Spin liquid nature in the Heisenberg $J_{1}$-$J_{2}$ triangular antiferromagnet [PDF]
, 2016 We investigate the spin-$\frac{1}{2}$ Heisenberg model on the triangular lattice in the presence of nearest-neighbor $J_1$ and next-nearest-neighbor $J_2$ antiferromagnetic couplings. Motivated by recent findings from density-matrix renormalization group

Coherent control in atomic chains: To trap and release a traveling excitation
Physical Review Research, 2022 We introduce a protocol for dynamical dispersion engineering in an atomic chain formed by an ordered array of multilevel atoms with subwavelength lattice constant.

Three-sublattice order in the SU(3) Heisenberg model on the square and triangular lattice
, 2012 We present a numerical study of the SU(3) Heisenberg model of three-flavor fermions on the triangular and square lattice by means of the density-matrix renormalization group (DMRG) and infinite projected entangled-pair states (iPEPS).

Valuations of Lattice-Ordered Groups
Journal of Algebra, 1997 The authors study valuations on lattice-ordered groups with values in a lattice of order ideals of the root system of regular subgroups. They use these valuations to obtain new and old results for archimedean extensions and archimedean closures of lattice-ordered groups. In the penultimate section of their paper, they define \(\Delta\)-extensions and \(

Idempotent 2x2 matrices over linearly ordered abelian groups [PDF]
Categories and General Algebraic Structures with ApplicationsIn this paper we study multiplicative semigroups of $2\times 2$ matrices over a linearly ordered abelian group with an externally added bottom element. The multiplication of such a semigroup is defined by replacing addition and multiplication by join and

Spin liquid phase of the $S=\frac{1}{2}$ $J_1-J_2$ Heisenberg model on the triangular lattice
, 2015 We study the $S=1/2$ Heisenberg model on the triangular lattice with nearest neighbor interaction $J_1$ and next nearest neighbor interaction $J_2$ with the density matrix renormalization group.

Latent Heat Calculation of the 3D q=3, 4, and 5 Potts models by Tensor Product Variational Approach [PDF]
, 2002 Three-dimensional (3D) $q$-state Potts models ($q$=3, 4, and 5) are studied by the tensor product variational approach (TPVA), which is a recently developed variational method for 3D classical lattice models.

*-Maximum lattice-ordered groups
Rocky Mountain Journal of Mathematics, 2013 Denote by \(W\) the category of archimedean \(l\)-groups \(G\) with a distinguished positive weak order unit \(e_G\) (that is, \(e_G^\bot\equiv\{g:|g|\wedge e_G=0\}=\{0\}\)), and morphisms \(\varphi\colon G\to H\) the \(l\)-group homomorphisms with \(\varphi(e_G)=e_H\). For \(G\in |W|\), denote by \(G^*\equiv\{g\in G:\exists n\in\mathbb N\;|g|\leq ne_G\
