Advanced Functional Materials, EarlyView.The THz drive of the Mott insulating state of a rare‐earth nickelate induces instantaneous insulator‐metal transition via quantum tunneling of valence electrons across the bandgap. This transition is pure electronic and highly non‐thermal, which may find its applications in ultrafast opto‐electronics with enhanced performance and minimal device size ...

Space, matter and topology [PDF]
Nature Physics, 2016 An old branch of mathematics, Topology, has opened the road to the discovery of new phases of matter. A hidden topology in the energy spectrum is the key for novel conducting/insulating properties of topological matter.

High‐Entropy Magnetism of Murunskite
Advanced Functional Materials, EarlyView.The study of murunskite (K2FeCu3S4) reveals that its magnetic and orbital order emerges in a simple I4/mmm crystal structure with complete disorder in the transition metal positions. Mixed‐valence Fe ions randomly occupy 1/4 of the tetrahedral sites, with the remaining 3/4 being filled by non‐magnetic Cu+ ions.

, 2010 It seems to be a common belief that the space in which we live is a space-time manifold of dimension at least four. In the present article we wish to draw attention to a slightly different possibility - a space-time pseudomanifold (or even a generalized pseudomanifold of one dimension or another).

On resolvability of topological spaces
Topology and its Applications, 2002 AbstractResolvability of spaces whose extent (spread) is less than the dispersion character is investigated. A space X with a π-network of regular closed subsets such that Δ(X)>pext(X) is ℵ0-resolvable, and a space Y such that Δ(Y)>ps(Y) is maximally resolvable. In particular, assuming the negation of the continuum hypothesis, a (hereditarily) Lindelöf

Advanced Functional Materials, EarlyView.A spin group (SG)‐based mechanism is proposed to realize a single pair of Weyl points. PT‐symmetric nodal lines (NLs) persist under T‐breaking, protected by the combination of SG and P symmetry. When considering spin‐orbit coupling, the SG‐protected NL will split into Weyl points, which will also induce anomalous transport phenomena arising from ...

Fractional Skyrmion Tubes in Chiral‐Interfaced 3D Magnetic Nanowires
Advanced Functional Materials, EarlyView.In chiral 3D helical magnetic nanowires, the coupling between the geometric and magnetic chirality provides a way to create topological spin states like vortex tubes. Here, it is demonstrated how the breaking of this coupling in interfaced 3D nanowires of opposite chirality leads to even more complex topological spin states, such as fractional ...

Heliyon, 2022 In the present paper, detailed properties of soft submaximal topological spaces have been discussed. It starts by examining how well soft submaximal spaces behave when subjected to some operations, such as: taking soft subspaces, soft products, soft ...
