Exact physical quantities of the D 2 2 $$ {D}_2^{(2)} $$ spin chain model with generic open boundary conditions

Journal of High Energy Physics
We study the quantum integrable spin chain model associated with the twisted D 2 2 $$ {D}_2^{(2)} $$ algebra (or simply the D 2 2 $$ {D}_2^{(2)} $$ model) under generic open boundary conditions.

Chaotic string motion in a near pp-wave limit

Journal of High Energy Physics, 2023
We revisit classical string motion in a near pp-wave limit of AdS5 × S5. It is known that the Toda lattice models are integrable. But if the exponential potential is truncated at finite order, then the system may become non-integrable.

Gauge theories and integrable lattice models

Nuclear Physics B, 1989
Abstract Investigations of new knot polynomials discovered in the last few years have shown them to be intimately connected with soluble models of two dimensional lattice statistical mechanics. In this paper, these results, which in time may illuminate the whole question of why integrable lattice models exist, are reconsidered from the point of view ...

Tailoring Functional Properties of Ti–Ni–Cu Shape Memory Alloy Thin Films for MEMS Actuators

Advanced Engineering Materials, EarlyView.
A comprehensive study of critical parameters required to develop well‐performing Ti–Ni–Cu thin film shape memory alloy microactuators is provided. Materials science and device integration aspects are integrated by addressing structural and physical relationships using complementary characterization techniques as well as a practical fabrication solution

New construction of eigenstates and separation of variables for SU(N) quantum spin chains

Journal of High Energy Physics, 2017
We conjecture a new way to construct eigenstates of integrable XXX quantum spin chains with SU(N) symmetry. The states are built by repeatedly acting on the vacuum with a single operator B good(u) evaluated at the Bethe roots.

On different approaches to integrable lattice models

Journal of Physics A: Mathematical and Theoretical
Abstract Interaction-round the face (IRF) models are two-dimensional lattice models of statistical mechanics defined by an affine Lie algebra and admissibility conditions depending on a choice of representation of that affine Lie algebra. Integrable IRF models, i.e.

Lattice Integrable Models of Quantum Field Theory [PDF]

, 1993
The quantum inverse scattering method allows one to put quantum field theory models on a lattice in a way which preservesthe dynamicalstructure.The trace identitiesare discussedfor thesemodels.

Creep‐Induced Microstructural Evolution in an A2‐B2 Superalloy

Advanced Engineering Materials, EarlyView.
A 27.3Ta‐27.3Mo‐27.3Ti‐8Cr‐10Al (at.%) refractory high‐entropy alloy with precipitation‐strengthened A2‐B2 microstructure was studied by creep tests at 1030°C, which demonstrate a transition in deformation mechanisms in the range of 100–150 MPa applied stress. This is associated with changes in dislocation–precipitate interactions. Relevant deformation

Jordan blocks and the Bethe Ansatz II: The eclectic spin chain beyond K = 1

Journal of High Energy Physics, 2022
We continue the classification of the Jordan chains of the eclectic three state spin chain that we started in our previous article. Following the same steps, we construct the generalised eigenvectors of this spin chain by computing the strongly twisted ...

Ontology‐Aligned Structuring and Reuse of Multimodal Materials Data and Workflows Toward Automatic Reproduction

Advanced Engineering Materials, EarlyView.
Reproduction of stacking fault energy calculations from literature with a semi‐automated large language model‐assisted extraction procedure: extraction of simulation protocol, atomistic structures, computational parameters, and reported results, ontology alignment, knowledge graph construction and, finally, recomputation forvalidation.
