Density-matrix-renormalization-group study of excitons in poly-diacetylene chains
Gergely Barcza, Örs Legeza, Florian Gebhard +1
We study the elementary excitations of a model Hamiltonian for the -electrons in poly-diacetylene chains. In these materials, the bare band gap is only half the size of the obse…

Quantum information analysis of the phase diagram of the half-filled extended Hubbard model
C. Mund, O. Legeza, R. M. Noack
We examine the phase diagram of the half-filled one-dimensional extended Hubbard model using quantum information entropies within the density-matrix renormalization group. It is we…
