金属氢超导临界温度的计算
Calculation of metallic hydrogen superconducting critical temperature
【摘要】 给出了强耦合超导体电 -声耦合常数λ=2∫dωωα2 (ω)F(ω)的计算公式 .数值计算表明 ,铅(Pb)的λ =1 .488,Tc =6 .5 0K ,而具有HCP结构的金属氢的的λ=1 .848,Tc =1 5 8.2K .
【Abstract】 In this paper, we gave a calculation formula of coupling superconductor electron-phonon coupling constant λ=2∫ d ωωα 2(ω)F(ω). Numerical value calculation showed that λ=1.488,T c=6.50? K,of the lead(Pb), and λ=1.848,T c=158.2? K of metallic hydrogen with HCP structure.
