Linearly Polarized Light-Induced Anomalous Hall Effect and Topological Phase Transitions in an Altermagnetic Topological Insulator

This study demonstrates that periodically driven linearly polarized light can uniquely induce an anomalous Hall effect and drive topological phase transitions in altermagnetic topological insulators by breaking their intrinsic symmetries, a phenomenon absent in conventional antiferromagnets, thereby offering a robust method for distinguishing these materials and enabling dissipationless spintronic applications.

Altermagnets Enable Gate-Switchable Helical and Chiral Topological Transport with Spin-Valley-Momentum-Locked Dual Protection

This paper establishes a unified framework in altermagnets, specifically identifying monolayer V2STeO and VO families, where a gate-tunable potential enables the electrical switching between robust helical and chiral topological transport phases via spin-valley-momentum-locked edge states.

Methods for characterization of atomic-scale field emission point-electron-source

This paper introduces a new experimental method using field ion and field electron microscopes to characterize atomic-scale field emission sources, demonstrating that the Murphy and Good theory yields significantly more accurate emission area measurements than simplified Fowler-Nordheim analysis and enabling the deduction of key beam properties.

Tomographic collective modes in a magnetic field

This paper investigates the transition from tomographic to conventional transport in two-dimensional Fermi liquids under a magnetic field by using a numerically exact solution of the linearized Boltzmann equation to demonstrate that a critical magnetic field causes one of two diffusive tomographic collective modes to disappear, leaving a remaining mode that becomes increasingly hydrodynamic at higher fields.

Deterministic Electrical Switching in Altermagnets via Surface Antisymmetry Groups

This paper establishes symmetry-based design rules using surface antisymmetry groups to identify specific surface orientations of centrosymmetric $d$ -wave altermagnets that enable deterministic electrical switching of the Néel vector via robust interfacial staggered fields and transverse spin currents.

Nanoscale Electronic Phase Separation Driven by Fe-site Ordering in Fe\textsubscript{5-x}GeTe\textsubscript{2}

By combining high-resolution scanning tunneling microscopy with density functional theory, this study reveals that Fe-site ordering in the van der Waals ferromagnet Fe $_{5-x}$ GeTe $_2$ drives nanoscale electronic phase separation, where ordered Fe(1) domains exhibit metallic behavior while deficient regions display pseudogapped states due to symmetry-allowed Fe 3d-Te 5p orbital hybridization.

Unifying description of competing chiral and nematic superconducting states in twisted bilayer graphene

This paper establishes a unified framework for electron- and phonon-driven superconductivity in twisted bilayer graphene, revealing that momentum-space frustration of locally preferred nematic orders can stabilize a chiral ground state with unpaired flat bands at large fillings or weak interactions.

Observation of first- and second-order dissipative phase transitions in a two-photon driven Kerr resonator

This paper presents the first comprehensive experimental and theoretical analysis of both first- and second-order dissipative phase transitions in a two-photon driven Kerr superconducting resonator, characterizing critical dynamics such as hysteresis and symmetry breaking to validate Liouvillian spectral theory for engineering criticality in quantum information applications.

Probing Boron Vacancy Defects in hBN via Single Spin Relaxometry

This paper demonstrates a nanoscale sensing technique that utilizes a single nitrogen-vacancy center in diamond to detect and map boron vacancy defects in hexagonal boron nitride by measuring changes in spin relaxation time ( $T_1$ ) caused by cross-relaxation, thereby enabling optical-free characterization of 2D spin systems beyond the diffraction limit.
