Postdoctoral fellowship in Engineering and Thermodynamics of Correlated Quantum Systems

The Quantum Physics in Circuits lab (QPC, C2N, Paris-Saclay university) is offering a post-doctoral position of two years, renewable, in a stimulating, state-of-the-art environment. We are seeking for a dynamic young experimentalist with a solid research background in quantum physics. A PhD or previous post-doctoral experience in the field of mesoscopic physics would be an asset.

The project is to engineer correlated quantum states in tunable circuits, and to investigate their salient features through revealing thermodynamic observables. One primary objective is to perform an unequivocal observation of Majorana modes, through their fractional entropy. The project is supported by an ERC synergy grant (Quantropy, 07/2021-06/2027).

The research work will be conducted at the Center for Nanoscience and Nanotechnology in the Paris-Saclay University, together with a team including two PhD students, one research engineer and two physicists. It will benefit from the support of synergy partners in Canada, Israel and Switzerland, as well as from the additional theory support of a strong network of collaborators. The postdoctoral fellow will have at his disposal state-of-the-art measurement setups and a direct access to the well-equipped C2N cleanroom. The QCP lab notably operates one cryofree dilution refrigerator of base electronic temperature 6mK including homemade cryogenic amplifiers for ultra-sensitive noise measurements, and a second sub-5mK cryofree dilution refrigerator is planned for delivery.

The starting date can be as soon as possible.  The net salary is between 2.6k€/month and 3.3k€/month depending on research experience.

Inquiries and applications (including a CV) should be sent to Frédéric PIERRE (frederic.pierre@c2n.upsaclay.fr) and Anne ANTHORE (anne.anthore@c2n.upsaclay.fr).

Postdoctoral position in Thermodynamics of 2DEGs

We have an opening for a two-year postdoctoral position, for work in a collaboration between C2N, Institut Néel and the Grenoble High Magnetic Field Laboratory within the ANR project THERMES2D. The aim of the project is to explore correlated phases of matter through innovative thermodynamic measurements, such as heat capacity and entropy.

The successful candidate will join the group “Physics and Technology of Nanostructure and Quantum Systems” in the team of Ulf Gennser. The central part of his/her work will be to develop novel, thermodynamic tools based on GaAs/AlGaAs 2-dimensional electron gases (2DEGs), which will be applied to investigating the specific heat in the fractional quantum Hall effect. She/he will be highly involved in the fabrication and measurements of membrane 2DEGs using the nano fabrication facilities of C2N.

QUALIFICATIONS AND EXPERIENCE:

Candidates should hold a Ph.D. in experimental condensed matter physics or equivalent. A good technical background in semiconductor sample processing is crucial (e-beam lithography, lift-off techniques, etch techniques …). Experience with transport experiments, low-temperature experiments, as well as a knowledge in mesoscopic physics and 2-dimensional electron gases would
be appreciated assets.

Applications (CV + two letters of recommendation + short research summary) should be sent by email to ulf.gennser@c2n.upsaclay.fr

Student positions

The group Phynano is always seeking for highly motivated undergraduates and graduate students (master and PhD level). Candidates are invited to look in the different research project of the group and contact the principal investigators (please attach a short CV including the names and e-mail addresses of two references). 

Open positions:

Permanent CNRS research positions

The CNRS opens permanent researcher positions in Phynano's field of interest (CNRS section 03, "Condensed matter physics: structures and electronic properties") at the end of each year. You can find all the information here. Although not officially required, the candidates are strongly advised to contact the group leader before applying.
