W $$ \mathcal{W} $$ -algebra modules, free fields, and Gukov-Witten defects

Journal of High Energy Physics, 2019
We study the structure of modules of corner vertex operator algebras arrising at junctions of interfaces in N = 4 $$ \mathcal{N}=4 $$ SYM. In most of the paper, we concentrate on truncations of W 1 + ∞ $$ {\mathcal{W}}_{1+\infty } $$ associated to the ...

Miura-Like Free Field Realization Of Fermionic Casimir WB(3) Algebras [PDF]

, 1998
Starting from the well-known quantum Miura-like transformation for the non simply-laced Lie algebras B(3),we give an explicit construction of the Casimir WB(3) algebras.We reserve the notation WB(N) for the Casimir W algebras of type W(2,4,6,...,2N,N+1/2)

Complex KdV rogue waves from gauge-Miura transformation

Journal of Physics: Conference Series, 2023
Abstract The gauge-Miura correspondence establishes a map between the entire KdV and mKdV hierarchies, including positive and also negative flows, from which new relations besides the standard Miura transformation arise. We use this correspondence to classify solutions of the KdV hierarchy in terms of elementary tau functions of the mKdV

Multiband Switchable Microwave Absorbing Metamaterials Based on Reconfigurable Kirigami–Origami

Advanced Functional Materials, EarlyView.
A reconfigurable metamaterial featuring tunable microwave‐absorbing and load‐bearing performance is proposed. Stretchable kirigami and bistable origami configurations are integrated as actuating components, and the synergistic deformation mechanisms are systematically analyzed.

Quantum $W_N$ Algebras and Macdonald Polynomials

, 1995
We derive a quantum deformation of the $W_N$ algebra and its quantum Miura transformation, whose singular vectors realize the Macdonald polynomials.Comment: LaTeX file, 17-pages, no-figures, a reference ...

Integrable maps in 4D and modified Volterra lattices [PDF]

Open Communications in Nonlinear Mathematical Physics
In recent work, we presented the construction of a family of difference equations associated with the Stieltjes continued fraction expansion of a certain function on a hyperelliptic curve of genus $g$. As well as proving that each such discrete system is

Monolithic 3D Printing of Origami‐Inspired Soft Robotics from Sustainable Bio‐Based Resin

Advanced Science, EarlyView.
This work develops a photocurable, bio‐based resin from soybean oil for the monolithic fabrication of sustainable soft robots via Digital Light Processing. An origami‐inspired, vacuum‐actuated soft gripper is designed and fabricated, enabling reliable operation despite the material's lower elongation.

Control of Covalent Bond Enables Efficient Magnetic Cooling. [PDF]

Adv Mater
Giant and reversible magnetocaloric effect (MCE) is achieved by tuning covalency through sub‐unit‐cell chemical engineering, establishing a novel design principle for effective hysteresis control in magnetocaloric materials. Abstract Magnetic cooling, harnessing the temperature change in matter when exposed to a magnetic field, presents an energy ...
