Ferroelectric Altermagnetic Chern Insulator in magnetic field: electrical control of the Chern number

This paper proposes a theoretical model demonstrating that combining an external magnetic field, spin canting, and ferroelectric orbital hybridization in a d-wave altermagnet lifts degeneracy at the Γ\Gamma point, thereby enabling electric-field control of the Chern number and realizing a tunable Chern insulator with phases ranging from C=±1C = \pm 1 to C=±2C = \pm 2.

Robust Spin Logic Enabled by Generalized SU(2)\mathrm{SU}(2) Symmetry in pp-Wave Magnets

This paper demonstrates that tuning the intrinsic momentum-dependent exchange field of a 3D pp-wave magnet against gate-induced Rashba spin-orbit coupling establishes a generalized SU(2)\mathrm{SU}(2) symmetry, which protects a Persistent Spin Helix to enable robust, disorder-resilient spin-logic devices with high-visibility electrical conductance oscillations.

Interfacial Coupling and Sparse Intercalation of 7-Atom-Wide Armchair Graphene Nanoribbons by N-Heterocyclic Carbene Monolayers

This study demonstrates that the intercalation efficiency of N-heterocyclic carbene monolayers beneath 7-atom-wide armchair graphene nanoribbons on Au(111) is critically governed by the molecular adsorption geometry, where flat-lying methyl-substituted dimers enable partial decoupling while bulky isopropyl-substituted monomers prevent intercalation.

Gate-tunable spin-valley transport via carrier velocity in monolayer WSe2_2

This paper theoretically demonstrates that in monolayer WSe2_2, spin- and valley-resolved quantum transport can be precisely controlled through the combined modulation of barrier velocity and scalar potential, revealing strong anisotropy, resonant tunneling, and tunable polarized currents via an effective massive Dirac Hamiltonian framework.

Optimal control over the full counting statistics in a non-adiabatic pump

This paper introduces a systematic optimal control procedure to enhance the performance of non-adiabatic Thouless pumps by simultaneously optimizing average transport rates and minimizing noise, thereby enabling independent control over charge and spin currents and their fluctuations in quantum dot systems.

Spin current symmetries generated by GdFeCo ferrimagnet across its magnetisation compensation temperature

This study investigates the spin current symmetries in GdFeCo ferrimagnets across the magnetisation compensation temperature, revealing that spin Hall and spin anomalous Hall effect torques retain their signs due to distinct origins in Gd 5d and FeCo 3d electronic subsystems, respectively.

Unveiling Micrometer-Range Spin-Wave Transport in Artificial Spin Ice

This study demonstrates coherent micrometer-range spin-wave transport in a hybrid artificial spin ice system by leveraging exchange-mediated coupling and evanescent tunneling to overcome the limitations of weak dipolar interactions, thereby enabling the investigation of spin-wave phenomena in frustrated magnetic lattices for potential analog signal processing applications.

Anisotropic marginal Fermi liquid for Coulomb interacting generalized Weyl fermions

Using a large-NN renormalization group approach, this paper demonstrates that three-dimensional generalized Weyl semimetals with monopole charge n2n \ge 2 exhibit an anisotropic marginal non-Fermi liquid phase driven by amplified Coulomb interactions, characterized by intrinsically anisotropic screening and power-law quasiparticle suppression, in contrast to the isotropic behavior found in systems with n=1n=1.
