This is a Julian Schwinger Workshop on Multiscale Physics, made possible by a gift from the Julian Schwinger Foundation for Physics Research (JSF).

In a multitude of research problems at the forefront of hard- and soft-matter simulation, adequate sampling of the energy landscape is a major challenge. Overcoming the energy barriers in the search for equilibrium states and accurately characterizing temporal evolution that occurs as a system evolves through a series of minima limit progress in understanding materials synthesis and processing, biology, colloidal engineering, and earth sciences. Despite advances in computing hardware, brute-force application of conventional molecular dynamics and Monte Carlo methods is not sufficient in many cases. Specialized algorithms and methods have been developed to navigate the energy landscape. In this workshop, we will discuss advances and challenges in methods such as transition-path sampling and transition-interface sampling, alchemical methods, umbrella sampling, identifying order parameters and collective variables, accelerated molecular dynamics, metadynamics, variational approaches, replica methods, and coarse-graining. We will bring together experts in sampling methods across disciplines including physics, chemistry, materials science, engineering, and mathematics.

This workshop will include a poster session; a request for posters will be sent to registered participants in advance of the workshop.
