Interaction-induced topological properties of two bosons in flat-band systems
G. Pelegrí, A. M. Marques, V. Ahufinger +2
In flat-band systems, destructive interference leads to the localization of non-interacting particles and forbids their motion through the lattice. However, in the presence of inte…
Methods for the construction of interacting many-body Hamiltonians with compact localized states in geometrically frustrated clusters
F. D. R. Santos, R. G. Dias
Adding interactions to many-body Hamiltonians of geometrically frustrated lattices often leads to diminished subspaces of localized states. In this paper, we show how to construct…
One-dimensional topological insulators with noncentered inversion symmetry axis
A. M. Marques, R. G. Dias
In this paper, we discuss the characteristic features of one-dimensional topological insulators with inversion symmetry but noncentered inversion axis in the unit cell, for any cho…
Analytical solution of open crystalline linear 1D tight-binding models
A. M Marques, R. G. Dias
A method for finding the exact analytical solutions for the bulk and edge energy levels and corresponding eigenstates for all commensurate Aubry-André/Harper single-particle models…
