- Title of Paper:Research and derivation for Wien’ displacement law by using catastrophe theory
- Journal:Modern Physics Letters B
- Summary:In this paper, Wien’s displacement law as one of the most important laws of thermal
radiation, for which Wien has won the Nobel Prize in Physics, is studied and derived from
the perspective of phase transition by using catastrophe theory. This paper describes
in detail how the control variable causes the phase transition of the system potential
function and the main indexes for judging whether the phase transition occurs. By
extending the control variable in the catastrophe theory affecting the thermal radiation
into multi-parameters form, the function equilibrium curve of the blackbody radiation is
solved, and then the two expressions of Wien’s displacement law including wavelengthtemperature and wavelength-temperature are derived theoretically. Furthermore, a phase
transition method is proposed to study the thermal radiation of blackbody. This not only
provides a new perspective for the research of thermal radiation, but also provides a new
idea for the study of other phase transitions. - Co-author:Zhuo Zhou, Jiu Hui Wu, Xiao Liang, Xiaoyang Yuan and Yun Lei Wang
