Patrick Maletinsky was born in 1979 in Baden, AG and grew up in the town of Schaffhausen, Switzerland. He studied Physics at ETH Zurich with stays at the Ecole Normale Supérieure Paris and at JILA in Boulder, Colorado. For his doctoral studies, he returned to ETH Zurich, where he graduated under the supervision of Prof. Atac Imamoglu on optical studies of hyperfine-interactions in individual, self-assembled quantum dots. His doctoral thesis was awarded the Schläfli-prize of the Swiss Academy of Sciences in 2010. From 2008 to 2011, he was a postdoc in the group of Amir Yacoby at Harvard University, where he developed and applied novel, highly precise methods for nanoscale magnetic field sensing. In 2012, Patrick Maletinsky assumed the Georg-H.-Endress-Professorship as an Assistant Professor at the Department of Physics of the University of Basel; he was promoted to Associate Professor in February 2017.
Our research is centered around developing novel sensory tools based on individual quantum systems and on applying these sensors to scientific problems, where more conventional techniques are reaching their limits. The prime example for such sensing systems is a single electron spin, which can be used to image magnetic fields with nanoscale spatial resolution. Our group focusses on applying such techniques to problems in condensed matter physics with a particular focus on mesoscopic systems.
At the moment, the workhorse for our experiments is the Nitrogen-Vacancy (NV) color center in diamond. Over the last decade, NV centers have been established as robust spin systems, which can be coherently manipulated and efficiently read-out using microwave and optical fields. Since these properties are preserved even at room temperature, NV centers form an attractive candidate system for quantum sensing in various environments. Our experiments will thus range from room-temperature studies of non-trivial magnetic structures (such as magnetic vortices) to explorations of exotic electronic states (such as quantum Hall effects) in cryogenic environments.
