Researchers Aljaž Kavčič, dr. Maja Garvas, Matevž Marinčič and doc. dr. Matjaž Humar from the F5 department and dr. Boris Majaron from the F7 department of the Jožef Stefan Institute have, in collaboration with researchers from Graz University, published a paper in Nature Communications entitled Deep tissue localization and sensing using optical microcavity probes. In the paper they presented a new method for imaging through scattering tissues, based on localization of whispering gallery mode microresonators with spectrally narrow emission that enables a decomposition of diffuse signal into contributions from individual microresonators. The developed method combines the ability of precise localization on cellular level with possibility of sensing various parameters such as temperature, pH and refractive index, which makes it a versatile and promising tool in the field of deep-tissue imaging. First author of the paper Aljaž Kavčič presented the results of this work in his master’s thesis, for which he was awarded »Prešernova nagrada« of University of Ljubljana.

Associates of the Department of Condensed Matter Physics Tina Arh, Matej Pregelj, pHD, and prof. Andrej Zorko pHD, discovered the first realization of a quantum spin liquid on a Ising triangular-lattice antiferromagnet. They performed a large scale experimental study in collaboration with the researchers from the Slovenian Institute of Mathematics, Physics and Mechanics as well as researchers from India, Great Britain, France and the USA. The results were published in Nature Materials in the article The Ising triangular-lattice antiferromagnet neodymium heptatantalate as a quantum spin liquid candidate. In addition to being a significant scientific discovery, this discovery also has an important potential for the latest quantum technologies, as spin liquids are seen as one of the most perspective platforms in quantum computing.
