Scientific activity

Our team studies the different electronic states of quantum matter in both 2D and 3D materials. We strive to understand how quantum interactions and correlations between electrons modify the propagation of electric and thermal currents. The team’s activities can be broken down into 2 complementary approaches.

The first is the development of a quantum local probe microscope, which can probe, at low temperature, many properties of quantum materials and quantum circuits on the scale of a few nanometers. The quantum detector is a SQUID deposited at the end of a fine quartz tip, which is scanned onto the surface of a sample. The SQUID can be used as a magnetometer, a thermometer, an atomic force microscope probe, or as a metal tip generating a local electric field for local grid microscopy.

The second approach involves the study of new quantum materials using charge transport and entropy measurements. The materials studied range from unconventional superconductors, such as cuprates or dilute metals, to quantum magnets of the Mn3X type, via Weyl semimetals.
