Quadrupole topological phase and robust corner resonance in Kekulé hexagonal electric circuit

New Journal of Physics, 2020
Abstract Two-dimensional (2D) quadrupole topological insulators, featured by topologically protected 0D corner modes, have recently attracted tremendous interest in condensed matter and materials physics. Herein, we construct a specific electric circuit made of capacitors and inductors forming a 2D Kekulé hexagonal lattice for quadrupole

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 ...

Higher-order topological electric circuits and topological corner resonance on the breathing kagome and pyrochlore lattices [PDF]

Physical Review B, 2018
Electric circuits are known to realize topological quadrupole insulators. We explore electric circuits made of capacitors and inductors forming the breathing Kagome and pyrochlore lattices. They are known to possess three phases (trivial insulator, higher-order topological insulator and metallic phases) in the tight-binding model. The topological phase

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 ...

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.

Observation of Klein bottle quadrupole topological insulators in electric circuits

Journal of Applied Physics
The Klein bottle insulator phase plays a pivotal role in understanding higher-order topological phases. The insulator phase is characterized by a unique feature: A nonsymmorphic glide symmetry that exists within momentum space, rather than real space.
