A Microscopic Look at Liquid Helium: the He Impurity Case
The description of the properties of liquid Helium is a challenge for any microscopic many–body theory. In this context, we study the ground state and the excitation spectrum of one He impurity in liquid He at T = 0 with the aim of illustrating the power of the correlated basis function formalism in describing heavily correlated systems. The strong interatomic interaction and the large density ...
متن کاملResponse of liquid 3He at finite temperatures.
The random-phase-approximation ~RPA! dynamical response of liquid He at finite temperatures has been calculated using an effective density-dependent atom-atom interaction. The interaction contains a zero-range part of Skyrme type, supplemented by a weighted density approximation to account for short-range correlations, and a long-range effective interaction of Lennard-Jones type. The calculated...
متن کاملVariational Calculations for the Relativistic Interacting Fermion System at Finite Temperature: Application to Liquid 3He
In this paper, at first we have formulated the lowest order constrained variational method for the relativistic case of an interacting fermion system at finite temperature. Then we have used this formalism to calculate some thermodynamic properties of liquid in the relativistic regime. The results show that the difference between total energies of relativistic and non-relativistic cases of liqu...
متن کاملCalculation of Thermodynamic Properties of the Quasi-one Dimensional Liquid 3He at Finite Temperature
We have used a variational approach to calculate some thermodynamic properties of the quasi-one dimensional liquid 3He such as the energy, entropy, free energy, equation of state and heat capacity at finite temperature. We have employed the Lennard-Jones potential as the inter-atomic interaction. We have seen that the total energy increases by increasing both temperature and density....
