By engineering the stacking configuration and twist angle of orthogonally-twisted CrSBr van der Waals magnets, researchers demonstrate a highly tunable magnetic hysteresis that enables on-demand switching between volatile and non-volatile memory states and controls abrupt spin-reversal processes, offering a new pathway for miniaturized spintronic devices.
Through numerical simulations of a finite-temperature two-skyrmion system, this study reveals asymmetric information flow violating detailed balance and identifies a box-size-dependent transfer entropy peak that characterizes state-change times, suggesting potential applications in natural computing.
This paper proposes that heterosheared bilayer graphene hosts high-temperature superconductivity driven by 1D moiré flat bands, where valley polarization enables Cooper pair condensation by spatially separating electrons of opposite spins to minimize Coulomb repulsion.
This paper establishes a unified theoretical framework based on spinful quasiperiodic systems that achieves exact solvability for all seven fundamental localization phases, including novel models with mobility edges, and proposes feasible experimental schemes for their realization.
This paper extends the analysis of critical Fermi surface deformations at an Ising-nematic quantum critical point by employing quantum Boltzmann equations that include collision effects, revealing that while bosonic dynamics do not alter the solutions, the system supports a robust zero-sound mode and an infinite family of discrete higher-order harmonic modes alongside a continuous particle-hole band.
By leveraging electrostatic control of Landau-level crossings in high-quality bilayer graphene devices, this study demonstrates that enhanced Landau-level mixing near orbital crossings stabilizes electronic crystals over topological fractional quantum Hall liquids at constant filling factors, revealing distinct transition characteristics and evidence for a paired composite fermion state.
This study demonstrates that epitaxial growth of monolayer NbSe on graphite naturally forms moir{é} superlattices where interlayer coupling between graphite states and NbSe suppresses charge-density wave enhancement, offering a new pathway for controlling collective states in 2D materials without manual assembly.
By utilizing Coulomb engineering to tune dielectric screening in ultra-clean TiSe heterostructures, the study demonstrates that while the band gap is renormalized, the charge-density-wave transition remains unaffected, thereby ruling out excitonic insulator physics as the primary driver of the phase transition in TiSe.
This paper demonstrates that applying commensurable two-tone Floquet drives to fluxonium qubits enhances coherence by creating tunable dynamical sweet spots with wider dephasing time peaks and enables improved phase gate performance compared to single-tone drives.
Using scanning tunnelling microscopy to analyze the local density of states near defects, this study experimentally confirms the topological obstruction and key band structure features of magic angle twisted bilayer graphene, including chirality patterns, Lifshitz transitions, and Fermi velocity renormalization.
