Dynamic Dilatonic Domain Walls [PDF]

Nuclear Physics B, 1999
Motivated by the ``universe as a brane'' idea, we investigate the motion of a $(D-2)$-brane (or domain wall) that couples to bulk matter. Usually one would expect the spacetime outside such a wall to be time dependent however we show that in certain ...

Domain Walls are Diamagnetic [PDF]

Physics Letters B, 1996
It is shown that contrary to a recent claim in the literature, the domain walls made of scalar field are diamagnetic due to presence of massless fermionic modes on the wall. The diamagnetism vanishes at high temperature.

Tailoring elastic and inelastic collisions of relativistic antiferromagnetic domain walls [PDF]

Scientific Reports, 2023
Soliton-based computing relies on their unique properties for transporting energy and emerging intact from head-on collisions. Magnetic domain walls are often referred to as solitons disregarding the strict mathematical definition requiring the above ...

Ferroelectric polarization and magnetic structure at domain walls in a multiferroic film [PDF]

Nature Communications
Domain walls affect significantly ferroelectric and magnetic properties of magnetoelectric multiferroics. The stereotype is that the ferroelectric polarization will reduce at the domain walls due to the incomplete shielding of depolarization field or the

Giant conductivity of mobile non-oxide domain walls [PDF]

Nature Communications, 2021
Conductive domain walls have been usually found in ferroelectric oxides. Here, the authors report on giant conductivity of domain walls and their magnetically avalanche-like expulsion event in non-oxide ferroelectric GaV4S8, extending the source of ...

Direct observation of magnetic domain walls in glass-coated submicronic amorphous wires [PDF]

Scientific Reports
Results on the magnetic domain walls in rapidly solidified magnetostrictive and non-magnetostrictive amorphous submicronic wires are reported. Utilizing Lorentz transmission electron microscopy (LTEM) for the first time in this context, we have ...
