This paper corrects a calculation error in Fermi's 1926 note regarding the probability that partial sums remain below a threshold, clarifies the inconsistency in his final integration, and establishes that small individual variances alone are insufficient to guarantee the discrete limit without satisfying the Lindeberg condition.
This study demonstrates that indirect excitons in a high-mobility MoSe/WSe heterostructure exhibit a distinct transition from efficient transport to a Mott insulator state, characterized by a unique non-monotonic expansion and subsequent contraction of the exciton cloud that is successfully reproduced by simulations.
This study validates lanthanum oxybromide (LaOBr) as a superior gate dielectric for van der Waals heterostructures by demonstrating its high bulk dielectric constant of 12.2 and hBN-comparable breakdown fields, while establishing that its effective performance is systematically dependent on film thickness due to interfacial dead layers.
This paper theoretically proposes a fast, all-electrical control scheme for phosphorus nuclear spins in silicon called electric-dipole-induced nuclear electric resonance (EDNER), which leverages hyperfine interactions and magnetic field gradients to achieve high-fidelity quantum operations with long coherence times, thereby advancing the scalability of silicon-based quantum computing.
This study utilizes first-principles calculations to demonstrate that compressing orthorhombic Form III polytetrafluoroethylene induces an anisotropic thermal conductivity response where chain-axis conductivity consistently decreases while transverse components recover at higher pressures due to stiffer interchain forces and increased heat-capacity-weighted velocities.
This paper demonstrates that levitated dielectric sensors with transverse dimensions matching the optical mode induce a nonperturbative regime where the sensor fundamentally restructures intracavity fields into coupled subcavities, leading to significant deviations from standard optomechanical predictions in resonance frequencies, trapping stiffness, and cooling capabilities.
This study experimentally identifies Co1/4TaSe2 as a layered altermagnetic material with a Néel temperature of 178 K, using ARPES and DFT to confirm its characteristic spin splitting and temperature-dependent band reconstruction.
This paper introduces a numerically efficient real-space framework utilizing the spectral localizer and a scalable sparse factorization algorithm to classify parity-based topology in aperiodic materials, overcoming the limitations of conventional momentum-space approaches by enabling local, energy-resolved topological diagnosis in systems lacking translational symmetry.
This paper proposes and demonstrates a mechanism for dynamically reconfiguring topological routing paths in nonlinear photonic systems, specifically non-resonantly pumped polariton lattices, by utilizing driven-dissipative interactions to locally alter the system's topology and enable tunable, protected light propagation.
This article reviews the physics of magic-angle twisted bilayer graphene, focusing on its moiré superlattice and flat electronic bands as the foundation for exotic, strongly-correlated phenomena like superconductivity and Mott-like insulating states, while also addressing the limitations of classical theories and recent advances in tuning these interaction-driven states.
