👉 In the context of theoretical physics, a "homologiser" is a system that can be considered to be composed of two or more identical particles. This allows for the possibility of an infinite number of configurations due to the symmetry properties of quantum mechanics. Homologers are often used in the study of quantum many-body systems, where the particles themselves form a homologous configuration. For instance, in a system with three identical fermions (like electrons), it is possible to have four different states
