[institut] [phys4phys] SCL Seminar: Jakša Vučičević, Thursday 18 September, 14:00

[Nenad Vukmirović]

Dear colleagues,

You are cordially invited to the SCL seminar of the Center for the Study 
of Complex Systems, which will be held on Thursday, 18 September 2025 at 
14:00 in the "Zvonko Marić" lecture hall of the Institute of Physics 
Belgrade. The talk entitled

Models and methods in the study of high-temperature superconductivity

will be given by Dr Jakša Vučičević (SCL, Institute of Physics 
Belgrade). The abstract of the talk:

We will cover several lines of ongoing work aimed at improving our 
understanding of the cuprate superconductors. We focus on the mechanisms 
that determine the normal-phase transport properties and the magnitude 
of the superconducting critical temperature. The main difficulty in the 
theoretical description of the cuprates is that it requires a many-body 
treatment of an effectively strong interaction between the electrons; in 
addition, the details of the crystal structure also play a role, and one 
cannot account for material-specific properties by solving the simplest 
models. We will discuss the possible low-energy models and the ways to 
extract the corresponding model-parameters from ab initio results [1,2]. 
Then, we will discuss recent advancements in methodology, in particular 
related to computing the dynamical response functions in interacting 
lattice models. Our results are pertinent to the hypothesis that the 
cuprate strange-metal regime is linked with quantum criticality [3,4].
