Insulator-to-metal transition driven by clustering of solitons in polyacetylene
(1997-03-15)
It's believed that the simple Su-Schrieffer-Heeger Hamiltonian can not predict the insulator to metal transition of transpolyacetylene (t-PA). The soliton lattice configuration at a doping level y=6% still has a semiconductor ...

Cooperative elastic fluctuations provide tuning of the metal-insulator transition
(2019)
Metal-to-insulator transitions driven by strong electronic correlations occur frequently in condensed matter systems, and are associated with remarkable collective phenomena in solids, including superconductivity and ...
INSULATOR-TO-METAL TRANSITION IN POLYTHIOPHENE
(American Physical Soc, 1994-01-01)
In the present work, the electronic structure of polythiophene at several doping levels is investigated by the use of the Huckel Hamiltonian with sigma-bond compressibility. Excess charges are assumed to be stored in ...

First-order insulator-to-metal Mott transition in the paramagnetic 3D system GaTa4Se8
(American Physical Society, 2014-08-22)
The nature of the Mott transition in the absence of any symmetry breaking remains a matter of debate. We study the correlation-driven insulator-to-metal transition in the prototypical 3D Mott system GaTa4Se8, as a function ...

Soliton clusters inducing insulator-to-metal transition in polyacetylene: a Su-Schrieffer-Heeger model study
(Elsevier B.V., 2001-09-04)
The Su-Schrieffer-Heeger (SSH) Hamiltonian has been one of most used models to study the electronic structure of polyacetylene (PA) chains. It has been reported in the literature that in the SSH framework a disordered ...
