Implications of exceptional points for few-photon transport in waveguide quantum electrodynamics
Shanshan Xu, Shanhui Fan
We identify a general connection between the physics of exceptional points in non-Hermitian systems and the few-photon bound states in waveguide quantum electrodynamics (QED) syste…
Few-photon scattering and emission from open quantum systems
Rahul Trivedi, Kevin Fischer, Shanshan Xu +2
We show how to use the input-output formalism compute the propagator for an open quantum system, i.e. quantum networks with a low dimensional quantum system coupled to one or more…
Generate tensor network state by sequential single-photon scattering in waveguide QED systems
Shanshan Xu, Shanhui Fan
We propose a scheme to generate photonic tensor network states by sequential scattering of photons in waveguide QED systems. We show that sequential scatterings can convert a serie…
Creating anyons from photons using a nonlinear resonator lattice subject to dynamic modulation
Luqi Yuan, Meng Xiao, Shanshan Xu +1
We study a one-dimensional photonic resonator lattice with Kerr nonlinearity under the dynamic modulation. With an appropriate choice of the modulation frequency and phase, we find…
General structure of two-photon S matrix in waveguide quantum electrodynamics systems containing a local quantum system with multiple ground states
Shanshan Xu, Shanhui Fan
We present the general structure of two-photon S matrix for a waveguide coupled to a local quantum system that supports multiple ground states. The presence of the multiple ground…
Fano Interference in Two-Photon Transport
Shanshan Xu, Shanhui Fan
We present a general input-output formalism for the few-photon transport in multiple waveguide channels coupled to a local cavity. Using this formalism, we study the effect of Fano…
Input-Output Formalism for Few-Photon Transport: A Systematic Treatment Beyond Two Photons
Shanshan Xu, Shanhui Fan
We provide a systematic treatment of -photon transport in a waveguide coupled to a local system, using the input-output formalism. The main result of the paper is a general conn…
Run-up amplification of transient long waves
Themistoklis Stefanakis, Shanshan Xu, Denys Dutykh +1
The extreme characteristics of long wave run-up are studied in this paper. First we give a brief overview of the existing theory which is mainly based on the hodograph transformati…
