Structure and Topology of Band Structures in the 1651 Magnetic Space Groups

open access: yes, 2018
The properties of electrons in magnetically ordered crystals are of interest both from the viewpoint of realizing novel topological phases, such as magnetic Weyl semimetals, and from the applications perspective of creating energy-efficient memories.

Emergent Spin‐Glass Behavior in an Iron(II)‐Based Metal–Organic Framework Glass

open access: yesAdvanced Functional Materials, EarlyView.
A one‐pot, solvent‐free synthesis yields an Fe2+‐based metal‐organic framework (MOF) glass featuring a continuous random network structure. The material exhibits spin‐glass freezing at 14 K, driven by topological‐disorder and short‐range magnetic frustration, showcasing the potential of MOF glasses as a plattform for cooperative magnetic phenomena in ...

Fractal Symmetric Phases of Matter

open access: yesSciPost Physics, 2019
We study spin systems which exhibit symmetries that act on a fractal subset of sites, with fractal structures generated by linear cellular automata. In addition to the trivial symmetric paramagnet and spontaneously symmetry broken phases, we construct

Topological quantum paramagnet in a quantum spin ladder

open access: yes, 2017
It has recently been found that bosonic excitations of ordered media, such as phonons or spinons, can exhibit topologically nontrivial band structures.

Predicting Atomic Charges in MOFs by Topological Charge Equilibration

open access: yesAdvanced Functional Materials, EarlyView.
An atomic charge prediction method is presented that is able to accurately reproduce ab‐initio‐derived reference charges for a large number of metal–organic frameworks. Based on a topological charge equilibration scheme, static charges that fulfill overall neutrality are quickly generated.

Ground-state magnetic structures of topological kagome metals RV_{6}Sn_{6} (R=Tb,Dy,Ho,Er)

open access: yesPhysical Review Research
Magnetic kagome metals have attracted tremendous research interests recently, because they represent an ideal playground for exploring the fascinating interplay between their intrinsically inherited topologically nontrivial electron band structures ...

Erratum to: Numerical Representability of Ordered Topological Spaces with Compatible Algebraic Structure [PDF]

open access: yesOrder, 2011
Unfortunately, we found a significant omission in the article. In Definition 3.5 a condition was missing. That condition is important because it has a decisive influence on the proof of the main Theorem 3.14, as well as on the footnote linked to Definition 3.5.

Magnetic Force Microscopy Signatures of Higher‐Order Skyrmions and Antiskyrmions

open access: yesAdvanced Functional Materials, EarlyView.
Magnetic force microscopy operated under vacuum conditions enables the qualitative identification of higher‐order skyrmions and antiskyrmions in Co/Ni multilayers at room temperature. Distinct stray‐field contrast signatures arise from vertical Bloch lines and complex domain‐wall configurations.

Plasma photonic crystal ‘kaleidoscope’ with flexible control of topology and electromagnetism

open access: yesFrontiers of Optoelectronics
Continuous development of photonic crystals (PCs) over the last 30 years has carved out many new scientific frontiers. However, creating tunable PCs that enable flexible control of geometric configurations remains a challenge. Here we present a scheme to

Nematic Order, Plasmonic Switching and Self‐Patterning of Colloidal Gold Bipyramids

open access: yesAdvanced Science, 2021
Dispersing inorganic colloidal nanoparticles within nematic liquid crystals provides a versatile platform both for forming new soft matter phases and for predefining physical behavior through mesoscale molecular‐colloidal self‐organization.
