Systematic cRPA study of two-dimensional MAZ materials: From unconventional screening to correlation-driven instabilities
F. Bagherpour, Y. Yekta, H. Hadipour +5
Understanding the interplay between screening, electronic correlations, and collective excitations is essential for the design of two-dimensional quantum materials. Here, we presen…

Strength of effective Coulomb interaction in two-dimensional transition-metal Halides MX and MX (M=Ti, V, Cr, Mn, Fe, Co, Ni; X=Cl, Br, I)
Y. Yekta, H. Hadipour, E. Sasioglu +4
We calculate the strength of the effective onsite Coulomb interaction (Hubbard ) in two-dimensional (2D) transition-metal (TM) dihalides MX and trihalides MX (M=Ti, V, C…
