Projected logical ensembles in surface codes via the random-matrix theory of quantum dots

This paper establishes a fundamental connection between quantum error correction and mesoscopic physics by demonstrating that the statistical properties of post-measurement logical states in surface codes under uniform Pauli-XX rotations are isomorphic to chaotic scattering matrices in quantum dots, thereby revealing a universal random-matrix ensemble governed by Altland-Zirnbauer symmetry classes.

Operator ordering as an emergent gauge field in twisted bilayer graphene: singular spectral signatures at the magic angle

This paper proposes that a Hermitian ordering correction to the Dirac Hamiltonian in magic-angle twisted bilayer graphene generates an emergent Aharonov-Bohm flux, resulting in a predicted asymmetric double-peak spectral signature at AB/BA stacking points that explains existing discrepancies between STM data and standard theoretical models.

Distinguishing Majorana zero modes from trivial defect states on the surface of the iron-based superconductor Fe(Te,Se)

Using spin-polarized scanning tunneling spectroscopy, this study demonstrates that near-zero-energy localized states observed on the surface of the iron-based superconductor Fe(Te,Se) are topologically trivial Yu-Shiba-Rusinov states rather than Majorana zero modes, highlighting the critical role of spin-dependent analysis in distinguishing true topological signatures from trivial defect states.

Anomalous Pairing Currents and a Second Topological Edge Channel in Bosonic Lattices

This paper demonstrates that bosonic pairing in a 2D kagome lattice generates a distinct, tunable chiral pairing current channel alongside the conventional hopping current, creating a unique topological edge response with no analogue in particle-conserving systems that is directly testable in photonic and superconducting platforms.

Helical Dirac Current with Local Coupling to a Chiral Potential

This paper demonstrates that exact Dirac eigenstates in cylindrical confinement possess a helical current texture that, when coupled to a static chiral scalar potential, generates a purely local, spin-selective interaction with a geometric selection rule, providing a foundational mechanism for spin-polarization phenomena like CISS without requiring external magnetic fields or spin-orbit coupling.

Atomic-scale sensing of photoexcitation processes in electronically isolated molecules via atomic force microscopy

This paper introduces a photoexcitation single-charge atomic force microscopy (PE-AFM) technique that synchronizes laser pulses with tip oscillation to detect photoexcitation in single molecules on non-conductive films with angstrom-scale resolution, revealing sub-molecular contrast indicative of long-lived quadruplet excited states.

Graphene Josephson diodes from inherent asymmetric disorder

This paper demonstrates that unavoidable long-range disorder in graphene Josephson junctions breaks inversion symmetry to produce a supercurrent rectification effect with over 20% efficiency under a small out-of-plane magnetic field, establishing a pathway for graphene-based Josephson diodes.

AC-flux-driven SQUID diode spectroscopy as a probe of current-phase relations

This paper proposes and validates a method to unambiguously extract individual current-phase relation harmonics in asymmetric SQUIDs by analyzing the distinct Bessel-function-modulated signatures of the ac-flux-driven diode effect, offering a robust spectroscopic tool for investigating unconventional superconductors.
