Electric Field Induced Collapse of Charge-Ordered Phase in Manganites [PDF]

open access: yes, 2006
The colossal electroresistance in manganites is a concomitant of the electric field induced insulator-to-metal phase transition. A phenomenological phase transition model is proposed to study this electric field induced collapse of charge-ordered phase ...

Computable Fields and Arithmetically Definable Ordered Fields [PDF]

open access: yesProceedings of the American Mathematical Society, 1970
Introduction. A computable field is one whose elements may be placed in one-one correspondence with the natural numbers in such a way that the number theoretic functions corresponding to the field operations are recursive. In the same vein a field is called arithmetically definable (AD for short) if its elements may be placed in one-one correspondence ...

Completeness of Ordered Fields and a Trio of Classical Series Tests

open access: yesAbstract and Applied Analysis, 2016
This article explores the fate of the infinite series tests of Dirichlet, Dedekind, and Abel in the context of an arbitrary ordered field. It is shown that each of these three tests characterizes the Dedekind completeness of an Archimedean ordered field;

Holographic conformal order in supergravity

open access: yesPhysics Letters B, 2021
We explore the embedding of the phenomenological holographic models describing thermal relativistic ordered conformal phases in R2,1 in SUGRA/String theory.

Plasmonic field guided patterning of ordered colloidal nanostructures

open access: yesNanophotonics, 2019
Nano-patterned colloidal plasmonic metasurfaces are capable of manipulation of light at the subwavelength scale. However, achieving controllable lithography-free nano-patterning for colloidal metasurfaces still remains a major challenge, limiting their ...

On the gauge chosen by the bosonic open string

open access: yesNuclear Physics B, 2017
String theory gives S matrix elements from which is not possible to read any gauge information. Using factorization we go off shell in the simplest and most naive way and we read which are the vertices suggested by string.

Diagnosing Magnetic Field Geometry in Blazar Jets Using Multi-Frequency, Centimeter-Band Polarimetry and Radiative Transfer Modeling

open access: yesGalaxies, 2020
We use multi-frequency linear polarization observations from the University of Michigan blazar program (UMRAO), in combination with radiative transfer simulations of emission from a relativistic jet, to investigate the time-dependent flow conditions ...

*-valuations and ordered *-fields [PDF]

open access: yesTransactions of the American Mathematical Society, 1980
We generalize elementary valuation theory to *-fields (division rings with involution), apply the generalized theory to the task of ordering *-fields, and give some applications to Hermitian forms.

Ideals in Ordered Γ-Semirings

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2018
In this paper, we introduce the notion of k-ideal, m−k ideal, prime ideal, maximal ideal, filter, irreducible ideal, strongly irreducible ideal in ordered Γ-semirings, study the properties of ideals in ordered Γ-semirings and the relations between them ...

Ordered intermetallic compounds combining precious metals and transition metals for electrocatalysis

open access: yesFrontiers in Chemistry, 2022
Ordered intermetallic alloys with significantly improved activity and stability have attracted extensive attention as advanced electrocatalysts for reactions in polymer electrolyte membrane fuel cells (PEMFCs).
