Despite multiple efforts, there exist many unsolved fundamental problems related with detection and analysis of internal polarization structure phase transitions in ferroelectric domain walls. Their solution can be very important for the progress wall nanoelectronics applications advanced memories other information technologies. Here, we theoretically study features walls, which are potentially...

Cosmic domain walls are harmless, provided that their tension decreases with expansion of the Universe. This setup can be realized, if scale spontaneous symmetry breaking is induced dynamically through interaction hot primordial plasma. In case, wall attain large values in early Universe without any conflict observations. Owing to initial tension, these topological defects may serve as a powerf...

One-point functions of local operators are studied, at weak and strong coupling, for the ABJM theory in presence a 1/2 BPS domain wall. In underlying quantum spin chain wall is represented by boundary state which we show integrable yielding compact determinant formula one-point generic operators.

The atomic-scale structural and electric parameters of the 90° domain-walls in tetragonal ferroelectrics are of technological importance for exploring the ferroelectric switching behaviors and various domain-wall-related novel functions. We have grown epitaxial PbTiO3/SrTiO3 multilayer films in which the electric dipoles at 90° domain-walls of ferroelectric PbTiO3 are characterized by means of ...

To better understand the response of domain walls to current-induced spin transfer torques, we have directly imaged the internal magnetic structure of domain walls in current-carrying ferromagnetic nanostripes. Domain wall images were acquired both while a constant current was flowing through the wire, and after applying current pulses. Domain walls ranging from vortex walls in wide 1 m wires t...
