Ripplon spectrum of liquid ⁴He

Abstract

임과 매시의 모델을 사용한 리플론 스펙트럼이 변분적으로 전 파벡터들에 대하여 계산되어진다. 0.1565Å 보다 적은 작은 파벡터들에 대하여 0체기압에서 역시 유체동역학을 사용하여 구해진다. 계산된 결과는 에드왈즈, 에칼트와 가스파리니의 결과와 잘 일치한다.

Ripplon spectrum using the model of Yim and Massey is calculated for entire wave bectors, variationally, at zero bulk pressure. For small wave vectors less than 0.1565Å it is also obtained using a hydrodynamics. The present result is in good agreement with the result of Edwards. Eckardt and Gasparini.
