It is remarkable how the Fröhlich polaron, one of the simplest examples of a Quantum Field Theoretical problem, as it basically consists of a single fermion interacting with a scalar Bose field of ion displacements, has resisted full analytical or numerical solution at all coupling since ∼1950, when its Hamiltonian was first written. The field has been a testing ground for analytical, semi-analytical and numerical techniques, such as path integrals, strong-coupling perturbation expansion, advanced variational, exact diagonalization (ED) and quantum Monte Carlo (QMC) techniques. This paper reviews recent developments in the field of continuum and discrete (lattice) Fröhlich (bi)polarons starting with the basics and covering a number of active directions of research.

• Cold hybrid ion-atom systems (2017, background): “The induced change in the medium together with the moving particle forms a quasiparticle called a polaron, and can be characterised by its selfenergy, effective mass, and response to external (e.g., electric and magnetic) fields (Devreese and Alexandrov, 2009).”
