چکیده
The dynamic form factor S(Q, co) in liquid He and He is evaluated in the wave-vector transfer o ] range 3&Q &15 A . The input is the pair interatomic potential, developed by Aziz et al. The S(Q, to) is calculated within the random-phase approximation (RPA) which becomes valid when RQ is much larger than the average momentum in the liquid. A T-matrix approximation represents the interaction appearing in the RPA. The aim is to explore how well S(Q, co) can be

Dynamics of entangled quantum optical system in independent media
We study the dynamics of two three-level atoms interacting with independent bosonic Lorentzian reservoirs at zero temperature. Such systems can be created in far astronomical objects. Quantum mechanical behaviour of these particles can produce detectable effects on the spectroscopic identifications of these objects, if such behaviour remain stable during the interaction with their media. It is ...
متن کاملSolidity of viscous liquids. III. relaxation
It is suggested that the −1/2 high-frequency decay of the loss in highly viscous liquids, which appears to be generic, is a manifestation of a negative long-time tail as typically encountered in stochastic dynamics. The proposed mechanism requires that the coherent diffusion constant is much larger than estimated from the relaxation time. This is justified by reference to the solidity of viscou...
متن کاملSpectroscopic signatures of crystal momentum fractionalization
We consider gapped Z2 spin liquids, where spinon quasiparticles may carry fractional quantum numbers of space group symmetry. In particular, spinons can carry fractional crystal momentum. We show that such quantum number fractionalization has dramatic, spectroscopically accessible consequences, namely enhanced periodicity of the two-spinon density of states in the Brillouin zone, which can be d...
متن کاملArtificial electric field in fermi liquids.
Based on the Keldysh formalism, we derive an effective Boltzmann equation for a quasiparticle constrained within a particular Fermi surface in an interacting Fermi liquid. This provides a many-body derivation of Berry curvatures in electron dynamics with spin-orbit coupling, which has received much attention in recent years in noninteracting models. As is well known, the Berry curvature in mome...
متن کاملNON-EQUILIBRIUM QCD: Interplay of hard and soft dynamics in high-energy multi-gluon beams
A quantum-kinetic formulation of the dynamical evolution of a high-energy non-equilibrium gluon system at finite density is developed, to study the interplay between quantum fluctuations of high-momentum (hard) gluons and the low-momentum (soft) mean color-field that is induced by the collective motion of the hard particles. From the exact field-equations of motion of QCD, a self-consistent set...
