DOI: 10.1088/1367-2630/aa9558
Abstract: Bosonization provides a powerful analytical framework to deal with one-dimensional strongly interacting fermion systems, which makes it a cornerstone in quantum many-body theory. Yet, this success comes at the expense of using effective infrared parameters,… read more here.

Abstract: Novel controlled non-perturbative techniques are a must in the study of strongly correlated systems, especially near quantum criticality. One of these techniques, bosonization, has been extensively used to understand one-dimensional, as well as higher dimensional… read more here.

DOI: 10.1142/s0217732323500153
Abstract: We discuss bosonization of non-Hermitian [Formula: see text] invariant fermion models in [Formula: see text] spacetime dimensions within the path-integral approach in which the generating functionals associated to the fermion and boson models can be… read more here.
