Quantum Nanophotonics

I am researcher in the Quantum NanoPhotonics group of Prof. Dr. Val Zwiller at KTH in Stockholm. On this website you can find my CV, publications, research interests, and contact details. You can find my publications and citations also at Google Scholar.

I have Master and Bachelor student projects on excitonic superfluids and Bose-Einstein condensation and on single-photon detectors. Projects may include experiments at ultralow temperatures in a dilution refrigerator, spectroscopy with continuous and pulsed lasers, sample preparation and nanofabrication, and theoretical modelling, depending on the student's interest and availability. Interested students are welcome to inquire about possible projects:


Excitonic superfluids and Bose-Einstein condensation

Students interested in a project on excitonic superfluids are welcome to contact me. I received a Starting Grant from the Swedish Research Council and funding from the ADOPT Centre for my research on excitonic superfluids. 


Loophole-free Bell test

From May 2014 until October 2015 I worked in the group of Prof. Dr. Anton Zeilinger in Vienna. There we performed a loophole-free Bell test with quantum entangled photons. We addressed the detection loophole, the locality loophole and the freedom-of-choice loophole in one experiment. Therefore, our experiment shows in a most conclusive way that physical objects do not have measurable properties before these properties are actually measured, or that there exist physical interactions that go faster than light. Read our article in PRL (open access).

This publication was awarded the Paul Ehrenfest Best Paper Award for Quantum Foundations for the year 2015! It was also awarded the Best Paper Award of the Austrian Academy of Science (ÖAW) from the Jubiläumsfonds der Stadt Wien.
