Recent Progress on Non-Conventional Microfabricated Probes for the Chronic Recording of Cortical Neural Activity
Microfabrication technology for cortical interfaces has advanced rapidly over the past few decades for electrophysiological studies and neuroprosthetic devices offering the precise recording and stimulation of neural activity in the cortex. While various cortical microelectrode arrays have been…

Spin Dynamics of Triple-Q Magnetic Orderings in a Triangular Lattice: Implications for Multi-Q Orderings in General Two-Dimensional Lattices
Multi-Q magnetic structures on two-dimensional (2D) lattices provide a key route to realizing topological physics in 2D magnetism. A major experimental challenge is to unambiguously confirm their formation by excluding the possibility of topologically trivial multidomain single- or double-Q…

Giant Magnetic Anisotropy in the Atomically Thin van der Waals Antiferromagnet FePS3
Abstract Van der Waals (vdW) magnets are an ideal platform for tailoring 2D magnetism with immense potential for spintronics applications and are intensively investigated. However, little is known about the microscopic origin of magnetic order in these antiferromagnetic systems. X‐ray photoemission…

Sharp spectroscopic fingerprints of disorder in an incompressible magnetic state
Abstract Disorder significantly impacts the electronic properties of conducting quantum materials by inducing electron localization and thus altering the local density of states and electric transport. In insulating quantum magnetic materials, the effects of disorder are less understood and can…

Kitaev interaction and proximate higher-order skyrmion crystal in the triangular lattice van der Waals antiferromagnet NiI 2
Abstract Topological spin textures are a spectacular manifestation of the chirality of the magnetic nanostructures protected by topology. Most known skyrmion systems are restricted to a topological charge of one, require an external magnetic field for stabilization, and are only reported in a few…

Tetrahedral triple-Q magnetic ordering and large spontaneous Hall conductivity in the metallic triangular antiferromagnet Co1/3TaS2
Abstract The triangular lattice antiferromagnet (TLAF) has been the standard paradigm of frustrated magnetism for several decades. The most common magnetic ordering in insulating TLAFs is the 120° structure. However, a new triple-Q chiral ordering can emerge in metallic TLAFs, representing the…

Targeting the microglial phosphatidylethanolamine synthesis pathway promotes GABARAP-associated phagocytosis and Aβ clearance in Alzheimer’s disease
Abstract Alzheimer’s disease (AD) is a major cause of dementia and a prevalent age-related neurodegenerative disorder characterized by progressive cognitive impairment and memory loss. Although metabolic activation or dysfunction of microglia is implicated in AD pathogenesis, the phospholipid…

Field-induced quantum spin disordered state in spin-1/2 honeycomb magnet Na2Co2TeO6
The honeycomb lattice with a spin-orbit interaction can give rise to exotic quantum states. With the measurements of bulk properties and inelastic neutron scattering, Lin et al demonstrate the existence of a field induced spin-disordered state in Na2Co2TeO6 and extend the Kitaev model to 3d system.
