RKKY range function of a one-dimensional noninteracting electron gas
The apparently straightforward evaluation of the Ruderman-Kittel-Kasuya-Yosida RKKY range function, or more generally, of the linear density modulation n x induced at zero temperature in a noninteracting onedimensional electron gas by a localized static impurity modeled with a function potential has proven surprisingly troublesome. Although the original calculation gave an incorrect answer,1 mo...
متن کاملResonant Feshbach scattering of fermions in one-dimensional optical lattices
We consider Feshbach scattering of fermions in a one-dimensional optical lattice. By formulating the scattering theory in the crystal momentum basis, one can exploit the lattice symmetry and factorize the scattering problem in terms of center-of-mass and relative momentum in the reduced Brillouin zone scheme. Within a single band approximation, we can tune the position of a Feshbach resonance w...
متن کاملCalculation of Quasi-one-dimensional Interacting Electron Gas Using the Hartree-Fock Method
In this paper, the Hartree-Fock method has been formulated to investigate some of the ground state properties of quasi-one-dimensional interacting electron gas in the presence of the magnetic field. The bare coulomb interaction between electrons has been assumed. For this system, we have also computed some of its thermodynamic and magnetic properties such as the energy, pressure, incompressibil...
متن کاملThermalization in a quasi-one-dimensional ultracold bosonic gas
We study the collisional processes that can lead to thermalization in one-dimensional (1D) systems. For two-body collisions, excitations of transverse modes are the prerequisite for energy exchange and thermalization. At very low temperatures, excitations of transverse modes are exponentially suppressed, thermalization by two-body collisions stops and the system should become integrable. In qua...
متن کاملNaturally Light Fermions from Dimensional Reduction
We consider the 3-d Gross-Neveu model in the broken phase and construct a stable brane world by means of a domain wall and an anti-wall. Fermions of opposite chirality are localized on the walls and coupled through the 3-d bulk. At large wall separation β the 2-d correlation length diverges exponentially, hence a 2-d observer cannot distinguish this situation from a 2-d space-time. The 3-d 4-fe...
