Lattice methods for strongly interacting many-body systems

Understand

Lattice field theory methods, usually associated with non-perturbative studies of quantum chromodynamics, are becoming increasingly common in the calculation of ground-state and thermal properties of strongly interacting non-relativistic few- and many-body systems, blurring the interfaces between condensed matter, atomic and low-energy nuclear physics.

• While some of these techniques have been in use in the area of condensed matter physics for a long time, others, such as hybrid Monte Carlo and improved effective actions, have only recently found their way across areas.
• With this topical review, we aim to provide a modest overview and a status update on a few notable recent developments.
• For the sake of brevity we focus on zero-temperature, non-relativistic problems.
