Interplay between Electronic Topological Transitions and Thermodynamics – IET³ 

Within the collaborative project between LNCMI Grenoble and PHELIQS laboratories to use the newly developed magnetization technique as a complement to the different well-established quantum oscillations probes (resistivity, Hall effect, thermoelectric power, and torque) to study the interplay of field induced Fermi surface instabilities and thermodynamics, the co-supervised PhD will be involved in the characterization measurements (resistivity, thermoelectric power, specific heat, magnetization ...) at very low temperature (Pheliqs) and high magnetic field (LNCMI Grenoble), data analysis, and improving the experimental devices. In addition to the 2 supervisors, the PhD student will also collaborate with other researchers in both laboratories doing complementary measurements on these compounds. If necessary, some measurements may be extended up to higher fields (60 or 90T) at LNCMI Toulouse (pulsed field facility).

It is also considered giving the student (if she/he is interested) the unique opportunity to synthesize her/his own single crystals because Pheliqs laboratory has a very performing crystal growth team.

Investigation of strongly correlated electron systems by quantum-oscillation measurements

The PhD project is dedicated to quantum-oscillation studies of strongly correlated electron systems in high magnetic fields. Such measurements are the tool-of-choice for the determination of the Fermi-surface topology in metals. In strongly correlated electron systems, high magnetic fields are usually required to observe quantum oscillations. In addition, high magnetic fields often induce electronic phase transitions. Among them are quantum phase transitions, i.e., continues zero temperature phase transitions, around which new quantum phases are expected to emerge. Theoretically, such phase transitions are often accompanied by a Fermi-surface reconstruction. This is one of the key questions that will be addressed experimentally within this PhD project. The student will have a unique opportunity to use state-of-the-art high-field facilities of the European Magnetic Field Laboratory. This includes steady fields to 36 T and beyond available in Grenoble, France and Nijmegen, the Netherlands, as well as pulsed fields beyond to 70 T and higher in Dresden, Germany. All the measurements will be performed at low temperatures. This PhD project is part of a larger French-German collaboration, within which the student will be in contact with theoreticians, who will provide band-structure calculations to be compared with the experiment.

The thesis will be financed by the joint French-German ANR-DFG grant “FermiNESt”. The PhD student will be jointly supervised by Dr. I. Sheikin from LNCMI, CNRS, Grenoble, France and Prof. J. Wosnitza from HLD, HZDR, Dresden, Germany.
