摘要
We develop the dilute Bose gas model with random potential in order to understand the Bose system in random media such as He-4 in porous glass. Using the random potential taking account of the pore size dependence, we can compare quantitatively the calculated specific heat with the experimental results, without free parameters. The agreement is excellent at low temperatures, which justifies our model. Our model can predict some unobserved phenomena in this system. (C) 2003 Elsevier Science B.V. All rights reserved.
