Metal-insulator transitions in pressed pellets of BF4 - doped poly(3-methylthiophene)
(1997-12-01)
From Electron Spin Resonance (ESR) data in pressed pellets of BF4 - doped Poly(3-methylthiophene) (P3MT) we obtained simultaneously the paramagnetic susceptibility and. the microwave conductivity. We observed a transition ...

Metal-insulator transition in Nd1-xEuxNiO 3 compounds
(2006-07-05)
Polycrystalline Nd1-xEuxNiO3 (0≤x≤0.5) compounds were synthesized in order to investigate the character of the metal-insulator (MI) phase transition in this series. Samples were prepared through the sol-gel route and ...
Modelling Diffusion Effects in Fertility Transition
(1993)
Mathematical models bind theory to precise formulations, and by doing so accentuate logical inconsistences in theories and facilitate their testing. In this article we explore the implications of simple mathematical models ...

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 ...
Dynamical phase transitions and Loschmidt echo in the infinite-range XY model
(Royal Soc, 2016)
We compare two different notions of dynamical phase transitions in closed quantum systems. The first is identified through the time-averaged value of the equilibrium-order parameter, whereas the second corresponds to ...
Stochastic transit equilibrium
(Elsevier, 2013)
We present a transit equilibrium model in which boarding decisions are stochastic. The
model incorporates congestion, reflected in higher waiting times at bus stops and increasing
in-vehicle travel time. The stochastic ...
A Bayesian Interpretation of First-Order Phase Transitions
(Springer, 2015)
In this work we review the formalism used in describing the thermodynamics
of first-order phase transitions from the point of view of maximum entropy
inference. We present the concepts of transition temperature, latent ...
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 ...
