Real eigenvalues determined by recursion of eigenstates
《Chinese Physics B》2024年第3期196-200,共5页刘通 王友国 
This work was supported by the National Natural Science Foundation of China(Grant No.62071248);the Natural Science Foundation of Nanjing University of Posts and Telecommunications(Grant No.NY223109);China Postdoctoral Science Foundation(Grant No.2022M721693).
Quantum physics is primarily concerned with real eigenvalues,stemming from the unitarity of time evolutions.With the introduction of PT symmetry,a widely accepted consensus is that,even if the Hamiltonian of the syste...

Eigenstates and temporal dynamics in cavity optomagnonics
《Chinese Physics B》2023年第10期660-665,共6页丁云静 肖杨 
Project supported by the National Natural Science Foundation of China(Grant Nos.NSFC61974067 and 62374087)。
Many studies of magnon–photon coupling are performed in the frequency domain for microwave photons.In this work,we present analytical results of eigenfrequency,eigenstates,and temporal dynamics for the coupling betwe...

Analytical treatment of Anderson localization in a chain of trapped ions experiencing laser Bessel beams
《Chinese Physics B》2019年第1期240-244,共5页Jun Wen Jian-Qi Zhang Lei-Lei Yan Mang Feng 
Project supported by the National Natural Science Foundation of China(Grant Nos.11734018,11674360,11404377,and 91636220)
Trapped ions, under electromagnetic confinement and Coulomb repulsion, can behave as non-interacting particles in one-dimensional lattices. Here we explore analytically the possible effects regarding Anderson localiza...

Slater determinant and exact eigenstates of the two-dimensional Fermi–Hubbard model
《Chinese Physics B》2018年第7期264-267,共4页Jun-Hang Ren Ming-Yong Ye Xiu-Min Lin 
Project supported by the National Natural Science Foundation of China(Grant No.11674059);Natural Science Foundation of Fujian Province,China(Grant Nos.2016J01008 and 2016J01009)
We consider the construction of exact eigenstates of the two-dimensional Fermi-Hubbard model defined on an L ×L lattice with a periodic condition. Based on the characteristics of Slater determinants, several methods ...

Identifying the closeness of eigenstates in quantum many-body systems
《Chinese Physics B》2017年第8期66-73,共8页李海彬 杨扬 王沛 王晓光 
supported by the Natural Science Foundation of Zhejiang Province,China(Grant No.LY16A050004);the Fundamental Research Funds for the Central Universities,China(Grant No.2017FZA3005);the National Natural Science Foundation of China(Grant No.11475146)
We propose a quantity called modulus fidelity to measure the closeness of two quantum pure states. We use it to investigate the closeness of eigenstates in one-dimensional hard-core bosons. When the system is integrab...
