Correlated metallic two particle bound states in quasiperiodic chains
Sergej Flach, Mikhail Ivanchenko, Ramaz Khomeriki
Single particle states in a chain with quasiperiodic potential show a metal-insulator transition upon the change of the potential strength. We consider two particles with local int…
Resonant invisibility with finite range interacting fermions
Jean-Pierre Nguenang, Sergej Flach, Ramaz Khomeriki
We study the eigenstates of two opposite spin fermions on a one-dimensional lattice with finite range interaction. The eigenstates are projected onto the set of Fock eigenstates of…
Realization of Discrete Quantum Billiard in 2D Optical Lattices
Dmitry O. Krimer, Ramaz Khomeriki
We propose the method for optical visualization of Bose-Hubbard model with two interacting bosons in the form of two-dimensional (2D) optical lattices consisting of optical wavegui…
Two interacting particles in a random potential
Dmitry O. Krimer, Ramaz Khomeriki, Sergej Flach
We study the scaling of the localization length of two interacting particles in a one-dimensional random lattice with the single particle localization length. We obtain several reg…
