This study reveals that higher shell S coordination can effectively modulate the spin state of FeN4 site via long‐range electronic interactions, giving rise to the oriented generation of singlet oxygen from peroxymonosulfate activation. Abstract Precise manipulation of coordination structure of single‐atom sites and establishment of schematic ...

Berry Curvature, Triangle Anomalies, and the Chiral Magnetic Effect in Fermi Liquids
In a three-dimensional Fermi liquid, quasiparticles near the Fermi surface may possess a Berry curvature. We show that if the Berry curvature has a nonvanishing flux through the Fermi surface, the particle number associated with this Fermi surface has a ...

Observation of Dirac-like energy band and ring-torus Fermi surface associated with the nodal line in topological insulator CaAgAs [PDF]
One of key challenges in current material research is to search for new topological materials with inverted bulk-band structure. In topological insulators, the band inversion caused by strong spin–orbit coupling leads to opening of a band gap in the ...

A metastable high‐vacancy concentration layered P3‐type Na0.5Cr0.5Ti0.5O2 negative electrode material has been synthesized from its K analogues P3‐type K0.5Cr0.5Ti0.5O2 using a facile room temperature ion‐exchange method. The P3‐type Na0.5Cr0.5Ti0.5O2 demonstrates a gravimetric capacity of 125 mA h g−1 and high‐rate performance (80% charging in 3 min ...

The shape of the Fermi surface
Abstract We show that in the surface region, where the matter density falls off, the local momentum distribution of a many Fermion system becomes anisotropic. The local Fermi surface has a predominantly prolate shape, with its long axis normal to the surface in both spherical and semi-infinite many Fermion systems.

Chiral Weyl Pockets and Fermi Surface Topology of the Weyl Semimetal TaAs.
Tantalum arsenide is a member of the noncentrosymmetric monopnictides, which are putative Weyl semimetals. In these materials, three-dimensional chiral massless quasiparticles, the so-called Weyl fermions, are predicted to induce novel quantum mechanical

Manipulating superconductivity in ruthenates through Fermi surface engineering [PDF]
The key challenge in superconductivity research is to go beyond the historical mode of discovery-driven research. We put forth a new strategy, which is to combine theoretical developments in the weak-coupling renormalization-group approach with the ...

Introducing a high density of dislocations led to an increase in photoconductivity by more than one order of magnitude in Fe‐doped SrTiO3. Detailed analysis, focusing on the quantum paraelectric state, reveals that increased photoconductivity results from a higher charge carrier generation rate due to new energy states induced by dislocations, possibly

Fermi Surface under Magnetism Instability [PDF]
In this paper, we study the fermionic excitations near the quantum criticality using gauge/gravity duality. This is motivated by exploring the Fermi surface evolution near the quantum criticality. We construct the gravity dual of "paramagnetic-nematic" phase transition in a continuum limit and study the Fermi surface evolution across this quantum phase

Unconventional Fermi surface in an insulating state [PDF]
Probing the insulating state of SmB6 When a metal is subjected to a strong magnetic field, its electrons start rearranging into new energy levels, causing its electronic properties to oscillate as a function of the field.
