Tunneling magnetoresistance in a junction made of XX-wave magnets with X=p,d,f,g,iX=p,d,f,g,i

This paper derives a universal analytic formula for the tunneling magnetoresistance (TMR) in junctions of XX-wave magnets (including altermagnets), revealing that while their TMR ratio scales linearly with magnetization strength and is generally smaller than that of ferromagnets, their zero net magnetization makes them promising candidates for high-speed, ultra-dense memory applications.

Rapid Autotuning of a SiGe Quantum Dot into the Single-Electron Regime with Machine Learning and RF-Reflectometry FPGA-Based Measurements

This paper demonstrates a 2.2-fold acceleration in initializing SiGe quantum dots into the single-electron regime by combining a neural network-based autotuning algorithm with FPGA-accelerated RF-reflectometry measurements, which collectively reduced stability diagram acquisition time by a factor of 9.8.

Deterministic Switching of Perpendicular Ferromagnets by Higher harmonics of Spin-orbit Torque in Noncentrosymmetric Weyl Semimetals

This paper demonstrates that field-free deterministic switching of perpendicular ferromagnets can be achieved in noncentrosymmetric Weyl semimetals, such as PrAlGe, by leveraging higher-order harmonics of spin-orbit torque to create new stable magnetization states, even in the presence of in-plane mirror symmetries.

Characterizing topology at nonzero temperature: Topological invariants and indicators in the extended SSH model

This paper characterizes topology in the Su-Schrieffer-Heeger chain at nonzero temperature by comparing three complementary diagnostics for mixed Gaussian states: the ensemble geometric phase, local twist operators, and a generalized local chiral marker, ultimately proposing practical local indicators that remain robust in the thermodynamic limit.

Controlled topological dilution drives cooperative glassy dynamics in artificial spin ice

This study demonstrates that controlled topological dilution via random decimation in artificial square spin ice systematically increases frustration and configurational entropy, driving a transition from long-range order to a cooperative glassy magnetic state characterized by aging, dynamical heterogeneity, and Vogel-Fulcher-type freezing.

Enhanced enantiomer discrimination with chiral surface plasmons

This paper demonstrates that surface plasmons supported by two-dimensional interfaces with electric and chiral conductivities enable significantly more efficient enantiomer discrimination than chiral optical cavities, achieving nearly an order-of-magnitude improvement through stronger field confinement and a geometric advantage that couples to dipole projections across an entire plane.

Nonlinear thermal gradient induced magnetization in dd^{\prime }, gg^{\prime } and ii^{\prime } altermagnets

This paper demonstrates that a finite magnetization can be induced by a second-order nonlinear temperature gradient in dd^{\prime }, gg^{\prime }, and ii^{\prime } altermagnets due to their specific spin-split band structures, whereas such a response is absent in their dd, gg, and ii counterparts as well as in various odd-parity magnets.

Room Temperature Anisotropic Photoresponse in Low-Symmetry van der Waals Semiconductor CrPS4_4

This paper demonstrates that the low-symmetry van der Waals semiconductor CrPS4_4 exhibits pronounced room-temperature optical and optoelectronic anisotropy, including strong linear dichroism and polarization-sensitive photocurrents driven by Cr3+^{3+} d-orbital transitions, establishing it as a promising platform for narrow-band polarized photodetectors and 2D spintronic devices.
