A schema for duality, illustrated by bosonization
In this paper we present a schema for describing dualities between physical
theories (Sections 2 and 3), and illustrate it in detail with the example of
bosonization: a boson-fermion duality in two-dimensional quantum field theory
(Sections 4 and 5).
The schema develops proposals in De Haro (2016, 2016a): these proposals
include construals of notions related to duality, like representation, model,
symmetry and interpretation. The aim of the schema is to give a more precise
criterion for duality than has so far been considered.
The bosonization example, or boson-fermion duality, has the feature of being
simple yet rich enough to illustrate the most relevant aspects of our schema,
which also apply to more sophisticated dualities. The richness of the example
consists, mainly, in its concern with two non-trivial quantum field theories:
including massive Thirring-sine-Gordon duality, and non-abelian bosonization.
This prompts two comparisons with the recent literature on dualities:---
(a) Unlike the standard cases of duality in quantum field theory and string
theory, where only specific simplifying limits of the theories are explicitly
known, the boson-fermion duality is known to hold exactly. This exactness can
be exhibited explicitly.
(b) The bosonization example illustrates both the cases of isomorphic and
non-isomorphic models: which we believe the literature on dualities has not so
far discussed
