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

Physical 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
International 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
Data 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
Physical 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 ...

Amalgamations of lattice ordered groups [PDF]
Transactions of the American Mathematical Society, 1972 The author considers the problem of determining whether certain classes of lattice ordered groups (I-groups) have the amalgamation property. It is shown that the classes of abelian totally ordered groups (ogroups) and abelian i-groups have the property, but that the class of i-groups does not.

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

Charge order induced by electron-lattice interaction in NaV2O5
, 2005 We present Density Matrix Renormalization Group calculations of the ground-state properties of quarter-filled ladders including static electron-lattice coupling. Isolated ladders and two coupled ladders are considered, with model parameters obtained from
