Non-Bloch topological invariants in a non-Hermitian domain wall system [PDF]
Physical review B, 2019 We study non-Bloch bulk-boundary correspondence in a non-Hermitian Su-Schieffer-Heeger model in a domain-wall configuration where the left and right bulks have different parameters.

Domain Walls on the Brane [PDF]
, 1998 We show that all branes admit worldvolume domain wall solutions. We find one class of solutions for which the tension of the brane changes discontinuously along the domain wall. These solutions are not supersymmetric. We argue that there is another class

Domain-wall pinning and defect ordering in BiFeO3 probed on the atomic and nanoscale
Nature Communications, 2020 Electro-mechanical interactions between charged point defects and domain walls play a key role in the functional properties of bulk and thin-film ferroelectrics.

Domain wall encoding of discrete variables for quantum annealing and QAOA [PDF]
Quantum Science and Technology, 2019 In this paper I propose a new method of encoding discrete variables into Ising model qubits for quantum optimisation. The new method is based on the physics of domain walls in one-dimensional Ising spin chains.

International Journal of Modern Physics D, 2004 In this paper we investigate Charged Domain Walls (CDW's), topological defects that acquire surface charge density Q induced by fermion states localized on the walls. The presence of an electric and magnetic field on the walls is also discussed. We find a relation in which the value of the surface charge density Q is connected with the existence of ...

A Novel Design of a 3D Racetrack Memory Based on Functional Segments in Cylindrical Nanowire Arrays
Nanomaterials, 2020 A racetrack memory is a device where the information is stored as magnetic domains (bits) along a nanowire (track). To read and record the information, the bits are moved along the track by current pulses until they reach the reading/writing heads.

Current driven magnetization dynamics in ferromagnetic nanowires with Dzyaloshinskii-Moriya interaction [PDF]
, 2009 We study current induced magnetization dynamics in a long thin ferromagnetic wire with Dzyaloshinskii-Moriya interaction (DMI). We find a spiral domain wall configuration of the magnetization and obtain an analytical expression for the width of the ...

New Journal of Physics, 2019 Domain wall motion (DWM) by spin waves (SWs) in different waveforms in a magnetic nanostripe is investigated via micromagnetic simulations. Diversified DWMs are observed. It is found that SW harmonic drives DWM most efficiently and irregular SW may cause

Magnetic skyrmions and domain walls for logical and neuromorphic computing
Neuromorphic Computing and Engineering, 2023 Topological solitons are exciting candidates for the physical implementation of next-generation computing systems. As these solitons are nanoscale and can be controlled with minimal energy consumption, they are ideal to fulfill emerging needs for ...
