Quantum Magnetic Sensors for Axion Dark Matter Search

We are building a precision optical magnetometer based on quantum sensors to search for a possible effectively magnetic signature from an axion particle as a candidate for the dark matter.

This research is funded by the TÜBİTAK 2232-B International Young Researchers Program. Project title: "Searching for new particles with laboratory-scale experiments using quantum magnetic sensors", funded from December 2023 to December 2026, total budget: 4,905,000 TL.

Zero-field NMR with Optical Magnetometers

We are building an optical magnetometer that works at room temperature under zero external magnetic field to measure Nuclear Magnetic Resonance signal from various chemical samples.



Group Leader: Prof. Aybas

Deniz Aybaş Tümtürk is an Assistant Professor of Physics at Bilkent University. Prior to joining Bilkent, she was a Postdoctoral Scholar at the University of California at Berkeley for two years.

Asaf Toprakçı
Senior undergraduate student in Physics

Asaf is interested in the experiments investigating the intersection of quantum information science, quantum many-body physics and quantum sensing. As a part of Aybas Lab, he is currently developing a data analysis algorithm that will search for topological defects of axions or axion-like particles such as axion stars or domain walls, employing artificial neural networks. In his free time, he enjoys making music and going to concerts.
