Magnetic susceptibility of liquid 3He
He is a model of Fermi liquid, isotropic, its Fermi temperature is attainable and the interaction between atoms can be controlled by changing the pressure on the liquid. In this paper we present accurate cw-NMR measurements of the nuclear magnetic susceptibility of liquid He as a function of temperature and pressure. The emphasis has been placed in reliable thermometry, He pressure measurements...
متن کاملThermodynamic properties of polarized liquid 3He along different isentropic paths
The dependence of some thermodynamic properties of spin-polarized liquid 3He such as velocity of sound, adiabatic index, isentropic compressibility and temperature on the spin polarization has been investigated along different isentropic paths. The Lennard-Jones potential has been used in our calculations. It has been found that for higher values of entropy, the spin polarization has greate...
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....
متن کاملHigh-momentum response of liquid 3He.
A final-state-effects formalism suitable to analyze the high-momentum response of Fermi liquids is presented and used to study the dynamic structure function of liquid 3He. The theory, developed as a natural extension of the Gersch-Rodriguez formalism, incorporates the Fermi statistics explicitly through a new additive term which depends on the semidiagonal two-body density matrix. The use of a...
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...
