Thermodynamics of quantum fluids confined in zeolites at low temperature
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...

| Sumario: | 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-(formula presented) heat capacity and explores the crossover from 1D to higher dimensionality in terms of both temperature and cross-sectional dimension. © 2002 The American Physical Society. |
