Path-integral calculation of the third virial coefficient of quantum gases at low temperatures.
We derive path-integral expressions for the second and third virial coefficients of monatomic quantum gases. Unlike previous work that considered only Boltzmann statistics, we include exchange effects (Bose-Einstein or Fermi-Dirac statistics). We use state-of-the-art pair and three-body potentials to calculate the third virial coefficient of (3)He and (4)He in the temperature range 2.6-24.5561 ...
متن کاملEffective Potential for the Second Virial Coefficient at Feshbach Resonance
In a recent paper entitled “High temperature expansion applied to fermions near Feshbach resonance”, (Phys. Rev. Lett. 92 160404 (2004)), Ho and Mueller have demonstrated a remarkable similarity between its high and low temerature properties at resonance. The quantum second virial coefficient plays a crucial role in their analysis, and has a universal value at resonance. In this paper, we explo...
متن کاملHaldane exclusion statistics and second virial coefficient.
We show that Haldanes new definition of statistics, when generalised to infinite dimensional Hilbert spaces, is equal to the high temperature limit of the second virial coefficient. We thus show that this exclusion statistics parameter, g , of anyons is non-trivial and is completely determined by its exchange statistics parameter α. We also compute g for quasiparticles in the Luttinger model an...
متن کاملSome comments on the second virial coefficient of semiflexible polymers.
A Monte Carlo study is made of the mean-square radius of gyration S(2) and second virial coefficient A(2) for the two freely rotating chains with the Lennard-Jones (LJ) 6-12 potential and the hard-sphere (HS) one in the range of the bond angle theta from 109 degrees (typical flexible chain) to 175 degrees (typical semiflexible or stiff chain) and in the range of the number n of bonds from 6 to ...
متن کاملV.C The Second Virial Coefficient & van der Waals Equation
• Remarks and observations: (1) The tail of the van der Waals attractive potential (∝ r) extends to very long sep arations. Yet, its integral in eq.(V.39) is dominated by contributions from the short scales r0. In this limited context, the van der Waals potential is short-ranged, and results in corrections to the ideal gas behavior that are analytical in density n, leading to the virial series...
