Rossier Group
The Rossier Group explores the electronic and spin properties of quantum systems engineered with atomic-scale precision. They are primarily driven by a deep curiosity to understand fundamental open questions in quantum mechanics and many-body physics. At the same time, their research holds significant potential to address the challenges faced by the electronics industry in continuing the miniaturization of devices and enabling a new technological revolution based on quantum technologies. Their work places strong emphasis on Quantum Nanostructures, investigating how atomic-level control can give rise to novel quantum phenomena. They rely extensively on model Hamiltonians, frequently apply non-equilibrium quantum dynamics and quantum transport simulations, and occasionally make use of density functional theory (DFT) calculations.
In recent years, their research has focused on two main areas: atomic-scale quantum electronics and the electronic properties of 2D materials. Both topics are tightly connected to the design and exploration of Quantum Nanostructures, which play a central role in advancing fundamental understanding and developing next-generation quantum technologies.
