Abstract
The thermal properties of quantum fluids at low temperature (T) are determined by the spectrum of excitations which possess the lowest frequencies. In the case of a fluid such as helium or hydrogen, confined in a one-dimensional (1D) pore, these excitations are phonons, with wave vector parallel to the pore's axis. This paper describes the consequences of this fluid's confinement for the low-T heat capacity and explores the crossover from 1D to higher dimensionality in terms of both temperature and cross-sectional dimension.
