摘要翻译:
我用Landau理论证明了淬灭位错可以促进超晶(SS)到正常固态(NS)的转变,使得即使在无位错晶体中没有发生转变也有可能发生。详细预测了SS与NS转变温度T_c(L)、超流密度%\RhO_s(T,L)、比热C(T,L)与温度T和位错间距L的关系,所有这些都可以通过实验来验证。这些结果也应该适用于许多其他系统,例如铁磁体。

英文摘要:
I show using Landau theory that quenched dislocations can facilitate the supersolid (SS) to normal solid (NS) transition, making it possible for the transition to occur even if it does not in a dislocation-free crystal. I make detailed predictions for the dependence of the SS to NS transition temperature T_c(L), superfluid density %\rho_S(T, L), and specific heat C(T,L) on temperature T and dislocation spacing L, all of which can be tested against experiments. The results should also be applicable to an enormous variety of other systems, including, e.g., ferromagnets.
