Charge-density-wave formation in the Edwards fermion-boson model at one-third band filling
Satoshi Ejima, Holger Fehske
We examine the ground-state properties of the one-dimensional Edwards spinless fermion transport model by means of large-scale density-matrix renormalization-group calculations. De…

Order, criticality and excitations in the extended Falicov-Kimball model
S. Ejima, T. Kaneko, Y. Ohta +1
Using exact numerical techniques we investigate the nature of excitonic (electron-hole) bound states and the development of exciton coherence in the one-dimensional half-filled ext…

Exact-diagonalization study of exciton condensation in electron bilayers
T. Kaneko, S. Ejima, H. Fehske +1
We report on small-cluster exact-diagonalization calculations which prove the formation of electron-hole pairs (excitons) as prerequisite for spontaneous interlayer phase coherence…
