We aim to bring together the top experts approaching the same outstanding physical problem in two greatly different ways. The main subject will be the strange metallic behavior, as viewed from the perspective of the holographic theories and the microscopic theories based on interacting lattice models. Particular focus will be given to the direct comparison between the two general approaches. The workshop will also cover the specific realizations of the ubiquitous strange metal regime: in the cuprates and other strongly correlated materials, moire systems and cold atom simulators. The goal of the workshop is to provide a wider perspective on the theoretical work focusing on the strange metals, a better overview of the established phenomenology, and a connection of the strange metal to other phenomena in strongly correlated electronic systems. The workshop will be public and can be joined via the following links: Day 1 (23/05/2022) Day 2 (24/05/2022) Day 3 (25/05/2022) The full program can be found here. ... Read More

In the last three months our computational cluster got fully upgraded. We have developed several new codes that are already put into production. Mihailo Čubrović has found a promising AdS model that appears to capture the single-particle propagator for the Hubbard model in a wide range of parameters. The mixed-basis method developed by Veljko Janković is know fully benchmarked and is already allowing access to lattice sizes that cannot be treated with the Lanczos method. Ivana Vasić has implemented the Gutzwiller method and is already producing results for the optical conductivity in the bosonic Hubbard model. Jakša Vučičević has completed the work on the Hubbard model in magnetic field using DMFT, which led to two new preprints on ... Read More

The two papers document in detail the DMFT solution for the conductivity in the square-lattice Hubbard model. In the regime of moderate incoherence of the electrons, the conductivity displays quantum oscillations which are fundamentally different from the conventional Shubnikov-de Haas (SdH) oscillations. This result presents a striking example of interplay between strong magnetic fields and electronic correlations, and is likely to motivate further experimental and theoretical ... Read More
