Explore multiscale quantum mechanics through this comprehensive workshop featuring leading researchers discussing integration of quantum methods across different spatial and temporal scales. Delve into cutting-edge approaches for coupling quantum theories from field theory to continuum levels, examining how to combine existing quantum methods at various accuracy and efficiency levels while reducing their limitations and expanding their applicability. Learn about electronic orbital applications from density-functional theory in many-body Green's function theories, explicitly correlated methods, quantum impurity models, quantum embedding theories, and quantum computation of electronic structure. Discover multiscale coupling techniques that unite approximate many-body Hamiltonians with Maxwell's equations for treating van der Waals and Casimir interactions from microscopic to macroscopic systems. Attend presentations covering polaritonic quantum materials, post-DFT Green's function embedding, quantum electrodynamic modeling, tensor networks in quantum chemistry, machine learning force fields, and dispersion modeling for million-atom systems. Gain insights into twisted transition metal dichalcogenides, 2D van der Waals heterostructures at moiré scale, superconducting quantum systems, and quantum matter through talks by experts from leading institutions addressing the fundamental challenge of approaching exact solutions to the Schrödinger equation while significantly accelerating many-body calculations.
