Thick domain wall universes [PDF]

, 1999
We investigate the spacetime of a thick gravitating domain wall for a general potential $V(\Phi)$. Using general analytical arguments we show that all nontrivial solutions fall into two categories: those interpretable as an isolated domain wall with a ...

Current-Induced Domain Wall Motion in a Compensated Ferrimagnet. [PDF]

Physical Review Letters, 2018
Owing to the difficulty in detecting and manipulating the magnetic states of antiferromagnetic materials, studying their switching dynamics using electrical methods remains a challenging task.

THICKNESS DEPENDENCE OF MAGNETIC SWITCHING DYNAMICS OF BARIUM-FERRITE AS A HIGH-DENSITY PERPENDICULAR MAGNETIC STORAGE MEDIA

Jurnal Pendidikan Fisika Indonesia, 2017
Micromagnetic study of material thickness dependence of Barium-ferrite nano-dot magnetization dynamics has been performed. The used materials characteristics in this research represent the properties of Barium-ferrite.

Search for domain wall dark matter with atomic clocks on board global positioning system satellites [PDF]

Nature Communications, 2017
Cosmological observations indicate that dark matter makes up 85% of all matter in the universe yet its microscopic composition remains a mystery. Dark matter could arise from ultralight quantum fields that form macroscopic objects. Here we use the global

A domain wall in twisted M-theory

SciPost Physics, 2021
We study a four-dimensional domain wall in twisted M-theory. The domain wall is engineered by intersecting D6 branes in the type IIA frame. We identify the classical algebra of operators on the domain wall in terms of a higher vertex operator algebra,

Domain wall mobility in nanowires: transverse versus vortex walls

, 2003
The motion of domain walls in ferromagnetic, cylindrical nanowires is investigated numerically by solving the Landau-Lifshitz-Gilbert equation for a classical spin model in which energy contributions from exchange, crystalline anisotropy, dipole-dipole ...

Domain Wall Nonlinear Quantization [PDF]

Gravitation and Cosmology, 2021
The nonlinear quantization of the domain wall (relativistic membrane of codimension 1) is considered. The membrane dust equation is considered as an analogue of the Hamilton-Jacobi equation, which allows us to construct its quantum analogue. The resulting equation has the form of a nonlinear Klein-Fock-Gordon equation. It can be interpreted as the mean
