FUNDAMENTOS: An electronic quantum simulator (EQS)

The mechanism behind high-Tc superconductivity is one of the main open questions in physics. Recent progress in the field suggests that superconductivity in these materials emerges from the presence of antiferromagnetic spin fluctuations. However, a holistic understanding of high-temperature superconductors is hindered by the absence of experimental methods to probe the dynamics of the strongly correlated states. In this project, ICFO will join forces with researchers from the MIT (USA) and the University of Harvard (USA) to propose a novel electronic quantum simulator that is able to carry out quantum projection measurements of the many-body quantum wavefunction in high-Tc superconductivity. Inspired by the quantum gas microscope used for atomic optical lattices, we will develop a superlattice quantum simulator probed with a quantum projection microscope. The electronic quantum simulator will enable not only probing the many-body quantum wavefunction of correlated electronic states, but also measuring macroscopic observables, such as electrical resistivity and magnetization. This new quantum simulator platform may unravel the microscopic nature of high-Tc superconductivity and other correlated electron states, such as heavy fermions in a Kondo lattice, integer and fractional Chern insulators, and orbital ferromagnets.
