Welcome to Tomasz Smoleński's webpage

I work as a post-doc in the Quantum Photonics Group of prof. Atac Imamoglu at ETH Zurich. My current research activity is mainly focused on optical studies of monolayers of transition metal dichalcogenides. 

In January 2018 I obtained the PhD degree at Faculty of Physics, University of Warsaw. The thesis was related to magneto-optical studies of semiconductor nanostructures, namely the quantum dots doped with single transition metal ions, which I carried out in the Laboratory of Ultrafast Magneto-Spectroscopy LUMS.

Research Highlights

Magnetic ground state of an individual Fe2+ ion in strained semiconductor nanostructure


The iron Fe2+ atom embedded in a semiconductor exhibits a single non-degenerate ground state of zero magnetic moment. Here we show that by using sufficiently large strain it is possible to tailor the energy spectrum of the iron atom to obtain doubly degenerate (magnetic) ground state, which can be utilized for storage and processing of the quantum information.

Tuning Valley Polarization in a WSe2 Monolayer with a Tiny Magnetic Field


The electron-hole pairs in monolayers of transition metal dichalcogenides exhibit a novel degree of freedom, so called valley pseudospin, that might be exploited to store the quantum information. Here we show that dark excitons can store the information on their valley pseudospin for orders of magnitude longer than previously studied bright excitons in a WSe2 monolayer.
