Photon-photon scattering in vacuum is extremely weak. However, strong effective
interactions between single photons can be realized by employing strong light-matter …

This article reviews theoretical and experimental developments for one-dimensional Fermi
gases. Specifically, the experimentally realized two-component delta-function interacting …

We show that two-photon transport is strongly correlated in one-dimensional waveguide
coupled to a two-level system. The exact S matrix is constructed using a generalized Bethe …

We consider the transport properties of multiple-particle quantum states in a class of one-
dimensional systems with a single quantum impurity. In these systems, the local interaction …

We provide a pedagogical review of the main ideas and results in non-equilibrium conformal
field theory and connected subjects. These concern the understanding of quantum transport …

We have developed a numerical approach to compute real-time path integral expressions
for quantum transport problems out of equilibrium. The scheme is based on a deterministic …

We provide a systematic treatment of N-photon transport in a waveguide coupled to a local
system using the input-output formalism. The main result of the paper is a general …

We propose a numerical renormalization group (NRG) approach to steady-state currents
through nanodevices. A discretization of the scattering-states continuum ensures the correct …

One of the main open problems in the field of transport in strongly interacting nanostructures
is the understanding of currents beyond the linear response regime. In this work, we …

We develop an iterative, numerically exact approach for the treatment of nonequilibrium
quantum transport and dissipation problems that avoids the real-time sign problem …
