Existence of long-range magnetic order in Heisenberg spin nanoribbons with edge modification
《Communications in Theoretical Physics》2024年第7期134-144,共11页Da-cheng Ma Ling-yi Cui Chu-xiao Sun Xiao-dan Chi Zheng-Nan XianYu An Du 
supported by the 111 Project(B16009).
Long-range magnetic order appears on a side decorated Heisenberg spin nanoribbon at nonzero temperature,although no spontaneous magnetization exists in a one-or two-dimensional isotropic Heisenberg model at any nonzer...

Topological and dynamical phase transitions in the Su–Schrieffer–Heeger model with quasiperiodic and long-range hoppings
《Communications in Theoretical Physics》2022年第7期146-153,共8页Wei-Jie Zhang Yi-Piao Wu Ling-Zhi Tang Guo-Qing Zhang 
supported by the National Natural Science Foundation of China(Grant No.12104166);the Key-Area Research and Development Program of Guangdong Province(Grant No.2019B030330001);the Science and Technology of Guangzhou(Grant No.2019050001);the Guangdong Basic and Applied Basic Research Foundation(Grant No.2020A1515110290)。
Disorders and long-range hoppings can induce exotic phenomena in condensed matter and artificial systems.We study the topological and dynamical properties of the quasiperiodic SuSchrier-Heeger model with long-range ho...

Tricritical and Critical Exponents in Microcanonical Ensemble of Systems with Long-Range Interactions
《Communications in Theoretical Physics》2016年第12期638-642,共5页Liang-Sheng Li 
Supported by the National Natural Science Foundation of China under Grant No.11104032
We explore the tricritical points and the critical lines of both Blume Emery Griffiths and Ising model within long-range interactions in the microcanonical ensemble.For K = Kmtp,the tricritical exponents take the val...

Quantum Correlation in Matrix Product States of One-Dimensional Spin Chains
《Communications in Theoretical Physics》2015年第9期356-360,共5页祝敬敏 
Supported by the National Natural Science Foundation of China under Grant No.10974137;the Major Natural Science Foundation of the Educational Department of Sichuan Province under Grant No.14ZA0167
For our proposed composite parity-conserved matrix product state(MPS), if only a spin block length is larger than 1, any two such spin blocks have correlation including classical correlation and quantum correlation. B...

Microscopic Superconductivity and Room Temperature Electronics of High-T_c Cuprates
《Communications in Theoretical Physics》2008年第11期1237-1240,共4页LIU Fu-Su CHEN Wan-Fang 
Abstract This paper points out that the Landau criterion for macroscopic superfluidity of He H is only a criterion for microscopic superfluidity of ^4He, extends the Landau criterion to microscopic superconductivity i...
