The First Magic Angle Beyond the Chiral Limit in Twisted Bilayer Graphene

This paper introduces a squared-Hamiltonian framework demonstrating that lattice relaxation stabilizes the first magic angle in twisted bilayer graphene by balancing confinement and current-like channels near a special uniform confinement point, while simultaneously destabilizing higher-order magic angles through enhanced remote-band hybridization and localization.

Davydov Splitting Without a Davydov Pair and Highly Mobile Singlet Excitons in Perylene Red Microcrystals

This study reveals that perylene red microcrystals exhibit highly mobile singlet excitons driven by a J-like band and incoherent hopping transport, while demonstrating that the observed 610 cm⁻¹ spectral splitting arises from two distinct transitions rather than a traditional Davydov pair.

MLIP Detective: Active Failure Mode Discovery Beyond Benchmark Scores for Machine-Learning Interatomic Potentials

This paper introduces MLIP Detective, an agentic framework that uses physics-informed search to actively discover and characterize hidden failure modes in universal machine-learning interatomic potentials beyond standard benchmark evaluations, successfully identifying a systematic energy anomaly in the MACE-MPA-0 model.

From London to Morse via Binnig, Quate, and Gerber

This perspective article reviews two decades of research from the University of Nottingham that explores the full spectrum of tip-sample interactions in atomic force microscopy, emphasizing the probe's active role in phenomena ranging from van der Waals forces to covalent bonding and atom-by-atom assembly, while also addressing challenges in non-invasive diffusion measurements and the emerging application of machine learning in atomic manipulation.

Laser Shock Peening in Hydrogen Environments: Coupled Stress Transport Trapping Mechanisms and Application Gaps

This review critically evaluates Laser Shock Peening (LSP) as a surface design strategy for mitigating hydrogen embrittlement in high-strength alloys by analyzing the coupled mechanisms of compressive stress, hydrogen transport, and trapping, while identifying key gaps in quantitative performance correlations and proposing mechanism-informed qualification routes.

Phonon-Programmable Hidden Unconventional Magnetism in Two-Dimensional Spin-Degenerate Antiferromagnets

This paper demonstrates that coherent phonons in two-dimensional spin-degenerate antiferromagnets can be programmed via pump-field polarization to selectively activate hidden unconventional magnetism, thereby enabling continuous tuning of spin-splitting textures and thermoelectric spin currents without altering the underlying collinear Néel order.

Thomas-Fermi screening of electrostatic fields in a type-I superconductor

Using qPlus atomic force microscopy and scanning tunneling microscopy on single-crystal Pb(111), this study experimentally demonstrates that electrostatic screening in a type-I superconductor remains governed by the Thomas-Fermi length rather than the London penetration depth, thereby contradicting J. E. Hirsch's alternative theory and confirming that the longitudinal response is unchanged upon entering the superconducting state.

Magnetic phases of Kondo lattice materials Ce5_5RhGe2_2 and Ce5_5IrGe2_2

This study investigates the magnetic properties of single-crystal Kondo lattice materials Ce5_5RhGe2_2 and Ce5_5IrGe2_2, revealing that while Ce5_5RhGe2_2 exhibits ferromagnetic ordering similar to Ce5_5CoGe2_2, Ce5_5IrGe2_2 displays a complex ferrimagnetic ground state characterized by multiple magnetic transitions and metamagnetic plateaus.
