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 ...

A thermodynamic model for the simultaneous charge/spin order transition in LaCu3Fe4O12
(IOP Publishing, 2012-11)
LaCu3Fe4O12 undergoes a phase transition at 393 K from an antiferromagnetic insulating state at low temperatures to a paramagnetic metallic state above the critical temperature. We build a basic model for the electronic ...
Will small energy consumers be faster in transition? Evidence from the early shift from coal to oil in Latin America
(2012)
This paper provide evidence of the early transition from coal to oil for 20 Latin American countries over the first half of the 20th century, which does not fit the transition experiences of large energy consumers. These ...
Local sustainable diets as a driver of the transition to agroecological food systems
(Ohann Heinrich Von Thunen Inst-Vti, 2020)
In this paper, we propose the promotion of local sustainable diets as a process that can facilitate the transition of current industrialised food systems to agroecological food systems. First, we describe the problem, which ...
Environmental factors related to biogeographical transition zones of areas of endemism of Neotropical mammals
(Csiro Publishing, 2018-01-31)
Biogeographical transition zones are areas of a complex biotic mixture located at the borders between biogeographical units. Climatic, physical and ecological factors should play an important role in allowing coexistence ...
Transit line structures in a general parametric city: The role of heuristics
(INFORMS Inst.for Operations Res.and the Management Sciences, 2018)
The merits of selected heuristics to obtain transit line structures are analyzed, applying them on a synthetic parametric description of a symmetric city that allows representation of different city types (mostly monocentric, ...
Coexistence of conducting and nonconducting phases on the metallic side of the mott transition in photoinjected semiconductors
(Journal of Physics and Chemistry of Solids, 1992)
The nonequilibrium steady state of a direct gap semiconductor is studied under high levels of photoexcitation by continuous laser light. The stability of the uniform steady state of itinerant carriers is probed resorting ...
Demographic transition in Argentina
(2014)
Demographic transition, epidemiological transition, changes in population. And these changes in the living conditions of the
population of Argentina in the last hundred years allow us to estimate that a girl born this ...
