Title:Seeing the ‘impossible’: Imaging the magnetic realm using diamond quantum magnetometry
Date: December 28, 2023, 16:40
Location:Cinema Hall
Abstract: A common theme in the study of magnetic materials is the ever-reducing spatial and magneticfootprints which promise novel properties at reduced dimensions and the miniaturization of technology. Supporting this research progress is the timely development of diamond-based quantum sensing which provides the desired combination of field sensitivity, spatial resolution and ambient operation. I will cover recent uses of quantum sensing to explore non-trivial spin textures in thin magnetic films, down to an atomic layer. One intriguing insight enabled by quantum sensing includes the ability to read out the vorticity of merons, antiferromagnetic textures, which reveal their nature as emergent magnetic charges. I will provide directions for possible developments of other quantum sensing platforms for the exploration of magnetic phenomena in low dimensional systems.
Bio: Mete Atatüre received his Bachelor of Science degree in 1996 from Bilkent University Physics Department in Turkey. He joined the Quantum Imaging Laboratory at Boston University for his PhD. From 2002 to 2007, he worked as a Postdoctoral Fellow in the Quantum Photonics Group at ETH Zurich. He joined the Cavendish Laboratory in June 2007 as a University Lecturer, becoming a Reader in 2011 before being promoted to a Professorship in 2015. He is the scientific lead of the Quantum Optical Materials and Systems team (QOMS). His experimental research group investigates the quantum physics of light-matter interaction to implement quantum information networks and communication, as well as new applications in sensing. He is also a co founder and CSO of quantum-tech spin out, Nu Quantum Ltd. He dedicates significant time to science communication and public engagement on the role of science in society, scientific integrity, and achieving diversity & equality in science. Mete Atatüre is a Fellow of the Institute of Physics, the Optical Society of America, Academia Europaea, and the Turkish Science Academy. He is the recipient of the IoP 2020 Thomas Young Medal. He became the head of the Cavendish Laboratory in October 2023.
