Generation of Electric Current by Magnetic Field at the Boundary: Quantum Scale Anomaly Versus Semiclassical Meissner Current Outside of the Conformal Limit

Advanced Physics Research, EarlyView., 2023
The paper discusses the role of scale anomaly in generating edge electric currents via the scale magnetic effect in scalar electrodynamics. Although the boundary electric current is much weaker than the Meissner current induced in superconducting materials, the scale anomaly can enhance conductivity near the boundary of the material.

Superconducting Lithium Hydride in a Chemical Capacitor Setup: A Theoretical Study. [PDF]

Chemphyschem
Metallization of bulk lithium hydride has never been achieved through pressure alone. Single‐layer lithium hydride sandwiched between two support layers may resist hole doping up to substantial levels, forming a two‐dimensional metal (Fermi surface shown).

Plasmonic Hot Spots on Topological Insulator Nanotips for Enhancing Light Interaction with MoS2 Atomic Monolayer [invited]

Advanced Photonics Research, EarlyView.
A pair of Sb2Te3 topological insulator (TI) nanotips is fabricated by using the focused ion beam lithography to demonstrate the plasmonic hot spot effect at the visible range. The strong enhancement of electric field can be generated on the TI nanotips due to the plasmonic effect, giving rise to the obvious improvement of photoluminescence emission ...

Packaging Metal Atomic Clusters for Universal and Robust Protection through Cluster Beam Process

Advanced Science, EarlyView.
Gas‐phase‐aggregated metal clusters are packaged and well‐protected in poly(methyl methacrylate) (PMMA) through controlled beam implantation. The packaged precise clusters show robust protection against oxidation and agglomeration. This protection also demonstrates universality, as it successfully protects metal clusters composed of various elements ...

Superconducting Carbon‐Cage Network with Tc of 109 K at Ambient Pressure

Advanced Science, EarlyView.
By introducing elemental and hole doping into a theoretically designed sp3‐hybridized C18 carbon cage, superconductivity with a transition temperature up to 109 K is predicted under ambient pressure. These findings offer a promising pathway for designing high‐Tc superconductors based on stable covalent carbon frameworks.

Probing Anisotropic Quasiparticle Dynamics and Topological Phase Transitions in Quasi‐1D Topological Insulator ZrTe5

Advanced Science, EarlyView.
This study reveals quasiparticle dynamics in ZrTe5. Polarization‐dependent measurements show transient reflectivity anisotropy arises from electron relaxation and lattice vibrations. The first dynamical evidence of a temperature‐induced Lifshitz transition is reported.

Unveiling the Fundamental Principles of Reconfigurable Resistance States in Silver/Poly(Ethylene Glycol) Nanofluids

Advanced Science, EarlyView.
The electrophoretic reorganization of Ag nanoparticles within a poly(ethylene glycol) leads to the formation of conductive bridges with reconfigurable resistance states. Diverse conduction characteristics of the bridge range between ohmic conduction, nonlinear tunneling, or space charge‐limited conduction, and high resistance states.

Ambient‐Pressure Superconductivity Onset at 10 K and Robust Tc under High Pressure in TiNbTaN3 Medium‐Entropy Nitride

Advanced Science, EarlyView.
The first observation of superconductivity in a bulk MEN TiNbTaN3 with Tc ≈ 10 K at ambient pressure and the electronic specific heat coefficient γ(H) exhibits nonlinear H‐dependence behavior, which is similar to other well‐studied multigap superconductors is reported.

3D Topological Inorganic Electrides: Screening, Properties, and Applications

Advanced Science, EarlyView.
In inorganic electrides, zero‐, one‐, and two‐dimensional (0D, 1D, and 2D) interstitial anionic electrons interconnect within lattice cavities, collectively forming a three‐dimensional (3D) network, further coupling magnetism and topological features, leading to the emergence of 3D topological inorganic electrides.

Thermal Control of Vortex Motion in Nanoscale Superconductors

Advanced Electronic Materials, EarlyView.
Vortices in superconducting film can be thermally steered by a local heating from a tip. The work shows that the vortex is attracted by the hot spot by a force that emulates an electric field resulting in a fictious Lorentz‐force on the vortex. Abstract Thermally induced motion of vortices in nanoscale superconductors (SCs) is investigated.
