The authors describe a Monte Carlo algorithm for sampling the density of states directly by doing a random walk in energy space. The probability of a microstate is computed at any…

The van der Waals equation of state together with Maxwell’s equal area rule, leads to a transcendental equation for the densities of the two coexisting phases. Gibbs solved that this…
V. Bagnato and D. Kleppner, Phys. Rev. A, 44 (11), 7439-7441 (1991).
The authors demonstrate the possibility of Bose-Einstein condensation of an ideal Bose gas confined by one- and two-dimensional power-law traps. Problem 6.66 in Gould & Tobochnik is…
