Multiple interfaces in diffusional phase transitions in binary mesogen-nonmesogen mixtures undergoing metastable phase separations
(American Physical Society, 2012-07)
Theory and simulations of simultaneous chemical demixing and phase ordering are performed for a mixed order parameter system with an isotropic-isotropic (I-I) phase separation that is metastable with respect to an ...
Phase-only optical encryption based on the zeroth-order phase-contrast technique
(SPIE-SOC PHOTOPTICAL INSTRUMENTATION ENGINEERS, 2009)
A phase-only encryption/decryption scheme with the readout based on the zeroth-order phase-contrast technique (ZOPCT), without the use of a phase-changing plate on the Fourier plane of an optical system based on the 4f ...
Defect-Induced Order-Order Phase Transition in Triblock Copolymer Thin Films
(American Chemical Society, 2021-02-08)
When a cylinder forming triblock copolymer thin film is exposed to supercritical carbon dioxide (scCO2), the system suffers an order-order phase transition from parallel (C∥) to perpendicularly oriented cylinders (C⊥). ...
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 ...
Ordered phases in the extended Hubbard model
(Elsevier B.V., 1994-04-02)
A novel method to probe the diverse phases for the extended Hubbard model (EHM), including the correlated hopping term, is presented. We extend an effective medium approach [1] to a bipartite lattice, allowing for charge- ...
Nakagami-m Phase-Envelope Joint Distribution: A New Model

Fourth order phase-field model for local max-ent approximants applied to crack propagation
(Elsevier Science Sa, 2016-12)
We apply a fourth order phase-field model for fracture based on local maximum entropy (LME) approximants. The higher order continuity of the meshfree LME approximants allows to directly solve the fourth order phase-field ...
