Researchers from the Department of Complex Matter at the Jožef Stefan Institute, led by Prof. Dr. Dragan D. Mihailović, have published an article in the prestigious scientific journal Nature Communications titled A time-domain phase diagram of metastable states in a charge-ordered quantum material. In this study, Jan Ravnik, Michele Diego, Yaroslav Gerasimenko, Yevhenii Vaskivskyi, Igor Vaskivskyi, Tomaž Mertelj, and Jaka Vodeb present a time-evolving phase diagram of the quasi-two-dimensional material 1T-TaS₂. This material has recently attracted significant attention due to its multiple metastable electronically ordered quantum states, which can be induced by optical or electrical excitation. These properties make 1T-TaS₂ a promising candidate for the development of ultrafast memory devices. In their study, the authors performed the first systematic analysis of metastable states, determined the conditions for their formation, and examined the time evolution of phase boundaries as well as the influence of excitation parameters on the long-term stability of these states. Their findings are crucial for the further development of technologies based on controlled quantum transitions.
