Convex $L$-lattice subgroups in $L$-ordered groups [PDF]

open access: yesCategories and General Algebraic Structures with Applications, 2018
In this paper, we have focused to study convex $L$-subgroups of an $L$-ordered group. First, we introduce the concept of a convex $L$-subgroup and a convex $L$-lattice subgroup of an $L$-ordered group and give some examples.

Chiral Spin Liquid Phase of the Triangular Lattice Hubbard Model: A Density Matrix Renormalization Group Study

open access: yesPhysical Review X, 2020
Motivated by experimental studies that have found signatures of a quantum spin liquid phase in organic crystals whose structure is well described by the two-dimensional triangular lattice, we study the Hubbard model on this lattice at half filling using ...

The meet of locally connected group topologies

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1994
The collection of all group topologies on a given group is a complete lattice partially ordered by inclusion. The purpose of this paper is to develop a convenient method of defining the meet of an arbitrary collection of group topologies and demonstrate ...

End-member compounds of a 4-sublattice model of multicomponent BCC solid solutions

open access: yesData in Brief, 2018
The article presents ab initio calculated properties (total energies, lattice parameters, and elastic properties) for the complete set of 1540 end-member compounds within a 4-sublattice model of Fe-based solid solutions.

Critical phase induced by Berry phase and dissipation in a spin chain

open access: yesPhysical Review Research, 2023
Motivated by experiments on spin chains embedded in a metallic bath, as well as closed quantum systems described by long-range interacting Hamiltonians, we study a critical SU(N) spin chain perturbed by dissipation, or equivalently, after space-time ...

SSNMR confirms silicate ion substitution in the apatitic structure of 0.8wt% Si hydroxyapatite

open access: yesAcademia Materials Science, 2023
This study investigates the structural location of silicon present in ‘silicate-substituted’ apatite. It has been hypothesized that silicon is present in the form of silicate groups site-specifically substituted in the hydroxyapatite lattice ...

A characterisation of lattice-ordered abelian groups

open access: yesMathematische Zeitschrift, 1993
It is pointed out that it is possible to define the prime ideal spectrum of any ordered Abelian group with distributive ideal lattice, and that this provides a point of contrast between the Riesz interpolation property, which (at least in the case of a countable group) does not impinge on the spectrum, and the lattice property, which -- in the presence

Ectopic A-lattice seams destabilize microtubules [PDF]

open access: yes, 2014
Natural microtubules typically include one A-lattice seam within an otherwise helically symmetric B-lattice tube. It is currently unclear how A-lattice seams influence microtubule dynamic instability.

Structural, morphological and vibrational properties of Li4Ti5-xNbxO12 anode materials

open access: yesMaterials Science for Energy Technologies, 2022
The spinel structured chemical composition of Li4Ti5-xNbxO12 (0 ≤ x ≤ 0.1) anode materials are manufactured by solid state process. An organized exhibition of the outcomes of the structural, morphological and vibrational bonding nature of the negative ...
