Non-exponential decay of a giant artificial atom

Scientific Background

I hold a Master’s degree in condensed matter physics from Technische Universität München. My thesis work was carried out at the Walther-Meißner-Institut in Garching, focusing on transmon qubits coupled to superconducting 3D cavities.

Current Research Topic

I recently joined the Quantum Device Physics laboratory at Chalmers to study the interaction of surface acoustic waves (SAW) with superconducting qubits. By exploiting the short wavelength and slow propagation velocity of SAW, artificial atoms can be designed that couple to a propagating field at two distant points such that the SAW travel time between them has to be taken into account. In my PhD work I will investigate the non-exponential decay and phonon scattering properties of such a “giant atom” system.
