Confinement Driven Spin‐Texture Evolution in Directly Written Nanomagnets
Advanced Functional Materials, EarlyView.Spin‐texture is directly written by triggering lattice ordering locally at the nanoscale. Geometric confinement drives the formation of spin‐textures such as Néel walls with perpendicular core spins, essential for technological applications. Abstract In low‐dimensional magnetic structures, magnetostatic energy minimization yields a uniform spin‐texture,

Symmetric Linear Backlund Transformation for Discrete BKP and DKP equation
, 1999 Proper lattices for the discrete BKP and the discrete DKP equaitons are determined. Linear B\"acklund transformation equations for the discrete BKP and the DKP equations are constructed, which possesses the lattice symmetries and generate auto-B\"acklund

Hamiltonian systems with a discrete symmetry
Journal of Differential Equations, 1981 AbstractIf ƒ: M → M is an antisymplectic involution of a symplectic manifold M then the fixed set of ƒ is a Lagrangian submanifold L ⊂ M. Moreover there exist cotangent bundle coordinates in a neighborhood of L in M such that ƒ in these coordinates maps a covector into its negative.

Breaking Discrete Symmetries in Broken Gauge Theories
, 2005 We study the spontaneous breaking of discrete symmetries in theories with broken gauge symmetry. The intended application is to CP breaking in theories with gauged flavor symmetries, but the analysis described here is preliminary. We dispense with matter

Advanced Functional Materials, EarlyView.Phase‐field modeling reveals the mechanisms behind short‐term ferroelectric imprint in Hf0.5Zr0.5O2 polycrystalline thin films. Combined with a charge trapping model, the proposed framework accurately reproduces coercive field shifts with pause time and their recovery through field cycling in polarization‐voltage measurements, offering valuable ...

Non-Universal Anomalies in Heterotic String Constructions
, 2012 We investigate anomalies on heterotic orbifolds and their blowups. We give a simple example of an orbifold blowup which contains anomalous U(1) symmetries that are canceled by axions which couple non-universally to the different gauge groups, thus ...

Peak‐in‐Valley Metal Nano‐Architectures via E‐Beam‐Guided Metal Oxide Redox
Advanced Functional Materials, EarlyView.Focused electron beam irradiation of nanoelectrosprayed water‐ammonia films enables the synthesis of topologically complex metal nanostructures via solvent‐mediated metal/metal‐ion redox control. Low ammonia favors radiolytic oxidation, etching copper.
