标题： Horizon-Driven Expansion from Hawking-Like Radiation: A Curvature-Coupled Cosmological Model

摘要： 我们提出一个宇宙学模型，其中宇宙的膨胀是由类似于霍金的穿越宇宙视界的能量流入驱动的，而不是来自固定的宇宙常数。 代替宇宙常数，我们在弗里德曼方程和连续性方程中引入了源项，这些源项将视界曲率与物质和辐射密度耦合。 在高曲率（大哈勃参数$H$）下，这种流入强烈地补充了物质和辐射，减缓了它们的绝热稀释。 当曲率减小时，流入减弱，平滑地过渡到标准的辐射或物质主导时代。 这种机制自然抑制了空间曲率，而无需需要暴胀阶段。 它也可能通过缓慢变化的视界热力学产生近似标度不变的涨落。 显示英文摘要

摘要： We propose a cosmological model in which the expansion of the universe is driven by a Hawking-like influx of energy across the cosmological horizon, rather than from a fixed cosmological constant. In place of a cosmological constant, we introduce source terms in the Friedmann and continuity equations that couple horizon curvature to matter and radiation densities. At high curvature (large Hubble parameter $H$), this influx strongly replenishes matter and radiation, slowing their adiabatic dilution. As curvature diminishes, the influx weakens, smoothly transitioning into standard radiation- or matter-dominated eras. This mechanism naturally suppresses spatial curvature without requiring an inflationary phase. It may also produce near-scale-invariant fluctuations via slowly varying horizon thermodynamics.
