Spectral density of interacting pairs in low-dimensional finite lattices
T. Chattaraj
The spectral density of bound pairs in ideal 1D, 2D and Bethe lattices is computed for weak and strong interactions. The computations are performed with Green's functions by an eff…
Numerical Studies on Correlations in Dynamics and Localization of Two Interacting Particles in Lattices
Tirthaprasad Chattaraj
Correlation of interacting particles is studied in their dynamics and localization in ideal and disordered lattice systems with the help of numerical tools. Both 1D and 2D systems…
Spectral weights of doublon in interacting Hofstadter model
Tirthaprasad Chattaraj
In this article, two-particle Greens functions are computed for different strengths of interactions for particles in Hofstadter lattices, providing informations on spectral weights…
Localization parameters for two interacting particles in disordered two-dimensional lattices
Tirthaprasad Chattaraj
In two dimensional disordered lattices, presence of interaction makes particles less localized than the non-interacting ones within the range of disorder strength and int…
Pair functions computed recursively in ordered and disordered lattices
Tirthaprasad Chattaraj
In this article I study pairing of two interacting particles in ideal 1D, 2D and Bethe lattices. I employ the method of recursion that has been formulated recently by Berciu et. al…
Effects of long-range hopping and interactions on quantum walk in ordered and disordered lattices
T. Chattaraj, R. V. Krems
We study the effects of long-range hopping and long-range inter-particle interactions on quantum walk of hard-core bosons in ideal and disordered one-dimensional lattices. We find…
