Short Biography

Dominik Zumbühl, born 1974 in Zürich, received a diploma in physics in 1998 from ETH Zürich. Subsequently, he started working on his doctorate in mesoscopic physics at Stanford University in the lab of Prof. Charles Marcus. In 2000, Dominik relocated together with Dr. Marcus's group to Harvard University, where, in 2004, he obtained a Ph. D. with the title "Coherence and Spin in GaAs Quantum Dots". He then joined the group of Prof. Marc Kastner at MIT as a postdoctoral fellow. In April 2006, Dominik was appointed as a tenure track assistant professor at the Department of Physics at the University of Basel.

In 2008, Dominik was among the first series of recipients of the prestigious Starting Grant of the European Research Council (ERC), adding significantly to research funding over a five year period. press release, more info here.



Research Summary

Research focuses on nanoscale physics, quantum coherence, spin and electron interactions in semiconductor nanostructures. Ongoing projects includes research on spin qubits in coupled, laterally gated GaAs quantum dots, topological quantum phases in the fractional quantum Hall effect and other experiments investigating mesoscopic electron transport. We are interested in coherent manipulation of quantum mechanical degrees of freedom in solid state nanostructures, with the goal of implementing quantum computation schemes.

Experiments investigate quantum transport through semiconductor nanostructures which are fabricated in-house using high-mobility 2D electron gas materials obtained from collaborating molecular beam epitaxy labs. Experiments are typically performed in dilution refrigerators at millikelvin temperatures in magnetic fields. Measurements are done using electronic low-noise techniques and may involve nanosecond-pulsing and microsecond readout schemes.
