Nonreciprocal Floquet tunneling dynamics of spin-orbit-coupled bosonic atoms in a non-Hermitian double-well potential
Limei Ju, Yingying Zhang, Jilei Liang +5
The stable tunneling dynamics in non-Hermitian quantum systems is one of the fundamental issues in the study of quantum transport. Nonreciprocal coupling, as another crucial manife…
Simultaneous estimation of relative phase and coherence in astronomical interferometry
Yawen Tang, Wei Ye, Lu Qin +6
Astronomical interferometry is a cornerstone technique for high-resolution stellar imaging and observational astrophysics, extracting spatial information from the coherence of ligh…
Stable (2+1)-dimensional soliton and breather molecules in a cold Rydberg atomic gas
Lu Qin, Hairu Zhai, Lu Liu +6
We investigate the formation of stable (2+1)-dimensional spatial-domain optical soliton molecules and breather molecules in a gas of Rydberg atoms, highlighting the role of the non…
Bright solitons in a spin-orbit-coupled dipolar Bose-Einstein condensate trapped within a double-lattice
Qi Wang, Jieli Qin, Junjie Zhao +8
By effectively controlling the dipole-dipole interaction, we investigate the characteristics of the ground state of bright solitons in a spin-orbit coupled dipolar Bose-Einstein co…
Itinerant ferromagnetism entrenched by the anisotropy of spin-orbit coupling in a dipolar Fermi gas
Xue-Jing Feng, Jin-Xin Li, Lu Qin +7
We investigate the the itinerant ferromagnetism in a dipolar Fermi atomic system with the anisotropic spin-orbit coupling (SOC),which is traditionally explored with isotropic conta…
Optimal optical Ferris wheel solitons in a nonlocal Rydberg medium
Jia-Bin Qiu, Lu Qin, Xing-Dong Zhao +1
We propose a scheme for the creation of stable optical Ferris wheel(OFW) solitons in a nonlocal Rydberg electromagnetically induced transparency(EIT) medium. Depending on a careful…
Symmetry-protected higher-order exceptional points in staggered flatband rhombic lattices
Yingying Zhang, Shiqiang Xia, Xingdong Zhao +9
Higher-order exceptional points (EPs), which appear as multifold degeneracies in the spectra of non-Hermitian systems, are garnering extensive attention in various multidisciplinar…
