Coordination Symmetry Breaking of Single‐Atom Catalysts for Robust and Efficient Nitrate Electroreduction to Ammonia

Advances in Materials, 2022
Nitrate electrocatalytic reduction (NO3RR) for ammonia production is a promising strategy to close the N‐cycle from nitration contamination, as well as an alternative to the Haber–Bosch process with less energy consumption and carbon dioxide release ...

Rotation symmetry breaking in the normal state of a kagome superconductor KV3Sb5

Nature Physics, 2021
Recently discovered superconductors AV3Sb5 (A = K, Rb, Cs)1,2 provide a fresh opportunity to study correlation-driven electronic phenomena on a kagome lattice. The observation of an unusual charge density wave (CDW) in the normal state of all the members

Topological symmetry in quantum field theory

Quantum Topology, 2022
We introduce a definition and framework for internal topological symmetries in quantum field theory, including “noninvertible symmetries” and “categorical symmetries”.

Control of spin–orbit torques through crystal symmetry in WTe2/ferromagnet bilayers

Nature Physics, 2016
Recent discoveries regarding current-induced spin–orbit torques produced by heavy-metal/ferromagnet and topological-insulator/ferromagnet bilayers provide the potential for dramatically improved efficiency in the manipulation of magnetic devices. However,

Symmetry

The American mathematical monthly, 2000
The word "symmetry" is used in mathematics quite differently from in ordinary speech. In everyday life one applies it mainly to two-sided, right-left symmetry; but not so in mathematics.

Anti–parity-time symmetry in diffusive systems

Science, 2019
Making heat stand still Dissipative oscillating systems (waves) can be described mathematically in terms of non-Hermitian physics. When parity-time symmetric systems have dissipative components, the interplay between gain and loss can lead to unusual and
