Imaging flat band electron hydrodynamics in biased bilayer graphene

Using a scanning superconducting magnetic sensor to image local current flow in dual-gated bilayer graphene, researchers identified distinct ballistic, hydrodynamic, and diffusive transport regimes, demonstrating that the flat band regime with its large effective mass enables ultra-short electron-electron scattering lengths (~50 nm) and strong nonlinearities, thereby paving the way for miniaturized electronic devices based on electron hydrodynamics.

Controlled localization of anyons in a graphene quantum Hall interferometer

This study demonstrates the controlled localization and manipulation of anyons in a bilayer graphene quantum Hall interferometer, observing hundreds of phase slips that confirm the presence of localized non-abelian e/4e/4 anyons and charge-e/2e/2 abelian excitations, marking a significant step toward realizing fault-tolerant topological qubits.

Hall conductance in a weakly time-reversal invariant open system

This paper demonstrates that a non-equilibrium open system with weak time-reversal symmetry can exhibit non-quantized Hall conductance without an external magnetic field, as interactions with bosonic degrees of freedom and an external reservoir induce a time-reversal-breaking self-energy in the fermionic subsystem, a phenomenon that requires wave-function renormalization effects beyond a simple mass term.

Linear response of the Chern insulator MnBi2_2Te4_4: A Wannier function approach

Using a Wannier function approach combined with density functional theory, this study calculates the optical properties and Chern numbers of MnBi2_2Te4_4 thin films, revealing that eleven septuple-layer films share the same Chern number as five-layer films and challenging previous reports of a higher Chern-number phase.

Optically Driven Orbital Hall Transport in Floquet Odd-Parity Collinear Altermagnets with High Chern Numbers

This paper demonstrates that circularly polarized light can induce high-Chern-number quantum anomalous Hall effects and controllable orbital Hall transport in two-dimensional collinear altermagnets like VSi2_2N4_4 through Floquet engineering of ff-wave odd-parity magnetism.

Anomalous Coulomb-Enhanced Charge Transport in Triangular Triple Quantum Dots Systems

Using the exact hierarchical equations of motion formalism, this study reveals that increasing Coulomb interaction in triangular triple quantum dot systems uniquely enhances stationary current through the interplay of interaction-induced energy shifts and quantum interference, contrasting with the current suppression typically seen in linear arrays.

Non-volatile Multistate Magnetic Switching via Spin-orbit Torque and Intrinsic Anisotropy

This paper demonstrates a robust, non-volatile multistate magnetic switch in a SrIrO₃/SrRuO₃ bilayer that utilizes spin-orbit torque and intrinsic fourfold anisotropy to achieve deterministic electrical control over four distinct magnetic states, thereby overcoming the density limitations of conventional bistate spintronic devices.
