This Perspective explores how quantum geometry, arising from interband mixing and wavefunction momentum-space textures, introduces hidden length and time scales that qualitatively alter material responses and influence many-body ground states, while reviewing recent experimental advances and methods to estimate their significance.
This study demonstrates that high concentrations of intrinsic antisite defects in the topological magnet MnBiTe displace the topological surface states deep into the crystal bulk, thereby suppressing the surface gap and resolving the long-standing discrepancy between experimental observations and theoretical predictions.
This paper presents an analytical framework to model the upper critical in-plane magnetic field in quasi-2D layered superconductors, which, when applied to recent bilayer graphene experiments, reveals a discrepancy in spin-orbit parameters that is likely resolved by an enhanced Landé g-factor.
This paper demonstrates room-temperature photoelectrical detection and characterization of divacancy and PL5–PL7 spins in silicon carbide, revealing superior electrical readout capabilities for specific defects and identifying new spin parameters that advance the development of quantum electronic devices.
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.
This paper experimentally demonstrates the disorder-enabled, bulk-localized erratic non-Hermitian skin effect in a driven photonic mesh lattice, revealing a unique topological transition where wave dynamics self-organize into bulk patterns independent of boundaries, distinct from both conventional skin and Anderson localization.
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.
This paper proposes a general mechanism for the spontaneous self-doping of commensurate Wigner crystals into metallic, incommensurate phases and applies this theory to rhombohedral multilayer graphene to explain recent experimental observations of reversed Hall conductance.
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.
This paper establishes a generalized doubling theorem for -fold exceptional points in both linear and nonlinear systems by introducing frequency-momentum winding numbers as new topological invariants that characterize their topology across the Brillouin zone and reveal a previously unreported topology for -symmetric two-fold exceptional points.
