This paper reports the first experimental demonstration of electrical readout for 180-degree Néel vector reversal in atomically thin van der Waals antiferromagnetic CrSBr films by utilizing spin-dependent tunneling magnetoresistance in a heterostructure coupled to a spin-polarized layer.
This paper proposes and demonstrates a novel information processing scheme that leverages the dynamical properties of memristors rather than their multi-level resistance states, enabling complex tasks such as autonomous neural spike detection and high-accuracy time-series prediction using circuits composed of only two memristors.
This paper theoretically investigates Wigner crystallization in Bernal bilayer graphene under perpendicular displacement fields, revealing that Berry curvature induces spontaneous orbital magnetization and trigonal warping causes a "doubly re-entrant" phase behavior with nontrivial minivalley order, while also mapping the state's phase boundaries in terms of density, field, and temperature.
This paper derives and numerically explores a momentum-dependent Beth-Uhlenbeck equation for Gaussian fluctuations in a generalized 2+1D Gross-Neveu model, revealing significant deviations from previous Lorentz-boosted approximations, including the resurrection of pseudoscalar bound states and substantial contributions from Landau modes to fluctuation pressure.
This paper demonstrates that optimizing sample and circuit layouts enables VO oscillators to operate in the 100 MHz range, overcoming previous frequency limitations and paving the way for ultrafast, energy-efficient oscillating neural networks.
This paper demonstrates an electrically tunable heavy fermion phase diagram in magic-angle twisted trilayer graphene, where a displacement field controls Kondo hybridization to drive a continuous quantum phase transition from an antiferromagnetic semimetal to a paramagnetic heavy fermion metal, marked by effective mass divergence and Fermi surface reconstruction at the critical point.
This paper proposes a unified semiclassical framework for an "emergent-gravity Hall effect" driven by effective gravitational fields arising from quantum geometry, identifying four distinct mechanisms involving Christoffel symbols in real, momentum, and time spaces that can induce a finite Hall response in quantum systems.
This study combines first-principles DFT calculations, angle-resolved photoemission spectroscopy, and low-temperature heat capacity measurements to characterize the momentum-dependent charge density wave gap and construct the magnetic phase diagram of the rare-earth chalcogenide EuTe4.
This paper presents a low-power, biomimetic auditory front-end for fully implantable cochlear implants that utilizes a piezoelectric MEMS cantilever coupled with a VO memristor oscillator to achieve FFT-free, frequency-selective sensing and direct neuromorphic spike generation, thereby reducing energy consumption and system footprint compared to conventional solutions.
This paper demonstrates that strong magnetic disorder in a two-dimensional Chern insulator can fundamentally drive the emergence of novel topological phases, including a disorder-induced transition mediated by Green's function zeros and a nontrivial phase characterized by a distinct spin-configuration Chern number that vanishes in the clean limit.
