Led by Dominique Laroche · Physics
What we study
The Laroche Lab studies how tiny devices made of materials like GaAs/AlGaAs and InAs nanowires interact at the nanoscale. They use ultra-cold temperatures and magnetic fields to measure how electrons move in one-dimensional systems, which could help future quantum computing.

Current projects
Coulomb drag between coupled 1D systems
Measuring how current in one quantum wire affects another nearby wire through Coulomb interactions.
Project Towards Cryogenic Noise Thermometry in Nanostructures
The lab studies how to measure the temperature of tiny devices at very low temperatures. Students use lock‑in amplifiers and a Python program to sweep frequencies and read noise from resistors. They compare the measured temperatures to known values at room temperature and liquid nitrogen temperature.
