Unparticles as recently suggested by H. Georgi are identities that are not constrained by dispersion relations but are governed by their scaling dimension, d. We show that their coupling to particles results in macroscopic interactions between matter. The interaction potentials are generally an inverse non-integral power of distance depending on d. This is totally different from known macroscop...

A continuum random phase approximation ~RPA! method for evaluating the structure function of nuclear matter is developed, where exchange terms for any particle-hole interaction are explicitly included. The method is applied to the inclusive transverse quasielastic electron scattering response at momentum transfer ranging from q5300 to 550 MeV/c . The interaction employed is a g8 Landau-Migdal c...

The effects of spin-orbit coupling on the two-electron spectra in lateral coupled quantum dots are investigated analytically and numerically. It is demonstrated that in the absence of magnetic field, the exchange interaction is practically unaffected by spin-orbit coupling, for any interdot coupling, boosting prospects for spin-based quantum computing. The anisotropic exchange appears at finite...

Low-energy electron diffraction (LEED) is considered as elastic electron-atom scattering (EEAS) operating in a target crystal waveguide, where signal carrier wave wavenumber modulated by exchange-correlation (XC) interaction. A potential designed using KKR (Korringa-Kohn-Rostoker) muffin-tin (MT) model built on overlapping MT spheres that implement atoms with double degree of freedom, radius an...

Using low-temperature scanning tunneling spectroscopy applied to the Cs-induced two-dimensional electron system (2DES) on p-type InSb(110), we probe electron-electron interaction effects in the quantum Hall regime. The 2DES is decoupled from bulk states and exhibits spreading resistance within the insulating quantum Hall phases. In quantitative agreement with calculations we find an exchange en...
