Generation of vortex-squeezed light in a coherently prepared medium
Fan Meng, Hao Zhu, Xin-Yao Huang +1
In this Letter, we theoretically propose an alternative scheme for generating vortex optical squeezing, based on the Raman scattering process in a coherently prepared medium, disti…
Advances in non-Hermitian dynamics of quadratic bosonic systems
Huawei Zhao, Xinlei Liu, Xinyao Huang +1
Non-Hermitian physics has emerged as a rapidly advancing field of research, revealing a range of novel phenomena and potential applications. Traditional non-Hermitian Hamiltonians…
Enhanced Charging in Multi-Battery Systems by Nonreciprocity
Hua-Wei Zhao, Yong Xie, Xinyao Huang +1
Quantum batteries (QBs), harnessing quantum systems to transfer and store energy, have garnered substantial attention recently, enabling potentials in enhanced charging capacity, i…
Multitype entanglement dynamics induced by exceptional points
Zigeng Li, Xinyao Huang, Hongyan Zhu +3
As a most important feature of non-Hermitian systems, exceptional points (EPs) lead to a variety of unconventional phenomena and applications. Here, we study a generic model compos…
Non-Hermitian skin effect and nonreciprocity induced by dissipative couplings
Xinyao Huang, Yaohua Li, Guo-Feng Zhang +1
We study the mechanism for realizing non-Hermitian skin effect (NHSE) via dissipative couplings, in which the left-right couplings have equal strengths but the phases do not satisf…
