In this talk I will cover two different scenarios in which the technique of bosonization, as well as the reversed process of de-bosonization, are applied to problems that involve transport calculations across junctions. The case of a junction between two Fermi liquids will be used to illustrate how the use of bosonization in the conventional ways can give rise to results which are not fully consistent with the exact direct solution of the problem. The differences are not only quantitative, but for certain aspects the two solutions are also qualitatively different.

Geometric frustration in Mott insulators permits perturbative electron fluctuations controlled by local spin configurations [1]. An equilateral triangle ("trimer") of spins with S=1/2 is the simplest example, in which low-energy degrees of freedom consist of built-in magnetic and electric dipoles arising from the frustrated exchange interaction. Such trimers can be weakly coupled to make multiferroics by design [2].

Mean field games theory is a recent research area, at the frontier between applied mathematics, social sciences, and physics. It was initiated a decade ago by Pierre-Louis Lions and Jean-Michel Lasry as a tool to model certain social phenomena involving a significant number of actors - through a game theory approach - while maintaining a reasonable level of simplicity thanks to the concept of mean-field imported from physics.
