Transition to and from the skyrmion lattice phase by electric fields in a magnetoelectric compound
Nature Communications, 2016 Magnetoelectric material Cu2OSeO3hosts topologically-protected skyrmion magnetization textures, however only in an impractically narrow temperature range. Here, the authors demonstrate how the metastable skyrmion phase may be extended to low temperatures

Electron Holography: phases matter [PDF]
Microscopy, 2013 Essentially, all optics is wave optics, be it with light, X-rays, neutrons or electrons. The information transfer from the object to the image can only be understood in terms of waves given by amplitude and phase. However, phases are difficult to measure: for slowly oscillating waves such as sound or low-frequency electromagnetic waves, phases can be ...

Topological skyrmion phases of matter
Journal of Physics: Condensed Matter, 2023 Abstract We introduce topological phases of matter defined by skyrmions in the ground state spin—or pseudospin—expectation value textures in the Brillouin zone, the chiral and helical topological skyrmion phases of matter. These phases are protected by a symmetry present in centrosymmetric superconductors.

A Dual-Branch Lightweight Network for Multimodal Image Fusion with Mamba and INN
SensorsMultimodal image fusion aims to integrate complementary information from heterogeneous imaging modalities into a single informative image. However, many deep learning-based fusion methods rely on complex feature extractors, leading to high computational ...

Molecular beam deposition of a new layered pnictide with distorted Sb square nets
APL Materials, 2021 While the family of layered pnictides ABX2 (A—rare or alkaline earth metals, B—transition metals, and X—Sb/Bi) can host Dirac dispersions based on Sb/Bi square nets, nearly half of them have not yet been synthesized for possible combinations of the A and

CoRRWe identify fundamental limitations in machine learning by demonstrating that non-trivial mixed-state phases of matter are computationally hard to learn. Focusing on unsupervised learning of distributions, we show that autoregressive neural networks fail to learn global properties of distributions characterized by locally indistinguishable (LI) states.

Electric-field control of anomalous and topological Hall effects in oxide bilayer thin films
Nature Communications, 2018 Spintronic devices are typically controlled with magnetic fields or current injection but incorporating these mechanisms into high-density devices is difficult. Here the authors present an oxide device where the topological and anomalous Hall effects can

Observation of the quantum Hall effect in δ-doped SrTiO3
Nature Communications, 2016 Observation of quantum phenomena in correlated electron systems is challenging due to low mobility and high concentration of carriers. Here, Matsubara et al.

Zero-bias photocurrent in ferromagnetic topological insulator
Nature Communications, 2016 By magnetic-doping, the electronic band structure of a topological insulator can be significantly altered to yield functional behaviour. Here, the authors demonstrate a large photocurrent response, and its control, under zero-bias in an optimally ...
