Band Topology or Geometry?

, 2011
The study of topology of energy bands in solid has always been interesting and fruitful. Historically, Thouless et al proposed the TKNN number or Chern number of the energy bands to explain the quantization of Hall conductance in the integer quantum Hall effect. Recently, Z2 topological insulators have been intensively studied and similarly topological

Reconfigurable 3D Magnetic Nanoarchitectures

Advanced Functional Materials, EarlyView.
This experimental study confirms that 3D magnetic tetrapods grown by focused electron beam‐induced deposition exhibit sequential, controllable magnetization reversal in the individual nanowire legs. The magnetic state of the nanoarchitecture can be controlled individually, on‐demand, through a variation of the direction and magnitude of the applied ...

Ce3+‐Activated Lithium Rare‐Earth Oxonitridolithosilicates: A New Class of LED Phosphors with Similarities to Garnets

Advanced Functional Materials, EarlyView.
Garnet‐like luminescence upon Ce3+‐activation is found in the first six representatives Li9RESi4N4O8 (RE = Y, La, Gd, Dy, Yb, Lu) of the substance class of lithium rare‐earth oxonitridolithosilicates, which also show a novel structure type. High‐temperature solid‐state synthesis yielded crystalline samples for single‐crystal X‐ray diffraction‐based ...

Realization of Complex‐Shaped Magnetic Nanotubes with 3D Printing and Electrodeposition

Advanced Functional Materials, EarlyView.
Complex‐shaped magnetic nanotubes were fabricated by coating three‐dimensional nanoscaffolds fabricated with focused electron beam induced deposition with a magnetic coating via electrodeposition. X‐ray magnetic microscopy and simulations revealed an azimuthal magnetic configuration within the nanotubes and pinning of domain walls at curved vertices ...

Peptide Sequencing With Single Acid Resolution Using a Sub‐Nanometer Diameter Pore

Advanced Functional Materials, EarlyView.
To sequence a single molecule of Aβ1−42–sodium dodecyl sulfate (SDS), the aggregate is forced through a sub‐nanopore 0.4 nm in diameter spanning a 4.0 nm thick membrane. The figure is a visual molecular dynamics (VMD) snapshot depicting the translocation of Aβ1−42–SDS through the pore; only the peptide, the SDS, the Na+ (yellow/green) and Cl− (cyan ...

Topology change and non-geometry at infinite distance

Journal of High Energy Physics
The distance conjecture diagnoses viable low-energy effective realisations of consistent theories of quantum gravity by examining their breakdown at infinite distance in their parameter space. At the same time, infinite distance points in parameter space

Reconfigurable Metamirrors Based on Compliant Mechanisms

Advanced Functional Materials, EarlyView.
Providing the basis for numerous practical applications, the reconfigurability of metadevices is of great importance. Through the integration of controlled mechanical deformation with chiral meta‐atoms, a compliant mechanism based metamirror is demonstrated for active control over the polarization of electromagnetic waves.
