THERMO-quantum field AND SUPERTHERMO STATE
收藏 引用
Science in China,Ser.A 1988年 第9期31卷 1104-1115页
作者: 桂元星 Department of Physics Dalian University of Technology
On the basis of the thermo-field dynamics and the quantum field theory in curved space, a new theory of 'thermo-quantum field' (TQF) is formulated. The TQF derives the equilibrium statistical mechanics from the quantu... 详细信息

Chinese Physics Letters 2008年 第8期25卷 2791-2794页
作者: 方恒忠 朱建阳 Department of Physics China University of Petroleum Dongying 257061 Department of Physics Beijing Normal University Beijing 100875
We calculate the Casimir effect at finite temperature in Minkowski spacetime by using statistical method, the approximate expressions of the Casimir effect in the low and high temperature limits are also discussed. Th... 详细信息

A path integral approach to electronic friction of a nanometer-sized tip scanning a metal surface
收藏 引用
Communications in Theoretical Physics 2021年 第4期73卷 111-120页
作者: Yang Wang Yu Jia School of Physics Zhengzhou UniversityZhengzhou 450001China International Laboratory for quantum Functional Materials of Henan and School of Physics and MicroelectronicsZhengzhou UniversityZhengzhou 450001China Key Laboratory for Special Functional Materials of Ministry of Education and School of Materials and EngineeringHenan UniversityKaifeng475001China
In this work,we study the dissipation mechanism and frictional force of a nanometer-sized tip scanning a metal surface via a path integral *** metal,with internal degrees of freedom(c,c^(†))and a tip with an internal ... 详细信息
