A Fourier-Space Approach to Physics-Informed Magnetization Reconstruction from Nitrogen-Vacancy Measurements

This paper introduces a physics-informed, Fourier-space reconstruction method using an auto-differentiable micromagnetic framework to accurately recover complex magnetization textures and simultaneously determine unknown sensor-sample distances from nitrogen-vacancy magnetometry data.

Evidence of Metallic Wigner Crystal in Rhombohedral Graphene

This study reports transport evidence for both a pinned insulating Wigner crystal and a coexisting metallic Wigner crystal in rhombohedral multilayer graphene, achieved by tuning the displacement field to flatten the conduction band and observing distinct nonlinear, hysteretic, and quantum Hall signatures.

A footprint of zero-point entropy in higher-temperature magnetic thermodynamics

This paper proposes a simple, experimentally accessible signature for detecting nonzero zero-point entropy in magnetic materials—specifically a violation of Maxwell's relation or a specific inequality involving heat capacity and magnetization derivatives—demonstrating its utility through the benchmark case of the spin ice Dy2Ti2O7Dy_2Ti_2O_7.

Dielectric control of ultrafast carrier dynamics and transport in graphene

This paper demonstrates that engineering the dielectric environment of graphene provides a powerful means to externally control ultrafast carrier heating and cooling dynamics, as well as enhance charge mobility and the Seebeck coefficient, by suppressing carrier-carrier interactions without altering the Fermi energy or ambient conditions.

Field-unmasked quantum geometry in a symmetry-forbidden photocurrent

This study reveals how an applied magnetic field selects defect-induced spin ordering in a chiral cubic sillenite to lower its effective symmetry, thereby unmasking a forbidden longitudinal magneto-photocurrent that serves as a sensitive probe of hidden Berry curvature and quantum metric.
