Ideal Bose gas in fractal dimensions and superfluid He in porous media
نویسندگان
چکیده
Physical properties of ideal Bose gas with the fractal dimensionality between D = 2 and D = 3 are theoretically investigated. Calculation shows that the characteristic features of the specific heat and the superfluid density of ideal Bose gas in fractal dimensions are strikingly similar to those of superfluid Helium-4 in porous media. This result indicates that the geometrical factor is dominant over mutual interactions in determining physical properties of Helium-4 in porous media.

un 2 00 3 Condensate of charged Bose disks with numerous holes in a uniform magnetic field
A stack of disks with numerous holes composed of a non-interacting charged Bose gas is modeled as a low dimensional disk. The Bose condensation of the net-like disk system in a uniform magnetic field is studied. Calculation of the condensate fraction of the net-like disk system showed that there still exists a non-zero condensate fraction at low temperature and in weak field. PACS numbers: 05.3...
متن کاملDynamics of quantum liquids in confinement, theory and experiment.
Liquid (4)He immersed in porous media such as aerogel, Vycor, and Geltech silica are excellent examples of bosons in disorder and confinement. Of special interest is the impact of disorder on Bose-Einstein condensation (BEC), on the elementary excitations of the superfluid and on their connection to the superfluid properties. Indeed, the modifications induced by disorder can be used to reveal t...
متن کاملSpecial Section: the Legacy of Albert Einstein
Classically identical particles become quantum mechanically indistinguishable. Satyendra Nath Bose taught us, in 1924, how to correctly count the distinct microstates for the indistinguishables, and for a gas of light quanta (later photons), whose number is not conserved, e.g., can vary with temperature, he gave a proper derivation of Planck’s law of black body radiation. Einstein, in 1925, gen...
متن کاملGas-liquid Relative Permeability Estimation in 2D Porous Media by Lattice Boltzmann Method: Low Viscosity Ratio 2D LBM Relative Permeability
This work is a primary achievement in studying the CO2 and N2–oil systems. To predict gas-liquid relative permeability curves, a Shan-Chen type multicomponent multiphase lattice Boltzmann model for two-phase flow through 2D porous media is developed. Periodic and bounce back boundary conditions are applied to the model with the Guo scheme for the external body force (i.e.,...
متن کاملBoson localization and excitations of liquid He confined in gelsil
We present neutron scattering measurements of the phonon-roton (P-R) modes of liquid He confined in 44 Å mean pore diameter gelsil in the wave vector range 0.4 ≤ Q ≤ 2.15 Å. Layer modes, modes which propagate in the liquid layers adjacent to the porous media walls, were also observed at wave vectors in the roton region (Q ' 1.95 Å) but not at Q ∼ 1.7 Å. As the gelsil is filled with He, the P-R ...
