This paper extends the universal operator-growth hypothesis to dissipative quantum systems by demonstrating that while coupling to a Markovian environment introduces an imaginary growth rate proportional to dissipation strength, the real complexity-growth rate remains protected to second order, preserving the bound on the Lyapunov exponent without suppressing operator growth.
This paper proposes a novel quantum secret sharing framework that enables progressive reconstruction of multimedia data based on the fundamental limits of quantum parameter estimation rather than algebraic methods, allowing reconstruction fidelity to improve with the number of available quantum copies without requiring entanglement.
This paper establishes a rigorous, closed-form expression for the exact localized information capacity of local observables in Hilbert-space-shattered systems, demonstrating that this capacity is determined by the projection onto the exact commutant algebra and yields specific, non-universal bit densities (such as bits/site for the dipole-conserving chain and bit/site for the - chain) that explain why complete memory in these systems arises from statistically localized data rather than strictly local integrals of motion.
This study utilizes a Geiger-Muller counter to measure background radiation levels in Chagni Town, revealing significant spatial variations across specific locations and a higher average count during the summer season compared to winter, attributed to natural radionuclides like radon and artificial isotopes such as krypton-85.
This study reports the emergence of six-fold degenerate Dirac fermions in twisted WSe₂ moiré systems across a quantum spin Hall transition, demonstrating a new route to realizing Dirac physics in strongly spin–orbit-coupled materials and establishing a platform for high-mobility spintronics.
This paper presents experimental findings on the diffusion tortuosity of a porous medium modeled by monosized hard spheres, demonstrating how variations in porosity and skeleton shape influence tortuosity values ranging from 1.20 to 1.46 and comparing these results with theoretical predictions and existing literature.
This study validates an ad-hoc 2-D model that couples short-time parallel dynamics with long-time radial transport to accurately predict tungsten impurity profiles and radiation distributions in high-rotation KSTAR plasmas, demonstrating reasonable agreement with experimental infrared video bolometer measurements.
This paper introduces a pulsed all-optical protocol using nitrogen-vacancy ensembles in diamond that suppresses common-mode optical noise to achieve a 10-fold improvement in low-frequency sensitivity over continuous-wave techniques, while also characterizing the dependence of contrast on readout timing and dark time for optimizing diverse NV-diamond samples.
This paper derives an analytical expression for the propagation of perfect optical vortex beams through misaligned optical systems, revealing that misalignment transforms single-ring vortices into controllable multi-ring Bessel-Gauss beams at the focal plane, with specific structural characteristics dependent on topological charge and geometric ratios, before eventually reverting to a single-ring profile over longer distances.
Using two-dimensional electronic spectroscopy, researchers discovered that a platinum(II) molecular thin film exhibits long-lived electronic coherence transfer from singlet to triplet states persisting up to 680 fs at room temperature, offering new avenues for coherent control in optoelectronic and quantum technologies.
