Biased domain walls

Physical Review D, 1996
Domain walls form naturally in the early Universe whenever a discrete symmetry is spontaneously broken at some phase transition. When each vacuum is populated equally, it is well known that the domain wall network comes to dominate the energy density of the Universe and causes excessive anisotropy in the cosmic microwave background.

Domain-wall structure and domain-wall strain

Journal of Applied Physics, 2003
Stresses and strains within domain walls are important for understanding the interaction of domain walls with point defects, and the surface structure of the domain walls. Unfortunately, attempts to determine these properties of the domain wall by diffraction or other methods fail because of the low resolution of the technique.

Optical domain walls

Physical Review E, 1994
Dynamical properties of the domain walls (DW's) in the light beams propagating in nonlinear optical fibers are considered. In the bimodal fiber, the DW, as it was recently demonstrated numerically, separates two domains with different circular polarizations. This DW is found here in an approxiate analytical form. Next, it is demonstrated that the fiber'

Domain Walls

2020
Technological evolution and revolution are both driven by the discovery of new functionalities, new materials and the design of yet smaller, faster, and more energy-efficient components. Progress is being made at a breathtaking pace, stimulated by the rapidly growing demand for more powerful and readily available information technology.

Ferroelectric and Antiferromagnetic Domain Wall

Journal of the Physical Society of Japan, 2003
Summary: It has been experimentally confirmed that the ferroelectric (FEL) and antiferromagnetic (AFM) order-parameter in hexagonal \(\text{YMnO}_3\) are coupled at the FEL domain boundary. A microscopic model for this clamping of the two order-parameters is proposed.

Domain Walls and Wall Structure

1991
The concept of a magnetic domain wall is as fundamental to the domain theory as the domains themselves. The original formulation of what we now call a Bloch Wall assumed an infinite sample, an energy of both exchange and anisotropy and recognized that the lowest energy would be when the demagnetizing field across the wall was zero.

Dynamics of thick domain walls

Physical Review D, 1989
The dynamics of thick domain walls are studied in the context of the classical field theory for a real scalar field. We treat, by numerically solving the equation of motion for the scalar field, the collision of two plane-symmetric walls as well as the collapse of walls that have spherical and cylindrical symmetry.

Construction of curved domain walls

Physical Review E, 2008
The evolution of the domain wall is reduced to the dynamics of the membrane. The rigorous construction of curved membranes in the real scalar field models with domain-wall solutions is presented. An example of the curved membrane is discussed in detail. The curved domain-wall solutions are constructed.
