Overview

In condensed matter theory, a variety of collective phenomena emerging in real materials are explained in terms of appropriate effective models in the first stage of investigations and then in the second stage from the ab initio Hamiltonian. Given the rapid progress in the both stages and a rich variety of novel quantum phenomena found in recent years, bridging between the two stages is important more than ever. The main issues of this workshop/symposium are those related to (i) topological phases and (ii) physics in strongly-correlated systems including high-temperature superconductivity, with a goal of making a reliable first-principles prediction for the occurrence of nontrivial collective phenomena. For this purpose, we offer a place of intimate interactions among great theorists in diverse fields such as mathematical physics, many-body theory, field theory, and density functional theory for generating new problems, solutions, and/or collaborations in the future.

​

Anticipated topics to be discussed include:

1. Classification of topological phases in interacting systems

2. Elementary excitations in nontrivial quantum systems, including strongly-correlated, strong electron-phonon coupled, and topological phases: validity of the quasiparticle and/or polaron picture

3. Methods in the Green’s-function approach and the density functional theory for first-principles calculation of the superconducting Tc in strongly-correlated and/or strong electron-phonon coupled systems

4. Quantum entanglement as a tool to characterize quantum phases, and application to first-principles calculation
