AI 中文摘要
玻色-爱因斯坦凝聚（BEC）和超流暗物质（SFDM）晕可以包含由量子化涡旋携带角动量的相干波支撑核心。当涡旋形成缠结时，重连将部分涡旋动能转化为暗声子、密度波、开尔文波和涡旋环，为SFDM涡旋结构影响晕核演化提供微观通道。我们通过结合局部格罗斯-皮塔耶夫斯基重连定律和根据薛定谔-泊松模拟校准的晕尺度涡旋线密度来估计该通道的动力学重要性。在最小模型中，释放的能量留在暗区，标准模型的光度需要额外的门户物理。
英文摘要
Bose-Einstein-condensed (BEC) and superfluid dark-matter (SFDM) halos can contain coherent, wave-supported cores whose angular momentum is carried by quantized vortices. When vortices form a tangle, reconnections convert part of the vortex kinetic energy into dark phonons, density waves, Kelvin waves, and vortex loops, providing a microscopic channel by which vortex structure can affect halo-core evolution. We estimate the dynamical importance of this channel by combining the local Gross-Pitaevskii (GP) reconnection law with a halo-scale vortex-line density calibrated against Schrödinger-Poisson (SP) simulations. Vortex reconnections cannot appreciably restructure a standard SP halo core under the fiducial assumptions: for a $m=10^{-22}$ eV, $r_c=1$ kpc soliton and a one-percent energy-transfer efficiency per event, an unforced network transfers at most $1.3\%$ of the core virial energy in 10 Gyr. Reconnection converts ordered vortex energy into sound and smaller-scale excitations; we bound the cumulative transfer using a spectral scale measured in published SP halo simulations. To connect the result with measured systems, we match the standard soliton profile to half-light masses derived with a single mass estimator for eight classical Milky Way dwarf spheroidals. Assigning the measured aperture mass to the soliton gives ceilings of $0.98-4.52\%$ at the Mocz line-density reference and $0.061-3.19\%$ for a modest-rotation normalization. The largest value is a factor of 22 below the core virial-energy scale and limits the fixed-structure velocity change to $2.3\%$. The spectral reference represents fewer than one projected vortex crossing, so these are continuum upper limits; a vortex-free core has no reconnection heating. Reconnections remain worth testing because they are unavoidable when a tangle exists.
