & Inquiries:
If you have any questions, please contact Denis Lacroix (lacroix@ijclab.in2p3.fr).

Apply online via the CNRS portal: https://emploi.cnrs.fr/Offres/CDD/UMR9012-HINBEN-009/Default.aspx

Applications will be reviewed on a rolling basis. We look forward to your contribution to cutting-edge quantum-many-body research!

Applicants must have a PhD in theoretical physics or a related field completed before the start date of the postdoctoral position. Preference will be made for candidates with no more than 4 years of postdoctoral experience. The candidates will be selected according to their proximity to the project. Knowledge in numerical methods and computer languages, such as Python, C, or Fortran95, will also be appreciated. Any question about the position may be sent to Jérôme Margueron (jerome.margueron@cnrs.fr).

The position will start in September 2025.

PhD fellowship in nuclear theory at The nuclear-astrophysics group at ULB (Brussels, Belgium)

The nuclear-astrophysics group at ULB (Brussels, Belgium) is opening a four-year PhD fellowship in nuclear theory. The project aims to equip large scale models of nuclear structure with quantified (parameter) uncertainties, utilizing the recent progress in machine learning techniques to offset the computational cost of standard approaches.

Interested candidates can find more detailed information in the official job announcement (link) https://euraxess.ec.europa.eu/jobs/331014.

We believe that joining the ULB nuclear astrophysics group constitutes an excellent opportunity for early career scientists today. Our team consists both of experienced researchers with international renown and a large number of motivated young scientists, creating an atmosphere that is both dynamic and friendly. We collaborate with several theory and experimental groups in both nuclear physics and astrophysics, in Belgium and abroad.

We encourage interested candidates to reach out as soon as possible to Dr. W. Ryssens (wouter.ryssens@ulb.be).

Applied Nuclear Theory Postdoctoral Position at LANL

Los Alamos National Laboratory has an open position for an applied nuclear theory postdoc in the T-2 group, https://jobsp1.lanl.gov/OA_HTML/OA.jsp?OAFunc=IRC_VIS_VAC_DISPLAY&OAMC=R&p_svid=136413&p_spid=6204442&p_lang_code=US

The T-2 group (Nuclear and Particle Physics, Astrophysics and Cosmology) in the Theoretical Division at Los Alamos National Laboratory invites applications for one postdoctoral position in theoretical modeling of nuclear reactions and nuclear data evaluations, to begin in the Fall of 2025. Candidates are expected to have obtained a PhD in Physics or closely related field by the beginning of the postdoctoral appointment (within five years of receiving their PhD; exceptions to the five-year cutoff can be made for sufficiently extenuating circumstances). This appointment is for two years. Extension for a third year may be considered, contingent on performance and funding.

The applied nuclear theory group has seven staff members. We conduct research on a broad set of topics, including developing phenomenological and microscopic models of nuclear reactions, nuclear data evaluations and uncertainty quantification, nuclear many-body theory, and high performance/quantum computing with applications in basic science (nuclear astrophysics and cosmology), nuclear energy (fusion and fission) and nuclear safety and security. The group also actively engages in collaborations with theorists and experimentalists at LANL and worldwide.

Interested applicants should submit their application (CV, research statement) and arrange for three letters of recommendation to be sent by email (t2-pdsearch-2025@lanl.gov) by June 6, 2025, for full consideration.

The successful candidate will:

• Gain experience in theoretical and computational modeling of nuclear reaction and/or structure physics
• Publish research in leading scientific journals
• Develop strong programming skills
• Work both independently and in a team environment to solve problems in support of Laboratory missions

Two postdoctoral positions within the TARDIS collaboration at MSU

Numerical modeling of astrophysical transients with the open-science TARDIS collaboration
The TARDIS Radiative Transfer Group at Michigan State University invites applications for postdoctoral positions to model astrophysical transients using the open-science Monte Carlo radiative-transfer framework, TARDIS. While some responsibilities include extending the TARDIS code, the primary focus is on conducting research with the code to analyze observational data and publish results.

We are seeking candidates for two research areas:
1. Common Envelope Events in Binary Star Systems: Utilize TARDIS to post-process hydrodynamic simulations and generate synthetic spectra for these events.
2. Late-Phase Type Ia Supernova Studies: Analyze nebular spectroscopy and light curves, enhance microphysics in TARDIS, and compare findings with recent spectral data.

Candidates must hold a Ph.D. in astronomy, physics, or a related field by the appointment start date (no later than Fall 2025). Applications from underrepresented groups are strongly encouraged. Experience with radiative transfer methods is a plus but not required. A background in open-source software development and open science is particularly valued.
These positions offer professional development opportunities in leadership, mentoring, paper and grant writing, presentations, and networking. Successful applicants will contribute to the TARDIS framework and are expected to lead the publication of research results.

To apply, please submit a brief cover letter describing your interest in the position and any proposed research projects using TARDIS, a curriculum vitae including your thesis title, publication list, mentorship experience, and contributions to open science (if applicable), and contact information for three references (letters will be requested later). For full consideration, apply by October 31; however, the positions will remain open until filled. Applications must be submitted through the MSU hiring website: MSU Careers – Job Posting 927629. Please ignore any incorrect dates on the application form.
For more information about the TARDIS group and our collaborative efforts, visit the TARDIS website and the Kerzendorf Lab at MSU.
