Evidence for Itinerant Ferromagnetic Flat Bands Producing Large Transverse Responses

Advanced Materials, EarlyView.
Itinerant ferromagnetic flat bands are demonstrated in GdCo5 with a high Curie temperature of 940K, a stacked honeycomb–kagome lattice, through angle‐resolved photoemission spectroscopy and magneto‐thermoelectric measurements. These topological flat bands generate large Berry curvaturte, producing gigantic anomalous Nernst effect with record‐high ...

Spectrum of some triangulated categories

, 2012
In this paper, we compute the triangular spectrum (as defined by P. Balmer) of two classes of tensor triangulated categories which are quite common in algebraic geometry.

Abelian Signatures of Triangulated Categories: Derived Reconstruction Theorems

This paper introduces the concept of "abelian signatures" for triangulated categories as novel invariants aimed at providing deeper insights into their structure and enabling derived reconstruction. Triangulated categories, fundamental in modern algebraic geometry, representation theory, and topology, often conceal the underlying geometric or algebraic

The Derived Core of a Triangulated Category: Reconstructing Abelian Structures

Triangulated categories have emerged as a fundamental framework in modern algebra, algebraic geometry, and representation theory, providing a flexible setting to study derived functors and homological invariants. However, their inherent lack of kernels and cokernels often obscures the underlying abelian structures that are crucial for many applications.

LEAD: Literature Enhanced Ab Initio Discovery of Nitride Dusting Layers for Enhanced Tunnel Magnetoresistance and Lower Resistance Magnetic Tunnel Junctions

Advanced Materials, EarlyView.
Magnetic tunnel junctions (MTJs) using MgO tunnel barriers face challenges of high resistance‐area product and low tunnel magnetoresistance (TMR). To discover alternative materials, Literature Enhanced Ab initio Discovery (LEAD) is developed. The LEAD‐predicted materials are theoretically evaluated, showing that MTJs with dusting of ScN or TiN on ...

Compact generation of derived categories of stacks

, 2016
I will give a survey over recent results on derived categories of algebraic stacks with an emphasis on compact generation. In a loose sense, compact objects in the derived category is a replacement for ample line bundles on projective schemes. They also

Miniature Soft Robot With Magnetically Reprogrammable Surgical Functions

Advanced Materials, EarlyView.
Miniature soft robots have great prospects to revolutionize minimally invasive treatments. Here we present a miniature soft robot, which can be reprogrammed to perform five surgical functionalities with six‐degrees‐of‐freedom motions. This soft robot can prospectively make minimally invasive surgery considerably safer and painless, and enable ...

When Poor Exciton Dissociation Limits Photocurrents in Organic Solar Cells: Why Low Offset Non‐Fullerene Acceptor Blends Can't Be Efficient

Advanced Materials, EarlyView.
The energetic offset between the donor and the acceptor components in organic photoactive layers is central to the tradeoff between photovoltage and photocurrent losses. This Perspective covers the most important issues surrounding this topic in non‐fullerene acceptor blends, from the difficulty of accurately determining state energies and driving ...
