[npj Computational Materials, IF: 11.9]<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>Professor Dongbin Shin, in collaboration with the Max Planck Institute in Germany, has successfully provided a theoretical understanding of the complex phase transitions and superconducting phenomena in the organic molecular solid family \u03ba-(BEDT-TTF)<sub>2<\/sub>X. In particular, the team performed precise electronic structure calculations for \u03ba-(BEDT-TTF)<sub>2<\/sub>Cu<sub>2<\/sub>(CN)<sub>3<\/sub>, resolving longstanding discrepancies between experimental observations and conventional first-principles approaches. By employing a newly developed Hubbard U method to correct molecular orbital energy levels, they achieved quantitative agreement with experiments for the band gap, optical conductivity, and the pressure-driven metal\u2013insulator transition. Notably, the superconducting dome originating from the flat band at the Fermi level was successfully reproduced at the theoretical level. Furthermore, the researchers proposed a new low-energy lattice model that enables systematic studies of quantum spin liquid states and many-body interactions.
