Gravitational waves from domain wall collapse, and application to nanohertz signals with QCD-coupled axions [PDF]
Physics Letters B, 2023 We study for the first time the gravitational waves generated during the collapse of domain walls, incorporating the potential bias in the lattice simulations. The final stages of domain wall collapse are crucial for the production of gravitational waves,

Physical Review D, 2003 We construct lattices with alternating kinks and anti-kinks. The lattice is shown to be stable in certain models. We consider the forces between kinks and antikinks and find that the lattice dynamics is that of a Toda lattice. Such lattices are exotic metastable states in which the system can get trapped during a phase transition.

Physical Review D, 2021 We construct a new holographic description of QCD using domain wall fermions. The construction consists of probe D7 branes in a D5 brane geometry describing quarks on a 4+1d defect in a 5+1d gauge theory. We then compactify one dimension of the D5 to introduce confinement in the gauge degrees of freedom.

Supersymmetric domain walls [PDF]
Physical Review D, 2012 We classify the half-supersymmetric "domain walls", i.e. branes of codimension one, in toroidally compactified IIA/IIB string theory and show to which gauged supergravity theory each of these domain walls belong. We use as input the requirement of supersymmetric Wess-Zumino terms, the properties of the E11 Kac-Moody algebra and the embedding tensor ...

Spinor domain wall and test fermions on an arbitrary domain wall
European Physical Journal C: Particles and Fields, 2023 We consider a spinor domain wall embedded in a five-dimensional spacetime with a nondiagonal metric. The corresponding plane symmetric solutions for linear and nonlinear spinor fields with different parameters are obtained.

Magnetic domains and domain wall pinning in atomically thin CrBr3 revealed by nanoscale imaging
Nature Communications, 2021 The emergence of atomically thin van der Waals magnets provides a new platform for the studies of two-dimensional magnetism and its applications. However, the widely used measurement methods in recent studies cannot provide quantitative information of ...

Micromagnetic Simulation of Round Ferromagnetic Nanodots with Varying Roughness and Symmetry
Condensed Matter, 2021 Magnetic nanodots are of high interest for basic research due to their broad spectrum of possible magnetic states and magnetization reversal processes.

Observation of domain wall bimerons in chiral magnets [PDF]
Nature Communications, 2020 Topological defects embedded in or combined with domain walls have been proposed in various systems, some of which are referred to as domain wall skyrmions or domain wall bimerons. However, the experimental observation of such topological defects remains
