Abstract

The HIMMS project, led by renowned condensed matter physicist Dr. Dragan Mihailović, marks his third ERC-funded project. This five-year research initiative, supported by nearly €2.5 million, is a collaboration between IJS and the Nanocenter. It focuses on uncovering new, previously unknown metastable configurations in quantum materials.

The primary objective of HIMMS is to explore the ordering of electrons and quantum matter on ultrafast timescales, which have so far remained inaccessible to modern scientific methods. The project will develop and employ experimental techniques capable of imaging the motion of individual electrons with exceptional spatial and temporal resolution. Using advanced time-resolved excitation techniques and scanning tunneling microscopy, HIMMS will investigate individual and collective quantum transitions, the formation of metastable structures, relaxation processes, and quantum decoherence. HIMMS aims to reveal the complex physics of metastable quantum states, such as topological transitions and quantum jamming phenomena in nonlinear and non-equilibrium conditions. The project’s findings will expand our understanding of fundamental processes in quantum systems across various timescales, with significant implications for both basic research and the advancement of quantum computing. Through this project, Dr. Mihailović and his team demonstrate Slovenia’s ability to keep pace with global scientific trends and contribute meaningfully to groundbreaking discoveries.

Prof. Dragan Mihailović
Dr. Dragan Mihailović is one of the world’s leading researchers in time-resolved spectroscopy of complex materials. His work on high-temperature superconductors, low-dimensional quantum materials, and molecular magnetism has set new benchmarks in understanding dynamic phenomena in quantum systems. At the Jožef Stefan Institute, he established the Department of Complex Matter and the Centre of Excellence in Nanoscience and Nanotechnology. Dr. Mihailović has authored over 500 scientific papers, which have received more than 11,000 citations. His groundbreaking discoveries include ultrafast switching in hidden quantum states, the development of novel methods for studying real-time dynamic transitions, and contributions to high-impact journals like Science and Nature. Among his numerous achievements, Dr. Mihailović has pioneered studies on phase transitions in superconductors, charge density waves, Jahn-Teller phase transitions, and fullerenes using laser spectroscopy . His team discovered a hidden topological quantum state in an electronic crystal and developed record-breaking ultrafast memory elements, which opened new avenues for quantum material research. Together with Viktor Kabanov, he developed a fundamental theory of high-temperature superconductivity, recognized as crucial by Nobel laureate K. A. Müller. His groundbreaking discoveries also include a femtosecond quantum simulator, the implementation of Grover's algorithm, and research on fullerene compounds, where he unveiled the mechanism of ferromagnetism. In the field of nanotechnology, he participated in the discovery of molybdenum nanowires and studied their properties. In Slovenia, he introduced new experimental approaches, such as fullerene physics, molecular electronics, and the physics of high-temperature superconductors. As the first Slovenian recipient of an ERC Advanced Grant for established researchers in 2013, Dr. Mihailović delved into the study of ultrafast phase transitions and the creation of new exotic quantum states in matter. In 2017, through the ERC Proof of Concept grant, he developed an energy-efficient and ultrafast memory element based on TaS₂. His work in this field paves the way for new technological applications of quantum materials. In 2024, he once again secured ERC funding for the HIMMS project for established researchers.
