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…
Out-of-time-ordered correlator in non-Hermitian quantum systems
Liang-Jun Zhai, Shuai Yin
We study the behavior of the out-of-time-ordered correlator (OTOC) in a non-Hermitian quantum Ising system. We show that the OTOC can diagnose not only the ground state exceptional…
The internal energies of Heisenberg magnetic systems
Huai-Yu Wang, Liang-Jun Zhai, Meichun Qian
The internal energies, including transverse and longitudinal parts, of quantum Heisenberg systems for arbitrary spin S are investigated by the double-time Green's function method.…
Correlations between Optical Properties and Voronoi-Cell Area of Quantum Dots
Matthias C. Löbl, Liang Zhai, Jan-Philipp Jahn +7
A semiconductor quantum dot (QD) can generate highly indistinguishable single-photons at a high rate. For application in quantum communication and integration in hybrid systems, co…
