Cascade of the delocalization transition in a non-Hermitian interpolating Aubry-Andr{é}-Fibonacci chain
Liang-Jun Zhai, Guang-Yao Huang, Shuai Yin
In this paper, the interplay of the non-Herimiticity and the cascade of delocalization transition in the quasi-periodic chain is studied. The study is applied in a non-Hermitian in…
Large-Range Frequency Tuning of a Narrow-Linewidth Quantum Emitter
Liang Zhai, Matthias C. Löbl, Jan-Philipp Jahn +5
A hybrid system of a semiconductor quantum dot single photon source and a rubidium quantum memory represents a promising architecture for future photonic quantum repeaters. One of…
Many-body localization in a non-Hermitian quasi-periodic system
Liang-Jun Zhai, Shuai Yin, Guang-Yao Huang
In the present study, the interplay among interaction, topology, quasiperiodicity, and non-Hermiticity is studied. The hard-core bosons model on a one-dimensional lattice with asym…
Low-Noise GaAs Quantum Dots for Quantum Photonics
Liang Zhai, Matthias C. Löbl, Giang N. Nguyen +6
Quantum dots are both excellent single-photon sources and hosts for single spins. This combination enables the deterministic generation of Raman-photons -- bandwidth-matched to an…
A wave-function ansatz method for calculating field correlations and its application to the study of spectral filtering and quantum dynamics of multi-emitter systems
Sumanta Das, Liang Zhai, Mantas Čepulskovskis +4
We develop a formalism based on a time-dependent wave-function ansatz to study correlations of photons emitted from a collection of two-level quantum emitters. We show how to simul…
Radiative Auger Process in the Single-Photon Limit
Matthias C. Löbl, Clemens Spinnler, Alisa Javadi +8
In a multi-electron atom, an excited electron can decay by emitting a photon. Typically, the leftover electrons are in their ground state. In a radiative Auger process, the leftove…
