AI Article Synopsis
- Two-nucleon systems show exceptionally large scattering lengths when exposed to strong magnetic fields, specifically at unphysical quark masses.
- Lattice QCD calculations were conducted on one and two nucleon systems at pion masses of approximately 450 and 806 MeV within uniform magnetic fields of |B|∼10^{19}-10^{20} G.
- The findings suggest that such magnetic fields could influence real-world scenarios, like conditions inside magnetars and relativistic heavy ion collisions, potentially affecting the behavior of hadronic systems.
Article Abstract
Two-nucleon systems are shown to exhibit large scattering lengths in strong magnetic fields at unphysical quark masses, and the trends toward the physical values indicate that such features may exist in nature. Lattice QCD calculations of the energies of one and two nucleons systems are performed at pion masses of m_{π}∼450 and 806 MeV in uniform, time-independent magnetic fields of strength |B|∼10^{19}-10^{20} G to determine the response of these hadronic systems to large magnetic fields. Fields of this strength may exist inside magnetars and in peripheral relativistic heavy ion collisions, and the unitary behavior at large scattering lengths may have important consequences for these systems.

Horizontal Gaze Tolerance and Its Effects on Visual Sensitivity in Glaucoma.
Invest Ophthalmol Vis Sci

Department of Ophthalmology, Saitama Medical University, Saitama, Japan.
Purpose: This study evaluates the effect of 6° horizontal gaze tolerance on visual field mean sensitivity (MS) in patients with glaucoma using a binocular head-mounted automated perimeter, following findings of structural changes in the posterior globe from magnetic resonance imaging and optical coherence tomography.
Methods: In this cross-sectional study, a total of 161 eyes (85 primary open-angle glaucoma [POAG] and 76 healthy) from 117 participants were included. Logistic regression and 1:1 matched analysis assessed the propensity score for glaucoma and healthy eyes, considering age, sex, and axial length as confounders.
Observation of super-Alfvénic slippage of reconnecting magnetic field lines on the Sun.

Slipping motions of magnetic field lines are a distinct signature of three-dimensional magnetic reconnection, a fundamental process driving solar and stellar flares. While being a key prediction of numerical experiments, the rapid super-Alfvénic field line slippage driven by the 'slip-running' reconnection has remained elusive in previous observations. New frontiers into exploring transient flare phenomena were introduced by recently designed high cadence observing programs of the Interface Region Imaging Spectrograph (IRIS).

Developing purely organic room-temperature magnetic semiconductors has been a long-sought goal in the material community toward the simultaneous control of spin and charge. Organic cocrystals, known for their structural versatility and multifunctionality, are ideal candidates for these magnetoelectric coupling applications. However, organic room-temperature magnetic semiconductor cocrystals have rarely been reported, and their mechanisms remain poorly understood due to the complexity of cocrystal structures.

The modulation of intrinsic magnetic properties of materials is of great importance for the exploration of new materials in the fields of information storage and spintronics. Herein, room-temperature ferromagnetic properties in BaZrO are successfully induced using supercritical CO. The highest saturation magnetization intensity of BaZrO is observed at 16 MPa, with a value of 0.
