Dynamics of transient metastable states in mixtures under coupled phase ordering and chemical demixing
(Iop Publishing, 2011-10-12)
We present theory and simulation of simultaneous chemical demixing and phase ordering in a polymer-liquid crystal mixture in conditions where isotropic-isotropic phase separation is metastable with respect to isotropic-nematic ...
Multicritical phase diagram of the three-dimensional Ashkin-Teller model including metastable and unstable phases
(Elsevier B.V., 2019-01-01)
The mean field approximation from the Bogoliubov inequality is applied to study the ferromagnetic Ashkin-Teller model in three dimensions. Phase transitions for the stable, metastable and unstable states is observed. From ...
Evidence of room temperature charge-density wave behavior and glass-like states in pressed pellets of lightly doped poly (3-methyl thiophene)
(Taylor & Francis Ltd, 2002-01-01)
We show room temperature charge-density wave (CDW) characteristics in d.c. and a.c. electric data in pressed pellets of lightly doped poly(3-methylthiophene). The possibility of a Peierls glass is discussed and metastables ...
Glassy states in the stochastic Potts model
(ELSEVIER SCIENCE BV, 2009)
We have studied by numerical simulations the relaxation of the stochastic seven-state Potts model after a quench from a high temperature down to a temperature below the first-order transition. For quench temperatures just ...
Dynamic functional connectivity and brain metastability during altered states of consciousness
(Academic Press Inc Elsevier Science, 2018-10)
The scientific study of human consciousness has greatly benefited from the development of non-invasive brain imaging methods. The quest to identify the neural correlates of consciousness combined psychophysical experimentation ...
Crystal structure of tetrabutylammonium nitroprusside dihydrate, [(C4H9)4N]2[Fe(CN)5NO]·2H2O, and vibrational spectra of ground and metastable excited states of the dihydrate and the anhydrate
(Springer/Plenum Publishers, 2001-10)
The crystal structure of tetrabutylammonium nitroprusside dihydrate (TBANPDH, [(C4H9)4N]2[Fe(CN)5NO]·2H2O) was determined by single crystal X-ray diffraction (XRD) and the compound was also studied, as well as the anhydrous ...
