We study a one-dimensional extended Peierls-Hubbard model coupled to intracell and intercell phonons for a half-filled band. The calculations are made using the Hartree-Fock and adiabatic approximations for arbitrary temperature. In addition to static spin, charge, and bond density waves, we predict intermediate phases that lack inversion symmetry, and phase transitions that reduce symmetry on ...

Emulsions comprising a dual-surfactant system of a long-chain amidoamine derivative and a quaternary ammonium salt developed an iridescent color at a specific temperature region. The emulsions underwent phase inversion on heating from an O/W emulsion to a W/O emulsion, passing through a periodical lamellar structure which developed a characteristic interference color. Interestingly, the color a...

S U M M A R Y We develop and study an adjoint-based inversion method for the simultaneous recovery of initial temperature conditions and viscosity parameters in time-dependent mantle convection from the current mantle temperature and historic plate motion. Based on a realistic rheological model with temperature-dependent and strain-rate-dependent viscosity, we formulate the inversion as a PDE-c...

spherical granules of the superionic conductor β/β́ lizr2(po4)3 in the range of sub 100 nm sizewere synthesizedvia freeze drying methodand fully reviewed in all aspects. samples were characterized by the x-ray diffractometry (xrd), the thermal analysis (tg, dsc), thefourier transform infra-red spectroscopy (ftir) and the scanning electron microscopy (sem).their structuredepends largely on the me...

Comparative study on Sea Surface Temperature: SST estimations among the conventional Multi-Channel Seat Surface Temperature: MCSST, split window method and the proposed Conjugate Gradient based method: CGM with Thermal Infrared Radiometer: TIR data through simulations is conducted. Utilizing the proposed linearized inversion of radiative transfer equation, SST can be estimated. SST estimation a...

the study area is the rahmat anticline. this is located in fars province (sw fold simple zagros belt). the aims of this study are morphotectonic studies and structural analysis in several parts of area. for this purpose: 1) morphotectonic indices, drainage basin shape index (bs), mountain front sinuosity index (smf) and valley floor width – height ratio (vf) were measured by digital elevation m...

We describe a class of continuously phase-modulated radiation pulses that result in coherent population inversion on resonance as well as over a large range of transition frequencies and radiation field strengths. This is a population-inversion analogy to self-induced transparency. Simulations of the inversion properties of' the modulated inversion pulse (MIP) are presented. It is shown that th...

beverage emulsions are systems that are composed of two liquids including oil and water which are prepared by homogenizing oil phase in an acidic aqueous phase. they must be stable in both concentrated and diluted form for a period of 6-12 months upon standing at room temperature. two immiscible phases contained systems are thermodynamically unsta-ble. in other words, they are vulnerable to bre...

TbMnO3 is an orthorhombic insulator where incommensurate spin order for temperature T(N)<41 K is accompanied by ferroelectric order for T<28 K. To understand this, we establish the magnetic structure above and below the ferroelectric transition using neutron diffraction. In the paraelectric phase, the spin structure is incommensurate and longitudinally modulated. In the ferroelectric phase, how...

the purpose of this study is numerical modeling of temperature variation of phases in a two phase regime in fluidized bed dryers including particles belonging to group d of geldart classification. the mass transfer between phases is not taken into consideration in this modeling which has been assumed in three- dimensional, unsteady, and two-phase regime.to verify the modeling we consider the do...
