Digitizing lattice gauge theories in the magnetic basis: reducing the breaking of the fundamental commutation relations

European Physical Journal C: Particles and Fields
We present a digitization scheme for the lattice $${\textrm{SU}}(2)$$ SU ( 2 ) gauge theory Hamiltonian in the magnetic basis, where the gauge links are unitary and diagonal.

Current Control of Spin Helicity and Nonreciprocal Charge Transport in a Multiferroic Conductor

Advanced Materials, EarlyView.
A conducting multiferroic state of spin origin with both electronic polarity (P) and magnetization (M) can be controlled and detected by electric current in a high‐temperature helimagnet YMn6Sn6. The underlying concept is the coupling of the electric current with the toroidal moment T∼P×M$\bm{T}\sim \bm{P}\ensuremath{\times{}}\bm{M}$.

Serrated Leaf‐Like N‐Doped Copper Sulfide Enabling Bifunctional Oxygen Reduction/Evolution via Dual‐Mode Cathode Reactions for High Energy Density and Cycle Stability in Zinc–Air Batteries

Advanced Science, EarlyView.
A serrated leaf‐like nitrogen‐doped copper sulfide (N‐CuS) cathode with hybridized N 2p – S 3p orbitals is presented, mesopores for oxygen transport, and a five times larger electrochemical active surface area than Cu. In aerobic conditions, a zinc–air battery with N‐CuS achieves 788 mAh g⁻¹ and 916 Wh kg⁻¹, outperforming Pt/C+RuO₂.

Pyridine‐Fused Bis(azacorrole)s: Easily Accessible NIR III Absorbing Cation Radicals and Biradicaloids of Antiaromatic Ground State

Advanced Science, EarlyView.
A series of pyridine‐fused hetero‐ and homodimers containing azacorrole moiety is obtained. The spectral, redox, and magnetic properties of the bis(azacorrole)s reflect an electron‐donating character of these systems and interaction between the subunits which depends on the substitution pattern.

High Radiation Resistance in the Binary W‐Ta System Through Small V Additions: A New Paradigm for Nuclear Fusion Materials

Advanced Science, EarlyView.
Refractory high‐entropy alloys exhibit superior radiation tolerance, but face fabrication challenges due to complex compositions. It is demonstrated that reducing the number of alloying elements does not compromise radiation resistance in a novel W‐Ta‐V highly‐concentrated refractory alloy.

Gauge Equivariant Neural Networks for 2+1D U(1) Gauge Theory Simulations in Hamiltonian Formulation [PDF]

arXiv, 2022
Gauge Theory plays a crucial role in many areas in science, including high energy physics, condensed matter physics and quantum information science. In quantum simulations of lattice gauge theory, an important step is to construct a wave function that obeys gauge symmetry.

Reversal of Spin‐Torque Polarity with Inverting Current Vorticity in Composition‐Graded Layer at the Ti/W Interface

Advanced Electronic Materials, EarlyView.
In compositional gradient materials, variations in electrical conductivity through the film thickness create a gradient in the electric current, resulting in vorticity. This vorticity acts like a magnetic field, whose gradient drives the generation of spin current.
